Javelin Stamp Application
This program demonstrates basic, full-step control of a unipolar stepper motor using the Javelin Stamp
microcontroller. The Stepper class handles the connection details and contains methods that allow the
programmer to specify the number of steps, as well as the delay (in milliseconds between steps).
