Controlling two or more Stepper motors with three pins using a 595

Courtesy/Thanks to: Anything Arduino

Description: In this episode we free up some pins on the Arduino Bumper Robot that we built in the earlier episode. By using a 74HC595 and rewrite the code a bit only three pins are used for both motors instead of 8 before.
