One more thought. I do have a couple of Arduino's, but I am just starting on C for the controller. Does anyone have a link to folks that have posted the code for doing the above crossing control with delays using an Arduino?
By the way, my friend in crime with the 3-D printer, modified some existing Arduino code to drive a stepper motor for my turntable. It has 18 programmable positions (9 forward & 9 reverse). We installed a limit switch and upon power up, the 'bridge' rotates till it hits the limit switch, stops, backs slightly, and then hits again slowly--that is zero position. Then any (of 9) button pushes sends it to that position. If the reverse button is pushed 1st, the next button sends it to 180 deg from the selected position. I would post the program if anyone has a use. Also, if someone has crossing control code, my friend might be able to modify it for my application.
