Introduction: Dual PIC Thermometer
The geek inside me has always wanted a fridge that shows the inside temperature for both the freezer and the fridge compartments. However, when we recently replaced our very old fridge we ended up getting a new one without the built in thermometer. So I decided that one of my next projects would have to rectify this problem.
For further information on how I made this, including all details you need to build your own, please see my blog entry @ http://diy.viktak.com/2011/12/dual-pic-thermometer.html
