You can use your micro: bit for all sorts of unique creations, from robots to musical instruments and more. At half the size of a credit card, you will be surprised at the amount of hardware each board is equipped with, including 25 red LED lights that can flash messages. There are two programmable tactile buttons and a touch-sensitive logo that can be used to control games or pause and skip songs on a playlist.
The micro: bit can even detect motion and tell you which direction you’re heading. It can also use Bluetooth Low Energy (BLE 5.0) to interact with other devices and the Internet.
