Arduino Tutorial – Stepper Motor Control with Potentiometer

This tutorial is all about tuning the speed of a stepper motor using a potentiometer. The idea is to up or down the speed of a stepper motor using with analog read. Theoretically analog input to a digital output, we’re going to use this concept to control the speed of a running stepper motor.

 

The Stepper motor used here is a rusty old EPOCH (5 wires) stepper motor, which is a unipolar stepper.

 

Use the analog input with the help potentiometer to control the delay in-between each steps of the stepper motor. Shorter the delay in-between each steps – faster the stepper motor runs and vice-versa.
