Play Music Through the BBC microbit Cable
This is exactly what it sounds like. This cable opens up the ability to make music through programming the BBC micro:bit. It has a simple 4mm banana plug connection to the micro:bit and a standard 3.5mm jack connection for connecting headphones or speakers.
It works by programming the micro:bit to turn the speaker on and off and at a specified frequency to create a note. See the enclosed instructions manual that comes with the cable for the frequencies required to make each individual note.
