Hi Garage Nut
I have posted the code on HMT (above).......... I am more than happy for members on HMT to rip the code apart and tell me how I could improve or made it better. I feel the programming is as messy as the wiring in the control box but it does work.

I do not have the time to go through your code in detail, but my initial impression was that the Mega code was very long for the tasks. I might think differently if I waded through it all.

You last function "software_Reset()" is defined but a search did not find any instances of it being called.

The posted Nano code looks to be missing a chunk. As posted it does nothing.
You attach an interrupt "attachInterrupt(0, runEncoder1, RISING );" but there is no "runEncoder1()".
