Below is the breadboard circuit diagram. It’s pretty final. I hope to clean it up a bit when the project is final.
The major additions in this rev is that I’m using transistors against the Arduino digital outs to control the AC relays and a corresponding LED indicator. The on/off switches in those circuits provide a bypass to turn on the AC switches if necessary.
I started with an Arduino Uno R3. Added an RTC shield to it and then another proto shield to add the Nokia LCD level shifter and the i/o headers for the sensors and AC controls. Pics below. All pretty standard stuff. I’ll post the code later.
