Some years ago I designed and built an auto-reverse controller that is commonly used to send a trolley or other small engine back and forth on a point-to-point line.

I recently revised the program and converted the code so that it would work with a more contemporary microcontroller, the Arduino.

My notes and a video that show the new controller are here:
