Fun little demo project using a Micro:bit as a Bluetooth media control remote. It doesn't play music, it controls your computer / phone. Note: this works, but is really a basic tech demo for students to extend and explore. Opportunities include adding other features, using other fun sensors, adding a power switch or rechargeable battery, adding lights, etc
