Arduino Tutorial 35: Understanding How to Use a Stepper Motor

In this lesson we give you several examples of how to connect and program a stepper motor. Stepper motors are useful because they can produce very large torque at low RPM and are capable of extremely precise positioning. They are somewhat tricky to use, and you must be careful to not try and power them from an Arduino. Arduino can control stepper motors, but they must be powered from an external power supply.

If you want to follow along at home, you can order the Arduino Kit we are using HERE.

This is the code that allows you to toggle the direction of the stepper motor by pressing a pushbutton. The video shows all the details and how to connect the motor up.
