Automatic Twitch On-Air Sign: We’re doing a lot of streaming lately, and I wanted to make a sign that would let people know when we’re on air. All this guide will do is connect to the Twitch API and determine if the user is currently streaming – if so, the Feather will turn on some NeoPixels (you can also just use LEDs if you like) to light up the sign. You can easily extend this to, instead of parsing for a live stream, display the stream name, number of viewers, game-being-played or anything else available from the Twitch API. Read more.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
