You are now going to take a quick look at a new type of motor called a stepper motor. Project 28 is a simple project to show you how to control the stepper, make it move a set distance, and change its speed and direction. Stepper motors are different than standard motors in that their rotation is divided into a series of steps.

By controlling the timing and number of steps issued to the motor, you can control the speed of the motor and how far it turns fairly precisely.
