## Guides and Pages

Each guide is a collection of pages. The top level guide is the main page, and each page can have next and previous pages and are linked at the end of each page. To view all of the content for any guide, add the parameter view=all to any of the urls. This will increase the context size. Most links will also output markdown with the .md extension added to the end as shown below.

### TTL Serial Camera
This guide is for our new TTL serial camera module with NTSC video output. These modules are a nice addition to a microcontroller project when you want to take a photo or control a video stream. The modules have a few features built in, such as the ability to change the brightness/saturation/hue of images, auto-contrast and auto-brightness adjustment, and motion detection.

### Adafruit LED Backpacks
What's better than a single LED? Lots of LEDs!  The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface.

Here is a detailed guide showing you how to solder, wire and control the display.

### Thermistor
A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree! This guide will teach you how thermistors work, and how to wire them up and use them with your favorite microcontroller.

### Adafruit Pi Cobbler Kit
Once soldered together, the cable plugs between the Pi computer and the Cobbler breakout. The Cobbler can plug into any solderless breadboard (or even a prototyping board like the PermaProto). The Cobbler PCB has all the pins labeled nicely so you can go forth and build circuits without keeping a pin-out printout at your desk. We think this will make it more fun to expand the Pi and build custom circuitry with it.

### Monochrome OLED Breakouts
This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

### Raspberry Pi E-mail Notifier Using LEDs
Raspberry Pi’s popularity makes things so easy that it is almost scary. I set forth on a simple starter project of having the Pi show me when new GMail messages arrive. After some searching it seems that lots of people are already talking about how to do this and there are some great examples. Michael over at MitchTech had the most ready to go code which I pilfered from. Adafruit's Cobbler Breakout Kit makes the bread board experience even easier with the clearly labeled pins for each of raspi’s GPIOs.

### 0.96" mini Color OLED
Our 0.96" color OLED displays are perfect when you need an ultra-small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 0.96" diagonal and contains 96x64 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). We picked this display for its excellent color, this is the nicest mini OLED we could find.  This guide will show you how to hook it up and use it with an Arduino.

### Li-Ion & LiPoly Batteries
If you want to take your project portable you'll need a battery pack! For beginners, we suggest alkaline batteries, such as the venerable AA or 9V cell, great for making into larger multi-battery packs, easy to find and carry plenty of charge. If you want to go rechargeable to save money and avoid waste, NiMH batteries can often replace alkalines. Eventually, however, you may want to upgrade to the shiniest new technology - rechargeable lithium ion/polymer batteries.  In this guide, you will learn all about these batteries, and how to properly use them in your projects.

### Analog Inputs for Raspberry Pi Using the MCP3008
Teaching the raspberry pi how to read analog inputs is easier than you think. The Pi does not include a hardware analog to digital converter, but a external chip can be used along with some bit banged SPI code in python to control read external analog devies such as (but not limited to):

- potentiometer
- photocell
- force sensitive resistor ( fsr )
- temperature sensor

### Drive a 16x2 LCD with the Raspberry Pi
Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down the bare metal. This technique allows for less expensive LCDs to be used, it does not require any i2c drivers and it won't steal the only serial port on the Pi.

### DHT Humidity Sensing on Raspberry Pi or Beaglebone Black with GDocs Logging
In this tutorial we'll be showing how to utilize a DHT sensor Python library based on C for high-speed GPIO polling to handle bit-banged sensor output. Many low cost sensors have unusual output formats, and in this case, a "Manchester-esque" output that is not SPI, I2C or 1-Wire compatible must be polled continuously by the Pi to decode. Luckily, the C GPIO libraries are fast enough to decode the output.

### I2C/SPI LCD Backpack
LCDs are a fun and easy way to have your microcontroller project talk back to you. We wanted to make a 'backpack' (add-on circuit) that would reduce the number of pins without a lot of expense.

By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD.

### How to Make a Pogo Pin Test Jig
If you end up buying a pick and place to assemble PCBs (or even if you're doing it by hand) you'll need to test out your boards! If you have an assembler do it for you, its still probably a good idea to have a jig you can give them. A good jig will tell you whats going right and whats going wrong.

In this tutorial I will show how I designed a very basic jig with a "tested good" audible indicator. The board its testing is very simple but the basic premise can be expanded to large projects with ease.

### Adafruit 16x2 Character LCD + Keypad for Raspberry Pi
This new Adafruit Pi Plate makes it easy to use an RGB 16x2 Character LCD. We really like the RGB Character LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins.  With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the R-Pi!

### RGB LED Strips
We love some good LED blinking as much as the next person but after years of LED-soldering we need something cooler to get us excited. Sure there are RGB LEDs and those are fun too but what comes after that? Well, we have the answer: LED Strips! These are flexible circuit boards with full color LEDs soldered on. They take a lot of LED-wiring-drudgery out of decorating a room, car, bicycle, costume, etc.

Here is a quick tutorial on how to get an LED strip working with an Arduino.

### USB NeXT Keyboard with an Arduino Micro
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! We spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between. Now this lovely black deck works like any other USB keyboard. Sure it weighs more than our Macbook, but its worth it!

### RGB LED Matrix Basics
Bring a little bit of Times Square into your home with our RGB LED matrix panels. These panels are normally used to make video walls — here in New York we see them on the sides of buses and on bus stops — to display animations or short video clips. We thought they looked really cool so we picked up a few boxes from the factory.

### 2.8" TFT Touchscreen
Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (16-bit 262,000 different shades)! 240x320 pixels with individual pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

### Lady Ada's Bento Box
Portage for your projects! Lady Ada's Bento Box is a crush-proof, drop-proof & water-proof prototyping kit that combines the ultra-rugged Otterbox 3000 with a storage tin and half-size (400-point) breadboard. In the middle is a spot for attaching an Arduino UNO (or any other PCB that has the same shape and mounting holes). There's plenty of clearance for wires (even ones with plastic bits on the end such as our premium jumper wires or wire bundles) and parts on the breadboard, and the box is so sturdy you never have to worry about any delicate parts inside getting damaged. Toss it in your backpack, suitcase, duffel bag and you can be sure to work on it when you get to school, work or home.

### Flora Accelerometer
Add motion and direction sensing to your wearable Flora project with this high precision 3-axis Accelerometer+Compass sensor. Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. By combining this data you can then orient yourself.

This project is the third revision of the MiniPOV. This version is nearly identical to the last version, MiniPOV2 but uses the serial port (possibly with a USB/Serial converter) instead of a parallel port, for programming. Because the programmer is built into the kit, one does not need a special "microcontroller programmer". This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).

### Decompiling .NET Apps
Have a lackluster datasheet for your sensor, but a demo app from the vendor that seems to calculate the value you need?  If the app is written in .Net (Visual Basic or C#) -- and if it's Windows based, it probably is -- you might be able to decompile the app and find that magic formula you're looking for!

### Large Pi-based Thermometer and Clock
This project combines a whole heap of modules to enable a Raspberry Pi to power a large 1.2 inch 4 digit 7 segment display. A small switch switches the display between showing the temperature and the current time. The project uses a real-time clock (RTC) to ensure that the Pi always has the correct time, even if it is not connected to the Internet.

### XBee Radios
XBee modems are one of the easiest ways to create a wireless point-to-point or mesh network. They have error correction, are configured with AT commands, come in multiple flavors and can create a wireless serial link out of the box! I wanted to make a wireless Arduino project but all the adapter boards on the market made me unhappy. So I designed what I think is an excellent low-cost adapter board.

### How To Take Great Photos of Your Projects
This tutorial by John De Cristofaro (johngineer) aims to teach you how to take photos of your hacks and projects for sharing on the web, and perhaps even in print. It focuses on smaller items, less than 6”x6”x6” in size. Bigger projects present their own unique problems that are beyond the scope of this article. However, you can always “scale up” the methods presented here to take pictures of larger subjects, at least to a point.

### Dimmable Li-Ion Halogen Bike Light
A good front-light is essential, not only for being seen, but to see the road. LED lamps will not illuminate the road, and they can be too dim for cars to see you (1W or better LEDs are quite nice as headlamps.) I offer here a simple (but high-quality) design to build your own 5 or 10W halogen lamp, which runs off of a rechargeable 7.2V or 7.4V Lithium Ion battery pack.

### Halloween Pumpkin
Here is a quick project for an electronic Halloween pumpkin. With a bit of hacking a $1 plastic pumpkin is upgraded: a sensor embedded in the nose detects when people get close and will play scary sounds and animates LEDs on the face. The sounds are stored on an SD card so its easy to change and customize what the pumpkin says, while the code is written for an Arduino so it's easy to modify the behavior. I'm going to have this pumpkin outside my door to freak out the little kids who go to daycare nearby. Boo!

### How To Start A Hackerspace: The List
This document is "The List" - it is the direct result of the overwhelming interest in starting Hackerspaces that hit my inbox after co-founding PSOne and HacDC. When so many people asked for help with the very basics of starting and running a successful Hackerspace, I compiled this list to make it as easy as possible for potential Hackerspace founders to hit the ground running (and not forget anything important). 

Since then, “the list” has been distributed and shared within Hackerspace culture. It has helped with structuring the success of many Hackerspaces - and hopefully with this update and public release, it will serve as a handy go-to checklist for your awesome Hackerspace-to-be.

### Sous-vide controller powered by Arduino - The SousViduino!
Sous vide is rapidly becoming an important cooking technique in many of the very best restaurants in the world. It combines principles of molecular gastronomy with industrial temperature controls to precisely manage the chemical reactions of cooking.

We love good food as much as we love science and technology, so we had to build our own sous vide controller. This project turns an inexpensive rice cooker into a precision cooking instrument.

Join the high-tech cooking revolution by building your very own sous vide controller!

### Standalone AVR Chip Programmer
Instead of having a computer that talks thru the Arduino to a chip for programming, instead the Arduino itself programs the chip. This means you can program chips without having a computer involved. The good news about this technique is that it is incredibly fast, you can program chips 10x faster than with a computer and without having to type anything in.

### Adafruit MENTA Kit
Introducing the MENTA, a portable minty Arduino-compatible project that fits into a common mint tin. We took our super popular Boarduino series, and wrapped it with a prototyping area into a rounded PCB that slots directly into an Altoids-sized metal tin. We included everything you expect to jump-start your project: a DC power adapter with polarity protection, beefy 1 Amp 5V regulator and 250mA 3.3V regulator for 3.3V devices, green power LED, red blinky LED, ISP-6 standard reprogramming header, FTDI interface plug to connect an FTDI Friend or cable and female header so you can plug standard Arduino-compatible shields in. There are four mounting holes if you want to attach it permanently to a box or plate, and a massive prototyping area so you can have the finished project all fit together in a protective box.

### Micro SD Card Breakout Board Tutorial
If you have a project with any audio, video, graphics, data logging, etc in it, you'll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. There's more flash (256K) but you cant write to it as easily and you have to be careful if you want to store information in flash that you don't overwrite the program itself!

### Atmega32u4 Breakout
We like the AVR 8-bit family and we're excited to see Atmel upgrade the series with a USB core. Having USB built in allows the chip to act like any USB device. For example, we can program the chip to 'pretend' it's a USB joystick, or a keyboard, or a flash drive! Another nice bonus of having USB built in is that instead of having an FTDI chip or cable (like an Arduino), we can emulate the serial port directly in the chip. This costs some Flash space and RAM space but that's the trade-off.

### Analog Feedback Servos
The very word "servo" implies feedback-based control.  But for most RC servos, that feedback signal is not available outside the servo case.  So when controlling them from a microcontroller, you never really know if the servo is doing what you tell it to do.

These feedback servos have an extra wire for the feedback signal.  This lets you monitor the  servo motion to verify that it is working as expected.  It also lets you use the servo as an input device.

### NeoPixel Painter
Light painting is an artistic medium combining light, motion and long-exposure photography. For as long as a camera’s shutter is open, a single point of light in motion will create a continuous streak in the final photograph.

Digital technology takes light painting to the next level…dozens of point lights, with color and brightness individually under computer control, weave a swath of awesome across the completed frame.

Adafruit’s NeoPixel strips, combined with the Arduino microcontroller and a supporting cast of parts, make highly refined digital light painting achievable!

### Introducing Bluefruit EZ-Link Breakout
We are excited to add another product to our growing Adafruit Bluefruit line, this time its the Bluefruit EZ-Link: the best Bluetooth Serial Link device ever made. Like you, we have purchased all sorts of Bluetooth serial link modules, with high expectations - we just wanted something that worked! But nothing ever did exactly what we wanted: there was always some configuration modes to wade through, and using one of those other modules to reprogram an Arduino is impossible.

So we did what we always do, we went in and engineered something better. Something that works!

### Introducing Adafruit Trellis 
Trellis is an open source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus.
Each Trellis PCB has 4x4 pads and 4x4 matching spots for 3mm LEDs. The circuitry on-board handles the background key-presses and LED lighting for the 4x4 tile. However, it does not have any microcontroller or other 'brains' - an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired.

Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic "LM386" amps!

### Adafruit AGC Electret Microphone Amplifier - MAX9814
This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change and you don't want to have to tweak the amplifier gain all the time.

### Adafruit 1-Wire GPIO Breakout - DS2413
Pins are precious in the microcontroller world. How many times have you needed just one more pin?  Sure, you could step up to a Mega and get a bunch more, but you really just need one or two. The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one.  But you can keep expanding from there.

You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin.  Each chip has a 48-bit unique address, which means you could have as many as 562 trillion GPIO pins!  (In theory anyway)

### Using Melexis MLX90614 Non-Contact Sensors
This cyber-tronic looking sensor hides a secret behind it's glimmering eye. Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. Because it doesn't have to touch the object it's measuring, it can sense a wider range of temperatures than most digital sensors: from -70°C to +138°C It takes the measurement over an 90-degree field of view so it can be handy for determining the average temperature of an area.

### Adafruit I2C FRAM Breakout
FRAM is 'ferroelectric' RAM, which has some very interesting and useful properties. Unlike SRAM, FRAM does not lose the data when power is lost. In that sense it's a durable storage memory chip like Flash. However, it is much faster than Flash - and you don't have to deal with writing or erasing pages.

### Adafruit LSM9DS0 Accelerometer + Gyro + Magnetometer 9-DOF Breakouts
Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.

### Adafruit Bluefruit EZ-Link Shield
We are excited to add another product to our growing Adafruit Bluefruit line, this time it's the Bluefruit EZ-Link Shield: the best Bluetooth Serial shield ever made. Like you, we have purchased all sorts of Bluetooth shields with high expectations - we just wanted something that worked! But nothing ever did exactly what we wanted: there was always some configuration modes to wade through, and trying to reprogram an Arduino is impossible.

So we did what we always do, we went in and engineered something better. Something that works!

### AR1100 Resistive Touch Screen Controller Guide
The AR1100 is a nice chip that acts as a touch->USB converter and also comes with calibration software. The calibration software is Windows only, but once you've calibrated you can use the screen on any OS. The AR1100 shows up as a regular Mouse or Digitizer HID device so no drivers are required and it works on any operating system that supports a USB mouse (that is, every single one we've ever seen) There is also a red LED that lights up to indicate when a touch has been detected.

### Multi-tasking the Arduino - Part 1
Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects.  That usually involves combining bits and pieces of simpler sketches and trying to make them work together.  The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others.  There are ways to effectively juggle multiple tasks on an Arduino.  This series of guides will show you how.

### The Pixif
A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels.  After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream.  The update rate may be throttled via a synchronization input.  This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.

### Adafruit 16-Channel PWM/Servo HAT & Bonnet for Raspberry Pi
The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT or Bonnet! They bot add the capability to control 16 Servos with perfect timing. They can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.

### NextBus transit clock for Raspberry Pi
For transit-bound people, NextBus — a free internet service providing arrival data for over 135 transit agencies — is a tremendous convenience. Knowing when a bus is due means less standing out in the rain…one can use that time inside to get a little extra work done, or finish that cup of coffee. Using the Raspberry Pi computer, we’ll create a dedicated NextBus “appliance” that informs at a glance.

### Running OpenGL-based Games & Emulators on Adafruit PiTFT Displays
Adafruit’s PiTFT displays link to the Raspberry Pi’s GPIO header instead of a video port, making them compact & ideal for portable projects. But this connection normally limits them to a subset of specially-compiled games and emulators — high-performance OpenGL-based games were previously incompatible. New software now makes gaming more practical on these tiny displays!

### Adafruit HUZZAH ESP8266 breakout
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!

### Genesis Poi: DotStar LED Persistence-of-Vision
Persistence of vision (POV) is the illusion of a solid image where there is none — a task for which LEDs and microcontrollers are a natural fit. Poi is a performance art of spinning tethered weights. Some of the most dramatic performances use fire poi! We sought to create something with that level of “wow,” but safer and usable indoors or out. And so these “Genesis” POV-poi were born.

### 1.5" & 2.4" Monochrome 128x64 OLED Display Module
If you've been diggin' our monochome OLEDs but need something bigger, this display will delight you! These displays are 1.5" and 2.4" diagonal, and very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white OLED pixels, each one turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this graphic display for its crispness!

### Adding Basic Audio Ouput to Raspberry Pi Zero
To keep the Raspberry Pi Zero as low cost and small as possible, the Pi foundation didn't include a 3.5mm audio jack. There's also no breakout pads for the audio output. This made us a little :( at first but then we thought "hey you know, we can probably figure out how to get audio out with a little hacking!

### 3D Printed Hoverboard GoPro Mount
Self balancing scooters (hoverboards) can make an imagine stabilizer camera rig that can be used to capture smooth, low angle shoots. Mounting a small camera to the body of the scooter can be challenging because the center part of the board twists while in operation. With a 3D printed adapter, we can add clamp a camera mount to the middle of the board without obstructing riding or interfering with the position of the camera mount.

### Raspberry Pi Pygame UI basics
This guide starts with the absolute basics to build user interfaces on the PiTFT in Pygame. It shows how to update the screen from a GPI. Then, in reverse, the touch screen is used to control a GPO. Next, a UI framework is introduced - this makes better looking interfaces and more elegant code. Finally, an analog input is used to control a gauge widget on the display.

### Using ATSAMD21 SERCOM for more SPI, I2C and Serial ports
When we first checked out the ATSAMD21 chip (the processor used in the Arduino Zero and Adafruit Feather M0), we were very happy to see that the chip has 6 "SERCOM"s, a.k.a SERial COMmunication modules. Each one of these modules can be used for I2C, SPI or Serial. That means you can have 3 UART's & 3 SPI's, or maybe 2 SPI's and 4 I2C's. Basically, you have a ton of options for adding more hardware support for the most common 3 chip-to-chip protocols.

### Adafruit Stepper + DC Motor FeatherWing
A Feather board without ambition is a Feather board without FeatherWings! This is the DC Motor + Stepper FeatherWing which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors).  Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other FeatherWing or with itself (just make sure you have each wing with a unique I2C address)

### Glowing LED Team Badge for Pokemon Go
Pokemon GO has shown us that people can really go crazy over running around our cities bent on catching imaginary animals. It has also shown us that people are going crazy over chasing down said animals at all hours of the night and not always paying attention to what is going on around them. This is amplified when we are talking about children that are having a blast literally trying to catch them all.

Build a safety light that's also a lovely way to show team spirit with this no-solder project!

### Ladyada's Learn Arduino - Lesson #2
OK you've gotten your Arduino set up and also figured out how to use the software to send sketches to the board. Powerful stuff!
But...just running example sketches is a little boring. What we really want to do is use our own creativity and skill to write new sketches! That's what we'll be doing in this lesson.
To start we will venture deep into the Blink sketch, looking at each line and trying to understand what its doing.
Then we will start hacking the sketch, and maybe even meet an internationally-famous DJ and design custom hardware for him!

### Deciphering Strange Arduino Code
Working one’s way up from the Arduino “blink” sketch into increasingly sophisticated projects, part of the process entails more exposure to others’ code…open source projects, libraries that encapsulate particular functionality and so forth. Such code originates from folks of all backgrounds and skill levels, and you will invariably encounter some head-scratching moments. Not necessarily BAD code, but WEIRD.

### ISS Pin
A Particle Photon microcontroller and an Adafruit Neopixel ring combine to make a pin that's fit for NASA fans. It displays an orbiting white blip when idle and then turns blue, white and red when the ISS flies by. The code makes use of IFTTT (If This Then That), a free site that makes connecting IoT devices as easy as a few clicks. This project was inspired by my first NASA Space Apps Challenge with friend Brooks Rampersad--an ISS Orbit Skirt.

### Adafruit MAX31856 Universal Thermocouple Amplifier
Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy!

This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple

### Schluff - The Sleep Monitor
Schluff is a Yiddish word which means to take a short nap. This project is about finding the ideal environment for quality sleep by monitoring different conditions and biometric data. Ideally, the data from this device would be overlayed with a wrist-based fitness tracker for additional revelations. Schluff records the following: temperature, humidity, light, noise and heart rate. The collected data is sent from a Feather 32u4 (Arduino compatible) over to an iOS device or macOS laptop using BLE (Bluetooth Low Energy). The BLE catchers can save the data locally or relay it up to adafruit.io for storage and graphing.

###  Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board
Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver. Like that chip, you get 2 full H-bridges, but this chip is better for low voltage uses (can run from 2.7V up to 10.8V motor power) and has built in current limiting capability. We set it up for 1A current limiting so you don't get more than 2A per chip, but you can also disable the current limiting, or change it to a different limit!

### MAC Address Finder
In most situations finding the MAC address of a wireless device is fairly straightforward. However, there are some things like smart TVs, IOT devices, gaming consoles, etc. that either don't display that MAC or have it hidden in a mess of on-screen menus.

### Adafruit VL53L0X Time of Flight Micro-LIDAR Distance Sensor Breakout
The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L0x is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.

### Adafruit LSM9DS1 Accelerometer + Gyro + Magnetometer 9-DOF Breakout
Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.

### Adafruit I2S MEMS Microphone Breakout
For many microcontrollers, adding audio input is easy with one of our analog microphone breakouts. But as you get to bigger and better microcontrollers and microcomputers, you'll find that you don't always have an analog input, or maybe you want to avoid the noise that can seep in with an analog mic system. Once you get past 8-bit micros, you will often find an I2S peripheral, that can take digital audio data in! That's where this I2S Microphone Breakout comes in.

### Adafruit TPL5110 Power Timer Breakout
With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when its time to turn around and make that project of yours run on a battery or solar? Sure you could try to hot-air that regulator off, or you could jerry-rig a relay. Or, use a 555? Ugh, the options aren't that great.

### Adafruit 128x64 OLED Bonnet for Raspberry Pi
If you'd like a compact display, with buttons and a joystick - we've got what you're looking for. The Adafruit 128x64 OLED Bonnet for Raspberry Pi is the big sister to our mini PiOLED add-on. This version has 128x64 pixels (instead of 128x32) and a much larger screen besides. With the OLED display in the center, we had some space on either side so we added a 5-way joystick and two pushbuttons. Great for when you want to have a control interface for your project.

### I2C Addresses and Troublesome Chips
I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins. The only bad news about I2C is that each I2C device must have a unique address - and the addresses only range from 0 to 127 (aka 0 to 0x7F hex). Since we deal with so many I2C devices we thought it would be handy to have a table with all the most common sensors and modules we encounter, and their I2C address! We also describes some problems with certain I2C device.

### Adafruit Gemma M0
The Adafruit Gemma M0 may look small and cute: round, about the size of a quarter, with friendly alligator-clip sew pads. But do not be fooled! The Gemma M0 is incredibly powerful! We've taken the same form factor we used for the original ATtiny85-based Gemma and gave it a power up. The Gemma M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse.

### Motion-Activated Solder Fume Extractor With Lamp
A different take on the beginning maker's second project (a clock being the first, of course). We added a motion detector to activate the fan when you're soldering and a USB reading light to eliminate the shadows. The unit employs a USB-rechargeable lithium-polymer battery and provides a separate USB port for the lamp. This solder fume extractor fits into an off-the-shelf enclosure; 3D printing isn't required. Drilling and cutting the enclosure requires some intermediate fabrication skills, but a layout and drilling template is provided to make it easier to prepare the plastic case.

### Adafruit Metro Mini
We sure love the ATmega328 here at Adafruit, and we use them a lot for our own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. METRO Mini is the culmination of years of playing with AVRs: we wanted to make a tiny, breadboard-friendly development board that is easy to use and is hacker friendly. Metro Mini can be programmed with the Arduino IDE (select 'UNO' in the boards dropdown)

### Adafruit TPL5111 Reset Enable Timer Breakout
The Adafruit TPL5111 Reset Enable Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low

### Adafruit nRF52 Pro Feather with Mynewt
The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.

### Pi Hole Ad Blocker with Pi Zero W
This project will turn your Raspberry Pi Zero W into an ad-blocking local DNS server with Pi Hole. When it is asked for the IP address of ads.adserver.com (for example) it will return nothing! So you will never even connect to the ad server and get the ad. Your connection will be faster, less data, and no intrusive ads. It works great on computers, tablets, phones, etc. Even if you cannot run an ad-blocker plugin on your phone or tablet, this will work and ad-blocker-detectors can't tell you're running it.

### Adafruit Circuit Playground Express
We've taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program. The board is round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Circuit Playground Express has built-in USB support. Built in USB means you plug it in to program it and it just shows up, no special cable or adapter required. Just program your code into the board then take it on the go!

### Adafruit I2S Stereo Decoder - UDA1334A
This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. It's affordable but sounds great! The NXP UDA1334A is a jack-of-all-I2S-trades: you can use 3.3V - 5V logic levels (a rarity), and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output. It's even cool with MCLK-less I2S interfaces such as the Raspberry Pi (which it's ideal for) - a built in PLL will generate the proper clock from the bitclock signal.

### Introducing ItsyBitsy 32u4
What's smaller than a Feather but larger than a Trinket? It's an ItsyBitsy! Small, powerful, Arduino-compatible - this microcontroller board is perfect when you want something very compact, but still with a bunch of pins.
Itsy Bitsy is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital pins with plenty of analog in and pwm out. It packs much of the same capability as an Arduino UNO. So it's great once you've finished up a prototype on a bigger Arduino, and want to make the project much smaller.

### Using VCNL4010 Proximity Sensor
The sensor uses an infrared LED to bounce light off objects in front of it and time how fast it takes for the light to return.  You could do all this yourself with LEDs and light sensors, but the VCNL4010 wraps all that logic up into a stand-alone chip for you!  With the VCNL4010 you can easily read the proximity (i.e. if an object is near or far) and even ambient light level over a simple I2C connection.

### LED Breath Stats Mask
Combining Adafruit’s CCS811 gas sensor with a Circuit Playground Express and two NeoPixel Sticks we can quickly put together a mask that displays our breath attributes. This setup will monitor temperature, carbon dioxide, and total volatile organic compounds. The sensor is easy to work with using its I2C interface and pre-calibrated ranges. A mask is an ideal wearable as it provides a place to house the electronics as well as an option for continuous monitoring as it is a hands-free device that could be adapted for exercise or sleep. The gas sensors TVOC monitoring can be used as an indicator of ketosis as it will detect acetone levels on the breath which is a by-product of producing ketones. CO2 levels can also be a helpful indicator of how much glucose is being burned versus fats.

### Controlling a Classic Nintendo R.O.B. Robot Using Circuit Playground Express
Nintendo released the R.O.B with the Nintendo Entertainment System (NES) back in 1985. Only two games ever used R.O.B.s capabilities and Nintendo shipped later units without R.O.B. Dust off your R.O.B. and control him with wirelessly with a simple CircuitPython program.

### Introducing ItsyBitsy M0 Express
ItsyBitsy M0 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (12 of which can be analog in, 1x analog out, and 13x PWM out). It's the same chip as the Arduino Zero and packs much of the same capability as an Adafruit Metro M0 Express or Feather M0 Express but really really small. So it's great once you've finished up a prototype on a Metro M0 or Feather M0, and want to make the project much smaller. It even comes with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code.

### Adafruit eInk Display Breakouts and FeatherWings
Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-color eInk display. Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

### Android GBoard Morse Code Control with Circuit Playground Express
GBoard is an alternate keyboard for Android Devices that lets you type using Morse code. This has seen use for people with limited mobility, but it can also be useful for practicing your morse code skills. The goal of this project is to build a simple input device for GBoard that doesn't require soldering or elaborate construction techniques.

We'll be using a Circuit Playground Express to build this project. We have a few different versions we'll be demonstrating - from the simplest using the two onboard buttons, to using capacitive touch inputs, to connecting up some alligator clips to big-and-easy-to-press arcade buttons.

### Adafruit Mini TFT with Joystick Featherwing
This FeatherWing has so much stuff going on, we could not fit any more parts on the PCB! There's a 0.96" 160x80 Color TFT Display with 16-bit full color capability. And, so you can make a proper UI we added a 5-way navigation switch and two push buttons. The joystick can go left, right, up, down and 'in' for selection. Two buttons on the side can change modes or whatever you like.

### Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor
Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal. Even if they're gold plated! The resistivity measurement goes up and up, so you constantly have to re-calibrate your code. Also, resistive measurements don't always work in loose soil. This design is superior with a capacitive measurement. Capacitive measurements use only one probe, don't have any exposed metal, and don't introduce any DC currents into your plants.

### Circadian Pi Desk Light
Blue light in the morning and red light in the evening can help us adopt a more natural circadian rhythm. Blue light is stimulating and ideal to be exposed to early in the day while the removal of blue light allows melatonin production to ramp up so red light in the evening can help get us ready for bed. The Raspberry Pi is the perfect device to help with the timing and driving of long NeoPixel strips. In this post we will show how just a few wires, some code and a tiny bit of hardware we can have a light with some circadian awareness.

### AdaBox 011
Reach out beyond your desk - to the stars and beyond, with PyPortal! This ADABOX features a new, easy-to-use IoT device that allows you to customize and create your very own "Internet of Things" portal. We take CircuitPython to the max, pairing a SAMD51 chip with a 3.2" color TFT touchscreen and secure Wi-Fi co-processor. 

With the open-source Python-powered PyPortal, you can fetch and display anything in the world: inspirational quotes, weather forecasts, your social media followers, cat photos, and more - over Wi-Fi with the latest technologies. Create little pocket universes of joy that connect to something good. You can even rotate it 90 degrees, now it's a web-connected conference badge - and take #badgelife to the next level!

Thanks to the generous sponsorship and support from Analog Devices and Digi-Key, we've even included a fancy precision temperature sensor! Each PyPortal comes with an ADT7410 sensor built right in, so you can display the local temperature or use the PyPortal as a remote temperature logger and sensor that uploads data to our free adafruit.io IoT service.

### Currying in CircuitPython
Partially applying functions (commonly known as currying, after Haskell Curry who came up with the idea) involves giving functions their arguments in dribs and drabs rather than all at once. It might be a strange idea if you've never done any Functional Programming, but it can be incredibly useful. And, it can be done in Python.

### Data Logging IoT Weight Scale
How many grams of coffee did I add to my pour-over? Is the bag of cat food empty? Did I remember to water the plant? You're going to build an internet-enabled scale to track weight data over a period of time.

To do this, you'll be performing a bit of hardware hacking - tearing down a DYMO Postage scale and soldering wires to connect it to a PyPortal. Then, you'll add some CircuitPython code to the PyPortal which allows you to read the the scale remotely using Adafruit IO - our easy-to-use internet of things service.

### Adafruit VEML7700 Ambient Light Sensor
The VEML7700 makes your life easier by calculating the lux, which is an SI unit for light. You'll get more consistent readings between multiple sensors because you aren't dealing with some unitless values. The sensor has 16-bit dynamic range for ambient light detection from 0 lux to about 120k lux with resolution down to 0.0036 lx/ct, with software-adjustable gain and integration times. It uses I2C so it's super easy to add to your project!

### Adafruit PyBadge and PyBadge LC
The PyBadge is a compact board, it's credit card sized. It's powered by our favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. We add 2 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets. On the front you get a 1.8" 160x128 color TFT display with dimmable backlight - we have fast DMA support for drawing so updates are incredibly fast. There's also 8 silicone-top buttons, they are clicky but have a soft button top so they're nice and grippy. There's also NeoPixel LEDs to dazzle or track activity.

### Introducing Adafruit PyGamer
What fits in your pocket, is fully Open Source, and can run CircuitPython, MakeCode Arcade or Arduino games you write yourself? That's right, it's the Adafruit PyGamer! We wanted to make an entry-level gaming handheld for DIY gaming, and maybe a little retro-emulation. It's not the fastest and best of everything but it is an all-in-one dev board with a lot of possibilities! The PyGamer is powered by our favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. We add 8 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets.

### Adafruit AirLift FeatherWing - ESP32 WiFi Co-Processor
Give your Feather project a lift with the Adafruit AirLift FeatherWing - a FeatherWing that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite Feather (like the Feather M4) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in).

### Bringing Back THE VOICE of Speak & Spell
What makes the original Speak & Spell voice so distinctly Speak & Spell is that it’s one actual specific person’s voice, not a piecing-together of synthetic phonemes. It then picks up an additional thick “technological accent” through the heavy processing of LPC encoding, storage and reconstruction.

### Adafruit AirLift Shield - ESP32 WiFi Co-Processor
Give your Arduino project a lift with the Adafruit AirLift Shield - a shield that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite Arduino-compatible (like the Metro M4 or the classic Metro 328) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in).

### Program in Logo on an Apple II
Long before Python made it easy to start programming, Logo was the language of choice to teach programming concepts to kids. Most kids in the 80s encountered it on their school's Apple II and spent countless hours using Logo drawing functions to move a cursor (which Logo calls a Turtle) around the screen. Let's take a look at the history behind Logo and see what it looked like by setting up an Apple II emulator.

### Build your own BeBox and run BeOS using Virtualbox
Could your 90s OS boot in 10 seconds, use dual processors, and play multiple video files at once (without stuttering)? BeOS could! First released in 1995, BeOS was way ahead of its time and was almost purchased by Apple to be the basis for OS X. Like most products ahead of their time, it failed, but we can still check it out in a virtual machine.

### Adafruit PyRuler
The first time you soldered up a surface mount component, you may have been surprised "these are really small parts!" and there's dozens of different names too! QFN, TDFN, SOIC, SOP, J-Lead, what do they mean and how can you tell how big they are? Now you can have a reference board at your fingertips, with this snazzy PCB reference ruler. Measuring approx 1" x 6", this standard-thickness FR4, gold plated ruler has the most common component packages you'll encounter. It also has font size guide, trace-width diagram, and a set of AWG-sized drills so you can gauge your wire thicknesses. That's not all, it's even a fully featured microcontroller board! Embedded in the end is a Trinket M0, our little Cortex M0+ development board, and in addition, there's 4 capacitive touch pads with matching LEDs that our code will turn into a specialized engineer keyboard.

### Adafruit 1.3" and 1.54" 240x240 Wide Angle TFT LCD Displays
These displays use 4-wire SPI to communicate and have their own pixel-addressable frame buffer, and can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! They have 240x240 16-bit full color pixels and is an IPS display, so the color looks great up to 80 degrees off axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well. There is also a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

### Adafruit Airlift Bitsy Add-On - ESP32 WiFi Co-Processor
Give your ItsyBitsy project a lift with the Adafruit AirLift Bitsy Add-On; - it's the first add-on for the ItsyBitsy and it lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite ItsyBitsy (like the ItsyBitsy M4) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So let's give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in).

### Adafruit ATECC608 Breakout
Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private keys securely. Once the private key is saved inside, it can't be read out, all you can do is send it challenge-response queries. The ATECC608 is the latest crypto-auth chip from Microchip, and it uses I2C to send/receive commands.

### Adafruit TLV493 Triple-Axis Magnetometer
The TLV493D 3-axis magnetometer is a great little sensor for detecting magnets in 3D. In fact, the manufacturer Infineon suggests it could be used to make a joystick! You could also use it for other cool things like detecting objects with magnets attached, like the lid of a box, or maybe a statue that unlocks your secret lair when placed on your mantle?

The TLD493D excels at measuring nearby magnetic fields in three dimensions. It's not going to make a good compass, it's not sensitive enough to pick up the Earth's magnetic field, but you can use it to track the movement of nearby magnets in three dimensions.

### Adafruit PCT2075 Temperature Sensor
The PCT2075 by NXP is a pin compatible drop in replacement for a very common I2C temperature sensor, the LM75. Compared to the LM75 however, the 11-bit ADC in the PCT2075 provides more precise measurements when compared to the LM75's 9-bit ADC. Additionally because the PCT2075 allows the address pins to work in three states (high, low, floating), you can have 27 PCT2075s on the same bus as opposed to the LM75's 8!

Otherwise the two sensors are the same. The PCT2075 will report temperature and allow you to a set a high temperature threshold that the sensor
 will compare to the current temperature and raise an alert when the current temperature exceeds the threshold. There are also a few (metaphorical) knobs to twist to change the alerting and measurement behavior.

The PCT2075 is a handy and inexpensive temperature sensor that does one thing well. Try adding on to your project and have it keep an eye on the temperature and let you know when things get hot.

### CircuitPython NeoPixel Library Using SPI
This hack takes advantage of that faster speed to "synthesize" the NeoPixel data signal on the SPI's MOSI pin. In its most simple form, the hack turns every bit of NeoPixel data into a specific byte in the SPI data. There only two bytes that matter - one that represents a NeoPixel 0 bit, and one that represents a NeoPixel 1 bit.

### Understanding USB Type C: Cable Types, Pitfalls and More
“USB” or Universal Serial Bus is a standard that was created as a means to make connectors more universal and transparent. USB C is a specific shape of USB connector and was designed to take that universality a step further by being the one connector for almost anything including data, power/charging, video and audio. The connector is also reversible, it has no up or down orientation! While USB C does make some things a lot easier, there is also lots of confusion and uncertainty surrounding it.

### LIS3MDL Triple-axis Magnetometer
Sense the magnetic fields that surround us with this handy triple-axis magnetometer (compass) module. Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields. This sensor tends to be paired with a 6-DoF (degree of freedom) accelerometer/gyroscope to create a 9-DoF inertial measurement unit that can detect its orientation in real-space thanks to Earth's stable magnetic field. It's a great match for the LSM6DSOX from ST!

### Introducing Adafruit CLUE
Do you feel like you just don't have a CLUE? Well, we can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board. We wanted to build some projects that have a small screen and a lot of sensors. To make it compatible with existing projects, we made it the same shape and size as the BBC micro:bit and with the same edge-connector on the bottom with 5 big pads so it will fit into your existing robot kit or 'bit add-on.

### Blinking an LED with the Zephyr RTOS
Sometimes, platforms like Arduino or CircuitPython just aren't enough for a high-performance project. This tutorial walks through the setup of Zephyr, an open-source Real Time Operating System (RTOS) backed by the Linux foundation. An RTOS is like a very tiny version of the OS that runs on your desktop or laptop computer, built for tiny embedded chips that need to do intense signal processing or run many processes at once. In this example, you'll be using Zephyr's built-in setup and build tools to create a basic application that blinks an LED on the STM32 Feather Express board from Adafruit.

### Adafruit LPS25 and LPS22 Barometric Pressure and Temperature Sensors
I've got news for you: we're all sitting at the bottom of an ocean of nitrogen, oxygen, and other gasses. Just like a whale would have trouble breathing if it weren't under an ocean of ocean water, we would have a hard time getting oxygen and nitrogen into our lungs if we weren't swimming in it. Because we're used to being under all this air, for us it's relatively normal to us and we don't have a good way of sensing how much there is.

It takes an absolute pressure sensor like the ST LPS25 to tell us how much air we're swimming around in. An absolute pressure sensor can tell you how much gas you're ensconced in, measured in hectopascals (hPa). The absolute part means that it is compared to the absolute vacuum of space. At sea level, the official pressure level is 1013.25 hPa! That's a lot of Pascals!

### 74HC595 Shift Register
These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins. You can chain them together so putting three in a row with the serial output of one plugged into the serial input of another to make 3 x 8 = 24 digital outputs. You can chain pretty much as many as you want. This makes it easy to control a lot of outputs like LEDs from only 3 digital microcontroller pins.

### Adafruit BH1750 Ambient Light Sensor
This is the BH1750 16-bit Ambient Light sensor from Rohm. Because of how important it is to humans an most other living things, sensing the amount of light in an environment is a common place to get started when learning to work with microcontrollers and sensors. Should we turn up the brightness of our display or dim it to save power? Which direction should your robot move to stay in an area with the most light? Is it day or night? All of these questions can be answered with the help of the BH1750. It's a small, capable and inexpensive light sensor that you can include into your next project to add the detection and measurement of light.

Measuring voltage and adjusting it is what electronics is all about so you won’t get far without friends like the PCF8591 ADC+DAC combo.  Analog to Digital Converters help by measuring an analog voltage and turning it into something a microcontroller like a Metro or Arduino 
can understand. If you’re using a single board computer like a Raspberry Pi, you might not have any other way to measure a voltage because even though they are well equipped for digital circuits, many boards of that type don’t have any pins that can measure analog voltages. 
Adding a PCF8591 to your electronics project will give you not one, not two but four analog inputs that you can use to measure voltages from. If knobs are just the thing to complete your project, just add a PCF8591 and some potentiometers and you’re ready to twist, turn, twiddle and tweak to get things just right

### PyRuler Video Conference Panic Buttons
Like most people, I'm doing a lot of video conferencing these days, and sometimes, while working from home, life happens and we need to quickly mute and cut the video feed. Every video conferencing application has a different set of hotkeys and a different UI location for turning this off, and it's not always easy to remember them or find the location, especially in unfamiliar apps. This project turns a PyRuler into a set of 'Panic Buttons' that toggle the microphone and camera in four of the most popular applications.

### Adafruit ST25DV16K I2C RFID EEPROM Breakout
This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C. The tag shows up as an ISO/IEC 15693 (13.56MHz) chip which is readable by phones and tablets. This could be interesting in situations where you want a  tag that can be re-written dynamically when connected to a controller. According to the datasheet, one can even use it as a 'I2C to RFID' transfer system to wirelessly send and receive data from mobile devices (you'll need to write a custom app for that kind of project, though).

### EMC2101 Fan Controller and Temperature sensor
The EMC2101 from Microchip/SMSC is a 1 degree C accurate fan controller with temperature monitoring and it will take care of all of that for you. Those extra pins allow you to set a the speed of the fan, and in the additional pin of a 4-pin connector adds a tachometer output that allows you (or the EMC2101) to monitor the speed of the fan to make sure it's working as expected. In addition to allowing you to control a fan, the EMC2101 includes an internal temperature sensor, as well as connections for an external temperature sensing diode. If you use an external temperature sensor, you can even configure a look up table (LUT) that allows you to set different fan speeds depending on the temperature, and the EMC2101 will automatically adjust the speed depending on the temperature.

### Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor
The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies and more.

### Adafruit SPI Flash SD Card
This breakout is for a fascinating chip - it looks like an SPI Flash storage chip (like the GD25Q16) but its really an SD card, in an SMT chip format. You can wire up like an SD card breakout and use the SD card libraries you already have for your microcontroller. For example, you can use the built in SD library in Arduino, or for CircuitPython we have an sdcard library. The breakout will act just like a 512 MB sized card with FAT formatting (it's pre-formatted).

### Improve the Low Speed of Brushed DC Motors
Brushed DC motors aren't known for their ability to work well at slower speeds; they prefer to zip and zag. In these motors, there's a little-known slow-motion mode that can be activated with just a couple of lines of CircuitPython code. The secret is in the PWM.

### Adafruit ISO1540 Bidirectional I2C Isolator
Sometimes you'll find yourself with an I2C bus controller on one side, and an I2C bus device on the other and you gotta keep em (electrically) separated. Maybe because one is Earth-grounded, maybe because you've got some funky power monitoring setup, maybe you want to reduce noise. Whatever it is, you can use the Adafruit ISO1540 Bidirectional I2C Isolator to add full electrical isolation between two sides of an I2C bus.

### Adafruit AW9523 GPIO Expander and LED Driver
GPIO expanders work like this: you have a board with some number of GPIO but not enough for your project - maybe you need more buttons or LEDs. You could upgrade to a board with massive number of GPIO like the Grand Central, or you could pop on one of these boards. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them.

### ScoutMakes FM Radio Kit
The ScoutMakes FM Radio Kit provides an engaging exploration of Frequency Modulation (FM) radio. And, thanks to BLE, you can control it from across the room. To build an FM radio receiver, you would typically need several components, including resistors, capacitors, transistors, and an amplifier. But thanks to advancements technology, there are now several single-chip, integrated-circuit (IC) receivers on the market. To make our FM Radio Kit as accessible and easy-to-use as possible, we chose one such chip—the RDA5807M, which is broadcast FM stereo tuner with a fully integrated synthesizer and a powerful low-IF digital audio processor—and we baked it into a PCB that complies with the Feather and STEMMA standards. That chip is programmable by way a CircuitPython library.

### Neo Trinkey Zoom Shortcuts
The Neo Trinkey's capacitive touch pads are perfect for having low profile HID shortcuts right next to your laptop. Here, each pad controls either your webcam or mic's mute status in a Zoom call. When you press and hold both pads, you exit the meeting. The NeoPixels let you know if you're muted by showing either red or green lights. When you exit a meeting, the NeoPixels celebrate by showing the classic rainbow cycle animation.

### Generating AI “Art” with VQGAN+CLIP
Described as “a bunch of Python that can take words and make pictures based on trained data sets," VQGANs (Vector Quantized Generative Adversarial Networks) pit neural networks against one another to synthesize “plausible” images. Much coverage has been on the unsettling applications of GANs, but they also have benign uses. Hands-on access through a simplified front-end helps us develop an understanding to better navigate this future landscape.

### No-Code Room Occupancy Status 
Sometimes it’s hard to tell when a room is occupied or vacant. At Adafruit we have a popular meeting room - however, sometimes, it’s being used and if you want to have a meeting, you have to go somewhere else or wait. How handy would it be if we had a public dashboard to view if the room is occupied? Using a FunHouse, a PIR sensor and AdafruitIO WipperSnapper, it can happen.

### Introducing Feather RP2040 SCORPIO
If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs. When we saw the new “PIO” feature of the RP2040 from Raspberry Pi, we just knew it would be perfect for driving huge numbers of NeoPixels. So we created this board, the Adafruit Feather RP2040 SCORPIO, designed specifically for NeoPixel (WS2812-compatible) control, but also good for various other PIO-based projects that want to take advantage of the Feather pinout with an additional 8 consecutive outputs (or inputs).

### Adafruit QSPI DIP Breakout Boards
To make prototyping and designing with QSPI flash a little easier, we designed these breakouts that convert the wide 8-SOIC packages to a cute 0.3" wide DIP. They're available with 16Mbit, 64Mbit and 128Mbit size chips. We find these handy when testing out different flash sizes, or if we just want to add more storage memory to a project.

### Adafruit SPI FLASH Breakouts
If you just need a megabyte or two of extra storage for a project, we recommend an Adafruit SPI FLASH Breakout. The breakout is single-channel SPI only, but it comes with level shifting so it can be used safely with 3V or 5V power and logic. You can address them as a flat memory space or, if you like, format them with a filesystem like littleFS or FAT.

### 3D Printed Light-Up Kaleidoscope
Wireless LEDs glow mysteriously without any obvious power source. Embedding them in translucent 3D printed shapes and viewing them in a kaleidoscope's mirrored interior multiplies them in endless reflections. The source of their power, a slim inductive coil, is cleverly hidden in an attached, rotating base, allowing the illuminated shapes to slide around freely, forming dynamic, colorful new patterns with the slightest movement.

### Adafruit NeoDriver - I2C to NeoPixel Driver
We often get folks asking how to get NeoPixels working on some OrangeBananaOnionRockchipAllWinner Pi type board, given we have our Blinka library that provides support for CircuitPython libraries including the NeoPixel library. A quick solution is this seesaw-based NeoDriver board here: send it the NeoPixel data you want to write over I2C and it will blit out the perfect pixel timing on the other side. We're using an ATtiny1616 so we have enough RAM to buffer a 512-pixel long strand.

### Adafruit I2C Quad Rotary Encoder Breakout
The I2C Quad Rotary Encoder breakout allows you to read up to 4 encoders for big builds with lots of twisty interfaces. You can solder in any four 'standard' PEC11-pinout rotary encoders with or without a push-switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C.

### Adafruit PC Joystick to seesaw I2C Adapter
This board has a 15 pin D-Sub socket port, that you can plug any classic PC joystick into. Onboard is a ATtiny816 helper chip that acts as a I2C peripheral using our 'seesaw' library. Two STEMMA QT ports mean you can plug this board in using a 4-pin JST SH cable to any microcontroller or microcomputer with I2C support and read the joystick X & Y plus the two buttons, even if your main chip doesn't have analog inputs. There's even a 5V power generator on-board since joysticks are expecting that voltage.

### Adafruit STEMMA Piezo Driver Amp
Piezos make noise when you put an AC voltage across them: and the bigger the voltage used the louder they are. We found the nifty PAM8904, which is an amplifier specifically designed for driving piezo elements. We whipped up a quick breakout in our 2mm JST-PH STEMMA form-factor to make it easy for anyone who wants to beep their boops very loudly.

### Adafruit HUSB238 USB Type C Power Delivery Breakout
The HUSB238 USB PD sink chip is neat in that you can either use jumpers (really, resistor selection) to set the desired PD voltage and current or you can use I2C for dynamic querying and setting. We've built a nice Adafruit USB Type C Power Delivery Dummy Breakout board around the HUSB238 to make it very easy to configure and integrate without having to solder any tiny resistors.

### Adafruit VCNL4020 Proximity and Light Sensor
The VCNL4020 is a handy two-in-one sensor, with a proximity sensor that works from 0 to 200mm (about 7.5 inches) and light sensor with range of 0.26 to 16,000 lux. As with all of our new I2C sensors, we've taken the VCNL4020 and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (Feather/Raspberry Pi) or 5V (Arduino/ Metro328) logic levels. Since it speaks I2C you can easily connect it up with two wires (plus power and ground!).

### Adafruit LTC4316 I2C Address Translator
The Adafruit LTC4316 I2C Address Translator does on the fly I2C address translation. There's an 'input I2C' half, and an 'output I2C' half. And any devices on the 'output' half will automatically have their addresses translated from the input half. Specifically, each device will have bit A6 flipped (most-significant-bit of the address) and then bits A4 and A5 can also be flipped or kept the same, with the two DIP switches on board. To determine the translated address, we use XOR bitwise math.

### Adafruit STEMMA Reflective Photo Interrupt Sensor
An optical reflective sensor is a composite electronic device with two elements - an IR LED and an IR photo-transistor. The IR LED blasts light, and when something bounces the light back to the photo-transistor, the transistor turns on and the amount of current flowing through it increases. This makes the sensor great at detecting when something is in front of the sensor.

### Pico W YBox3
A little over a decade ago, the YBox2 Kit was all the rage. It used a Parallax Propeller chip with Ethernet to connect to the Internet and display custom widgets via a composite video output. Years later, it felt like it was time to revisit this project concept with new hardware. The next generation YBox, the YBox3, uses a Raspberry Pi Pico W to run Arduino code that connects to WiFi and displays custom widgets via DVI output with a DVI PiCowbell.

### Adafruit ESP32-C6 Feather
The ESP32-C6 is Espressif's first WiFi 6 SoC integrating 2.4 GHz WiFi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. We took our Feather ESP32-S2 and swapped out the 'S2 for a C6. Plus some re-routing and here's what we've got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage.

### ScoutMakes DRV5032 Hall Sensor
This is a breakout for the Texas Instruments DRV5032 Digital Magnetic Hall Effect Sensor. It is the perfect way to add proximity sensing to your project. The sensor has a digital output that indicates when the magnetic flux density threshold has been crossed. The device integrates a Hall effect element, analog signal conditioning, and a low-frequency oscillator that enables ultra-low average power consumption. By operating from a 1.65-V to 5.5-V supply, the device periodically measures magnetic flux density, updates the output, and enters a low-power sleep state. The breakout comes with a 3-pin header for breadboard use. This board has a simple plug-and-play JST PH (2mm pitch) 3-pin input connector for solderless use. This cable is sold separately and is not needed to use the board.

### Adafruit RP2350 22-pin FPC HSTX to DVI Adapter
If you want to try out HSTX to drive an HDMI monitor or display, this dongle is what you need to take HSTX out and give you a connector with proper level shifting and signal conditioning. Simply connect a 22 pin FPC cable between the Feather RP2350 and Adafruit RP2350 22-pin FPC HSTX to DVI Adapter for HDMI Displays then load DVI output code. In CircuitPython, we have support for 320x240 pixels at 16-bit color, which gets pixel doubled to 640x480. Or, if you're willing to cut some colorspace to save RAM, you can get true 640x480 resolution at 4 / 8 bit color, or 1 / 2 bit grayscale.

### Creating Custom LED Animations
CircuitPython makes it easy to connect with NeoPixels and other RGB LEDs, the most basic way to get blinking is simply setting the color(s) and then sleeping for some period of time before changing the color(s). That works great if you're project isn't doing other things that the sleep will interrupt, for instance blinking even more strands or subsections of LEDs in a different pattern or animations. The Adafruit LED Animation library solves this problem by giving us a non-blocking way to integrate LED Animations into our projects.

### Adafruit LPS28 Pressure Sensor
The Adafruit LPS28 (LPS28DFW) Pressure Sensor is unique in that it can handle a much higher range of pressures: almost every other sensor we've encountered tops out at about 1260 hPa. That means they're totally fine for measuring altitude for most human endeavors, we tend to stay above sea level. However, for some scientific or deep-water uses, 1260 will not cut it! That's why we're happy to stock a sensor that can go down to 4060 hPa - that's as low as -43,000 feet below sea level in air or 40 meters underwater.

### Adafruit TMC2209 Stepper Motor Driver Breakout Board
The TMC2209 makes driving steppers easy-breezy and super-silent. All you need is two output pins, no timers, PWM or real-time microcontroller. Set the DIRection pin high or low to set the spin orientation. Then toggle the STEP pin to take one microstep at a time. You can set whether you want to go faster with 1/8 microsteps, or increase the precision to 1/16, 1/32 or 1/64 microsteps per STEP toggle.

### Chip's Challenge on Metro RP2350
This guide goes over making a recreation of Chip's Challenge that was originally part of Windows Entertainment Pack 4 on Windows 3.1, but completely written in CircuitPython using some of the techniques that were used to make the game run as fast as possible. Some of these techniques include working with 256-color bitmaps, using bitmap tools, handling keyboard input through the console, dialog boxes, and partial screen update tracking.

### USB to Eurorack Power Supply
When the TPS65131 Split Power Supply breakout was added to the shop I thought one thing: Eurorack! Eurorack synthesizers use +12V and -12V for their power input. This can be tricky to accomplish with the usual DIY tools at our disposal, thus this project: a simple 5V USB to standard 10-pin Eurorack power supply. Perfect for quickly testing a module or using a module outside of a usual rack setup.

### Using a Mouse with USB Host
USB Mice are things that we often take for granted while working on devices with a full OS with support for them like Linux on a Raspberry Pi, or Mac / Windows on a PC. Using a USB mouse with a microcontroller requires a more deliberate effort to find and connect to the device, and then read and interpret data that it sends. This guide covers the steps necessary to use a USB Mouse with CircuitPython and Arduino.
