Tonight I added a RGB LED to the project. The LED turns red when the temp drops too cool (to indicate that the furnace has turned on), and blue when it gets too hot (to indicate the A/C has turned on). When the temp is in our 15 degree comfort range, the LED is green. I'll try to get a pic uploaded tomorrow, and video this weekend. I just put my finger over the temp sensor, and the LED changed from green to blue. Very cool!
