/* Simple step test for Pololu stepper motor driver carriers
This code can be used with the A4988, DRV8825, DRV8824, and
DRV8834 Pololu stepper motor driver carriers.  It sends a pulse
every 500 ms to the STEP pin of a stepper motor driver that is
connected to pin 2 and changes the direction of the stepper motor
every 50 steps by toggling pin 3. */
