    The BBC micro:bit can use radio waves to communicate wirelessly between micro:bits.
  • 00:00:12
    In order to generate and detect these waves the micro:bit has an antenna on top of the board.
  • 00:00:18
    You can program micro:bits to use this radio feature.
  • 00:00:22
    While one device transmits or sends a message, the other will
  • 00:00:26
    receive the message and can be programmed to send a message back.
  • 00:00:31
    To help avoid interference from other micro:bits also sending messages, you can
  • 00:00:35
    program your micro:bits to belong to a group, then they will only send and
  • 00:00:40
    receive messages to each other in that group. You can send messages to a friend
  • 00:00:45
    or a group of friends, design and build multiplayer games using the radio
