Introduction: 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.

Step 1: Tutorial
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.
Step 2: Hardware Required
Hardware Required :
- 10k Potentiometer
Step 3: Circuit & Connections
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.
