Driving a DC Motor

  • Michael McRoberts


Now it’s time to control a DC motor. If you ever plan on building a robot or any moving device, the skills you are about to learn will be essential. Driving a motor requires currents higher than the Arduino can safely provide from its outputs, so you will need to make use of transistors to ensure that you have enough current for the motor and diodes for protection of the Arduino. The hardware overview will explain how these work.
