Arduino+Sparkfun Heating Pad?

I recently bought 2 sparkfun heating pads and a NexxTech voltage regulator +5VDChttp://www.flickr.com/photos/94589858@N06/sets/72157633296011815/
Sparkfun Heating pads:Heating Pad - 5x15cm - COM-11289 - SparkFun Electronics
I am a complete noob at arduino so I have no clue what the code would be to program the arduino to work with the heating pads or even if the voltage regulator will work, so does someone know if this will work and if so, how would I set it up and program it?
Thanks!
