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 Tom Igoe's notes on steppers.

Circuits

• Unipolar Steppers
• Bipolar Steppers

Examples

• Motor Knob: Control a highly accurate stepper motor using a potentiometer.
• Stepper One Revolution: Turn the shaft one revolution clockwise and one counterclockwise.
• Stepper One Step At A Time: Turn the shaft step by step to check the proper wiring of the motor.
• Stepper Speed Control: Control the stepping speed with a potentiometer.

Functions

• Stepper(steps, pin1, pin2)
• Stepper(steps, pin1, pin2, pin3, pin4)
• setSpeed(rpm)
• step(steps)
