Mini Piano Module for micro:bit [Discontinued]

Learn how to code in Microsoft MakeCode whilst also having fun making music! This mini piano module for the BBC micro:bit is a fun way to get to grips with block-based coding and an ideal first add-on.

The board features 13 capacitive touch piano keys, a buzzer and 4 RGB LEDs. You will be able to play the full octave by touching the piano keys, and the RGB LED will display accordingly. You can even change the colour of the LEDs in the code yourself!
