SM w Switch and LED Blink by uscmlm02

This sketch is missing a short description

This has the Stepper motor driven by EasyDriver fed by outside 12v power source. Board now has 5v regulator to power the Uno. One sensor is wired for stop limiter. Striking the switch will reverse the direction of the motor. There is a built in movement to pull the 'cart' off the switch. Upon striking the switch, the LED will blink to indicate reverse movement. Potentiometer gives a speed adjustment signal, multiplying this by 10 gives a span of speed (via delay) of crawl to faster than needed. Current board is wired with a power interrupt switch, must have this pushed down in order to give power to the motor.
