My buddy Sam Stokes just posted an awesome video on Channel 9’s “The Maker Show” about “Arduino and Servos” at the end of it, he mentioned that if you wanted to know more about steppers motors, you could check out my blog.
About a year ago, I was using some of the 28BYJ-48 steppers motors you can find pretty cheaply online. In order to understand them better I took one apart. That really got my mind going and after quite a bit of research I put together a video that explains how they work, and how you can drive them from pretty much any Microcontroller (like the Arduino, etc). Check it out!
