Tutorial: Stepper Motors Controlled with the Arduino
This tutorial was developed for the MAKE course at the University of South Florida (www.makecourse.com). This tutorial discusses how stepper motors work and how they can be controlled with a micro controller like the Arduino. The different stepper modes like full step, hall step and micro stepping are discussed. Transistor based electronic stepper drivers are explored. A simple Arduino sketch is explained, which allows the direct experimentation with stepper motors. The sketch and a modified stepper library for driving a 28BYJ-48 stepper motor can be found on makecourse.com."
