Small heat source

[Stefan Wiswedel]

Hey all,

So I have my temperature controlled fridge and mash system working pretty well. I still want to work on the software a bit (like maybe using a PID library instead of just turning on and off around a setpoint) but I will get to that later.

In my temp controlled fridge, it would be great to have a small heat source that could warm the inside of the fridge a few degrees. Ideally it would just run off of the Arduino's 5 or 9v supply. The project box I am working in is already VERY tight so not too keen to use another relay and/or power supply..

Any ideas?

A power resistor.  Like a 3 watt unit.
