After a lot of work and trials over the past several days I finally got the Mozart 2 controller taking commands from the Honeywell WiFi thermostat and sending out IR signals to the AC across the room. I finally ended up hooking the current sensor up to the ADC 0 input and programmed the Arduino to measure the pin voltage. This is working well. I eliminated the state machine and used a simple timer to hold off retry cycles if the AC toggle did not activate or de-activate the AC box. I caulked the new trim work but did not paint since the wood was still wet. Joined Esquires today by filling out the application and sending a check for $100. We went to amalgamations class at 7:15 but Andy didn't show up, only Jennifer. Duchess and Gustavo came as we were on the way out. We went back in and hung around a while trying the Rumba bronze routine. After a while we finally got it figured out. Before class dinner was spaghetti with tomato sauce and cheese. We had yogurt for dessert after we came back from our non-class.
