Arduino
Arduino code that receives values from Adafruit IO, parses the text, and based on key words, plays music and runs a light animation. There's another file config.h which contains wifi password and adafruit io feed name and key.

I teach math and technology to junior high and high school students at a small project-based school... and I make stuff.
Thanks to Jo Franchetti.
