Reply to "The RR Track Signal Control Board Project"

I was thinking of a simple input and output logic signal to daisy chain the boards.  Since I've pretty much decided that in order to be flexible that it would have to be uP based, that should be pretty easy to provide for.

My current thinking (when I get time to think about this), is the Arduino Nano piggybacked on a board with the power supply and driver components.  Using the Arduino allows easy portability of the firmware that is developed and modified along the way.  Also, the Arduino has lots of I/O ports to allow flexibility in what signals it drives.  I'm also thinking at least the provision for one 10A relay so that it could be programmed to control track power if desired based on the signalling input.
