Arduino Tutorial - Stepper Motor Control With Potentiometer

This instructable is the written version of my "Arduino : How To Control a Stepper Motor with Potentiometer" YouTube video that I've uploaded recently. I strongly recommend you to check it out.

First, you should see the following Instructable:

How to Control a Stepper Motor With ULN 2003 Motor Driver

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.

Hardware Required :

- 10k Potentiometer

connect to

p1 - +Vcc

p2 - GND

p3 - A0 ( analog input )

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.
