UPDATE! I finally have a follow up video on how to drive this motor with an Arduino! Check it out at http://aka.ms/28BYJArduino

The sample code from my Arduino video is here:
http://aka.ms/28byjrepo

This video gives a detailed introduction to the common 28BYJ-48 stepper motor, and the ULN2003 Darlington Array driver board. You can use the info from this video to drive the stepper motor with most any microcontroller.

Stay tuned for follow up videos on driving the motor with the Arduino, Raspberry Pi, and possibly others. Meanwhile here are some other great resources:
