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. Radio is a way of sending and receiving messages and BBC micro:bits can use radio waves to communicate with each other.
On the bottom edge of your BBC micro:bit there are 25 gold strips, called pins. These pins allow you to really get creative. You can create circuits, connect external things like buzzers and motors and make your own fun projects.
