The Kegerator

I'm starting something mildly ambitious for my first real Arduino project. I'll be making a temperature controller for a chest freezer. The net effect will be to be able to switch the freezer on and off based on a "Set temp."

The controller will consist of the following:
  • A temp probe
  • An LCD to show the current and set temperatures
  • Up and Down buttons to set the temp
  • A massive 5vdc/400ma driven 240V/30A relay
  • An Arduino boot-loaded AVR ATMega328
Eventually, I intend to add a lid switch to detect an open lid, an alarm to tell you when the temp is X degrees too high and another temp sensor in the tower to switch on a fan to keep the lines cool when the tower gets too warm.

Pictures and code can be found here:
