In this tutorial we are going to program the Arduino in such a way that we can turn the potentiometer connected to pin A0 and control the direction of the Stepper motor.
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.
This time we’ll swap out the rotary encoder with an ordinary potentiometer and use that to control either the position or speed of the stepper motor. We will use the code in the previously mentioned blog post as a base and do some alterations to achieve the desired behaviour.
