Introduction: Microbit RC of Cricket

You can remote control a Micro:bit and Cricket using another Micro:bit. In this example, we used a transmitter to control LED colored lights and a micro servo to create a fun Rocket League "goalie". Students can use the controller to change the lights and move the goal post to block the ping pong ball.
