Steppermotor controlled by Arduino

This is a short how-to on controlling a bipolar stepper motor by an Arduino and a L298N based dual H-bridge controller board.

For a long time I thought about playing around with a stepper motor. The goal for this page is not to explain what a stepper motor is, but to document for myself What I did so I can reproduce the results at a later time.

The Wiki page on stepper motors does an excellent job at documenting the motor.
