4.1.3 1.3 Turn the Wheel
A motor is a typical digital output device, and it is used in the same way as an LED. However, the motor needs to be
driven with a large current, and the large current may damage the main control board such as R4 board. Therefore, an
motor driver module is used in this occasion, which is a good helper for the R4 board to control the motor safely.
