More Arduino fun on Sunday

What better way to spend a Sunday afternoon than to debug some code in your project.
Got around to hooking up the Adafruit LCD display via I2C bus to save some connections,
and also got rid of the garbled text when load was applied to the relays (a 10uf cap did the
trick). In addition I also solved the reset issue when rotctl re-connected (another 10uf cap)
and now need to figure out where some of the weird readings come from and how to make
the buttons work for manual control. Progress is being made.
