8.8.2 Bluetooth Controlled Car
1) Description
In the previous projects, we have combined the sensors and robot shield to make the specific function car. In
this project, we use the shield’s motor driving circuit and Bluetooth module to build a Bluetooth controlling car.
How does it work?
Connect well the Bluetooth module using phone’s APP, when the Bluetooth module receives the characters sent
by APP, it will control the motion state of robot car based on the received data.
2) Programming Thinking
1 When your phone’s APP is connected to Bluetooth module, the built-in LED matrix on the micro:bit main
board should show the heart shape. If connection failed, it will show a smile face.
