Tiny:bit is a mini robot that uses a Micro:bit as its brain. To enable this robot to connect wirelessly with the outside world, it’s equipped with built-in Bluetooth. This Bluetooth functions like an “invisible bridge” that connects Tiny:bit to a smartphone, tablet, or even another Micro:bit.

For example, when you want to control Tiny:bit via your phone, you no longer need cables. Simply turn on Bluetooth on your phone, connect it to Tiny:bit, and you can issue commands to move forward, backward, turn, or turn on the lights. Similarly, Tiny:bit can also receive signals from other Micro:bits, allowing one robot to be controlled by a Micro:bit programmed as a remote control.
