Radio and pins
Take your micro:bit programming to the next level using radio and pins
Your micro:bit can communicate wirelessly with other micro:bits using radio. These projects and videos will get you started using radio to send messages and make multi-player games. You’ll also learn how you can use your micro:bit's pin connections to make sound and create your very own micro:bit guitar.
Each set of projects is designed to progressively build your understanding and confidence. In set 1 you will learn about radio, in sets 2 and 3 you’ll work with the pins.
Set 1: Sending messages
In this sequence of projects, you’ll learn how to use the radio to send a duck image from one micro:bit to another, then create a group game and finally program a simple ‘yes/no’ game.
Set 2: Sound
Learn how to create sound and music using your micro:bit. You’ll need some headphones or a speaker and crocodile clip leads.
Set 3: micro:bit guitar
Make your own micro:bit guitar with the clips, headphones and cardboard. This sequence of projects will take you step-by-step through creating and programming a micro:bit guitar.
