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
I did this project as an IoT-Tuesday project and livestreamed it on Youtube, you can watch it here:
(It turns out the SSL failure on ESP8226 is a timeout not an encryption issue, so you can also do this project with an ESP8266!)
I wanted to make something simpler, all-in-one, using a Feather ESP8266 or WINC1500. In the end, the Feather M0 ATWINC1500 & ESP8266 worked best, since you need to have an SSL connection to twitch.tv but at least you dont need any OAuth or API keys!
