Master Stepper Motors: Control Speed & Direction with Arduino and a Potentiometer! Ever wondered how to control the speed and direction of a stepper motor with just a twist of your wrist using a potentiometer? In this Arduino stepper motor tutorial, I'll guide you through the entire wiring process so that every connection is crystal clear - from how to connect your stepper motor to the right motor driver and then to an Arduino Uno as well as adding a potentiometer to the circuit. Then I'll break
