Stepper - Arduino Sketches: Tools and Techniques for Programming Wizardry - page 260

Summary
In this chapter, you have seen what a stepper motor is, how and where it is
used, and how to control one with an Arduino. The example has given you an
idea of how easy it is to use a stepper motor, and how you can use them in your
own applications. In the next chapter, you will see the Firmata library, a control
library that lets you read and write Arduino pins directly from a computer.
