AdaBox 005
Explore and use the contents of your AdaBox 005
by Tyler Cooper
You've consumed four AdaBoxes - the equivalent of a delicious, nutritious meal of DIY electronics. And now it's time for dessert. Pour yourself some coffee (or a nice cold glass of milk) because it is finally time for Raspberry Pi.
AdaBox 004
Explore and use the contents of your AdaBox 004
by Tyler Cooper
Sit down, strap in, and pump your Feather ecosystem up to 11. The last of our Feather-focused AdaBoxes has all the ingredients for a remote controlled music player, a Zen-inducing meditation machine, or your very own Radio Free Adafruit that streams tunes through the internet.
AdaBox 003
Explore and use the contents of your AdaBox 003
by Tyler Cooper
If walls could talk. If fridges could email. If toasters could tweet. If garbage cans could blog. If sinks could post stories. If stoves could code. The Internet of Things can be in all the things. Adafruit, Digikey, and Nimbus the Friendly Cloud Entity are here to help you learn how to connect everything you need and nothing you don't.
AdaBox 002
Explore and use the contents of your AdaBox 002
by Tyler Cooper
With AdaBox 002, we are bringing you the fun and versatility of a small robot. Learn how to control your new robot friend with a phone and make it sing custom tunes. Learn how to make your new robot more intelligent and independent too!
Adafruit IO Basics: NeoPixel Controller
Control NeoPixels with Adafruit IO sliders
by Tyler Cooper
In this basic example of ways to interact with Adafruit IO, we use an Adafruit NeoPixel ring and control the RGB levels with three sliders on an AIO dashboard.
Wireless Inductive Power Night Light
Nikola Tesla approved!
by Tyler Cooper
Create your own night light that harnesses the power of wireless energy. Change the brightness of the light by moving it away from the power module.
DIY DC/DC Boost Calculator
A calculator for rolling your own basic DC/DC boost with a microcontroller
by Tyler Cooper
For many small projects, its cheaper and easier to DIY a boost converter than to buy a specialty chip. DIY converters are usually not as efficient but they're quick & cheap!
Adjustable Breadboard Power Supply Kit
A very low dropout adjustable power supply
by Tyler Cooper
This project details the design of a very low dropout adjustable power supply. A good power supply is essential to electronic projects. While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs.

All About LEDs
A detailed introduction on how to use LEDs
by Tyler Cooper
This tutorial will cover those wonderful blinky things, LEDs. We're also going to cover how to calculate the current going through an LED and in the mean time introduce two important laws of electronics, Kirchhoff's Voltage Law and Ohm's Law.
USB + Serial RGB Backlight Character LCD Backpack
Control an RGB Character LCD with USB or TTL Serial
by Tyler Cooper
Adding a character display to your project or computer has never been easier with the new Adafruit USB or TTL serial backpack! This custom-designed PCB sits on the back of any 'standard' character LCD (16x2 or 20x4 sized) and does everything you could want: printing text, automatic scrolling, setting the backlight, adjusting contrast, making custom characters, turning on and off the cursor, etc. It can even handle our RGB backlight LCDs with full 8-bit PWM control of the backlight.

DS1307 Real Time Clock Breakout Board Kit
Real time clock mini-breakout board
by Tyler Cooper
This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC, and works best with 5V-based chips such as the Arduino.
Reverse Geocache Box
For proposals, or for fun!
by Tyler Cooper
Adafruit customer Kenton Harris shares how he proposed to his girlfriend using a reverse geocache box. Learn how a reverse geocache box works, and how you can build one for yourself.
How to Make a Pogo Pin Test Jig
Get jiggy!
by Tyler Cooper
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 WebIDE
The easiest way to develop code on your Raspberry Pi or BeagleBone
by Tyler Cooper
The Adafruit WebIDE is by far the easiest way to run code on your Raspberry Pi or BeagleBone. Just connect your Pi or BeagleBone to your local network, and log on to the WebIDE in your web browser.
