The video shows a stepper motor running controlled by a USBizi .NET MicroFramework development system from GHI Electronics. I use 4 GPIO pins on the USBizi board to control a stepper motor salvaged from an old 5 1/4" floppy disk drive. I have written a simple .NET motor driver class in C#, which takes care of engaging the solenoids in the stepper motor. I have used a ULN2003 integrated circuit as the motor driver.
