The boards look great. Itead did a great job and I got them quite a bit faster than I expected. Unfortunately, I made an error. I managed to, rather than connect to a signal pin on the Atmega, connect the circuit to open the relay intended for the motor controller to a VCC pin. There are 2 extra digital pins free that I left solder points for. I’ll be able to cut a trace and solder on a jumper wire for the time being. I fixed the error in Fritzing and after looking it over for the next couple of days, I’ll order another set of boards.
The Pro Mini I have running has needed reset a couple of times this week, but the old computer controller needed rebooted every couple of days as well. But if I get a call about the splashpad not working, with the arduino, I have no problem saying unplug and plug it back in. 2 seconds after that everything is back in operation.
Update: The controller got stuck again repeatedly. I looks like the problem was being caused by the wires for the input pin from the motion sensor relay being too close to the 24VAC solenoid wires. I re-positioned the wires and have not had an issue since.
