Each pulse advances the motor by one step or by a fraction of a step, the latter is known as “microstepping” and will be explained shortly. Unlike DC motors stepper motors are controlled by applying pulses of DC electricity to their internal coils. If your digital camera has an autofocus or remote zoom feature chances are a stepper motor is being employed to do that. They are used in 3D printers to position the printhead correctly and in CNC machines where their precision is used to position the cutting head. They are very useful when you need to position something very accurately. Stepper motors are DC motors that rotate in precise increments or “steps”. So follow along, I promise to take you through all of this “complex” stepper theory one step at a time! Stepper Motors In this article, I hope to dispel that myth by showing you just how easy it is to use a stepper motor with an Arduino. Yet despite their popularity, many experimenters shy away from using stepper motors as they seem to require complex hookups and code. Stepper Motors are used in a wide variety of devices ranging from 3D printers and CNC machines to DVD drives, heating ducts, and even analog clocks. In this article, I’ll show you all you need to know to get started with stepper motors. Learn how to control bipolar and unipolar stepper motors with an Arduino using drivers like ULN2003, L298N, and A4988. 10 Demo 3 – Bipolar Stepper with L298N H-Bridge.9 Demo 2 – Two 28BYJ-48 Unipolar Steppers with ULN2003. ![]() ![]() ![]() 8 Demo 1 – 28BYJ-48 Unipolar Stepper with ULN2003.
