How to Control Stepper Motor using Potentiometer and Arduino
Stepper motors are increasingly taking its position in the world of the electronics. Starting from a normal Surveillance camera to a complicated CNC machines/Robot these Stepper Motors are used everywhere as actuators since they provide accurate controlling. In this tutorial we will learn about the most commonly/cheaply available stepper motor 28-BYJ48 and how to interface it with Arduino using ULN2003 stepper module.
