LCC Breadboard Visual

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.

LCC Requirements

The Lizard Climate Control system has these requirements (updated as they change):

  • turn lights and heaters on/off at specified times
  • maintain specified temperatures during day and night
  • report current temperature/humidity both locally (at cage) and remotely via internet
  • manual bypass of Arduino control of AC switches
  • built in fail-safe for over temperature situations
  • protect sensors from lizard and other in-cage hazards
  • visual indication of temperature situation (green=good, red=bad etc)
  • document it!
