Arduino Stepper Motor Interfacing Using Darlington IC ULN2003A In this article, we are publishing a project which explains different aspects of interfacing a Stepper Motor with Arduino. Stepper motor is a specially designed DC motor which comes with advantages of both a servo motor and a normal dc motor. Compared to a normal Dc motor, the maximum rpm a stepper motor can produce is very low. But they have the advantage that they can be positioned accurately. Unlike servo motor, stepper motor can also be rotated continuously. On the basis of the winding arrangement inside, the stepper motor can be categorized into unipolar and bipolar. The stepper motor we are using here is a unipolar stepper motor named 28BYJ-48. After going through the project you can run or turn the motor to desired direction. Let’s begin our tutorial and learn how to interface a stepper motor to Arduino. Objectives of…
