Reference Stepper Library This library allows you to control unipolar or bipolar stepper motors. To use it you will need a stepper motor, and the appropriate hardware to control it. For more on that, see. Circuits. Examples.: Control a highly accurate stepper motor using a potentiometer.: Turn the shaft one revolution clockwise and one counterclockwise.: Turn the shaft step by step to check the proper wiring of the motor.: Control the stepping speed with a potentiometer.
