Moon Patroller

SMARS modular robot driven with 28JYB-48 steppers. When switched on it will slowly crawl forward until blocked at which point it will reverse drive the left track to turn left and then proceed forward again. Yeah it's a super simplistic program but, it does use the standard Arduino [Stepper](https://www.arduino.cc/en/Reference/Stepper) library and interrupts to handle the ultrasonic sensor. Color scheme and name are tributes to [Moon Patrol](https://en.wikipedia.org/wiki/Moon_Patrol).
