A physical disability can make it impossible to operate a touchscreen device such as an iPhone or iPad. Commercially available switch control devices can cost several hundred dollars but with the power of Adafruit Bluefruit BLE devices you can build an interface for a fraction of that cost. We show you how in this tutorial.
Single Step JTAG Debugging is here and stable for the Arduiino. Adafruit's Feather M0 line not only provide 5x the clock speed and 8x the storage of recent Arduino's, but they now have the ability to talk to a debugger. This tutorial will show you how to make a simple FeatherWing PCB and connect to it from MacOS / OS/X.
Here's a Soviet themed launch-code box, complete with missile switch covered toggles, a Feather with red 14-segment display for the countdown timer, and stress-inducing piezo buzzer. Use it for an escape room, prop, or wedding proposal. Your players, or potential spouse-to-be, will need to enter the correct five-switch sequence to defuse the device before all is lost. (Note: this project is a harmless prop, not an actual bomb.)
Bend all audio files to your will with the Adafruit Music Maker FeatherWing! It's a fun-size version of our Music Maker shield for Arduino! This powerful 'Wing features the VS1053, a chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally.
If you've already got an Amazon Alexa or Echo dot in your home or office, you can easily add your very own devices. In this quick project we'll show how to use an Adafruit ESP8266 Feather HUZZAH to control NeoPixels or a relay. You can easily adapt the code to add any number of devices to a single Feather for all sorts of interactive home automation projects with ease!
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.
Spice up your Feather project with a beautiful 2.4" touchscreen display shield with built in microSD card socket. This TFT display is 2.4" diagonal with a bright 4 white-LED backlight. You get 240x320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on
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. This device broadcasts a wireless network without a password. Connect any wireless device to it and once the connection is made the MAC address of the device will be displayed on the small OLED screen.
Build a creepy, glowing test tube display... if you dare. A Feather microcontroller makes the UV LEDs shine to create dazzling effects in the fluorescent pigment-and-water filled test tubes. Easy-to-assemble black iron pipe forms the base of this labware set. The perfect prop for your own haunted house or creepy laboratory.
If you're here, it's because you were given the gift of electronics with an AdaBox! You are a beginner who is getting started with your AdaBox or you just want to relive what it's like being a beginner at electronics again. But most of all, you want to learn how to build and make stuff with electronics!
This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You get both an I2C real time clock (PCF8523) with 32KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS). Tested and works great with any of our Feathers, based on ATmega32u4, ATSAMD21, Teensy, or ESP8266.
Add short-hop wireless to your Feather with these Radio Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x's). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device.
The ESP8266 based Feather HUZZAH & the HUZZAH ESP8266 breakout are both very popular options for connecting projects to Adafruit IO. In this guide we are going to walk through the setup needed to get your ESP8266 up and running with the Arduino IDE & Adafruit IO. This same basic setup can be used as you progress through our Adafruit IO Basics series of guides.
This is the Power Relay FeatherWing. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board. Compared to our smaller Relay FeatherWings, this one can handle a beefy 1200 Watts!
It’s not pleasant thinking about one’s mortality, but that’s the point of this project: to make one aware of the passage of time and how precious each minute is. As you look at the clock, remember that you are never getting those minutes back. Stop watching internet cat videos and make the most of them!
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)
Wireless is wonderful, but sometimes you want the strong reliability of a wire. If your Feather board is going to be part of a permanent installation, this Ethernet FeatherWing will let you add quick and easy wired Internet. Just plug in a standard Ethernet cable, and run the Ethernet2 library for cross-platform networking.
