Microbit Musical Instrument

I put together a very simple instrument using my BBC Microbit. All you need to do to make your own is download the hex file here to the Microbit then rig it up to a speaker or headphones with a crocodile clip as shown in the diagram below. Pressing the 'A' button makes the tone go up by a single note while the 'B' button makes the tone go down a single note. A value lower than -10 or higher than 10 is automatically set back to 0. 'A+B' plays the note. I advise putting a piece of plastic on the buttons to allow both buttons to be pressed easily at once while still allowing for each button to be pressed individually.
