micro:bit radio

Summary

The BBC micro:bit allows for wireless communication using radio waves. With an antenna on the board, it can send and receive messages between devices. Users can program micro:bits to transmit or receive messages and send a response. To avoid interference, micro:bits can be grouped, allowing communication exclusively within that group. This feature can be used for multiplayer games, messaging between friends, or even tracking pets, offering endless creative possibilities for wireless communication and interactive projects.
