Arduino and EasyDriver turning a Stepper Motor

One of the great things about Arduino is that whatever you're trying to do, there is a good chance that someone has done it before and posed the code.

Mark Gilbey and I are currently working on my poor man's pick and place 'bot. We'll be moving the head around using some SparkFun steppers, and I liked the look of the EasyDriver Stepper Controller.

The EasyDriver website has an examples page which includes a wiring diagram and sample Arduino sketches. I tried it out and everything just worked.

The motor is turning in micro-steps of 1/800th of a revolution, at a speed of 5000 micro-steps per second.
