Arduino+Sparkfun Heating Pads?

I recently bought 2 sparkfun heating pads and a NexxTech voltage regulator +5VDChttp://www.flickr.com/photos/94589858@N06/sets … 296011815/

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!

According to the heating pad video (and comments) this pad draws ~0.7Amps at 5V.

The Voltage regulator you linked to is a 7805 that can source 1.0A. So this will power the heating pad.

However, you MUST provide a heat sink on the 8705.

What will be the input Voltage to the 7805 regulator? The heat it dissipates will be (Vin - Vout) * current(Amps) = heat(Watts).

How do you want to control the heating pad from the arduino? Simple On/Off?

This will require a switch controlled for an output pin (just like turning an LED on/off so use the same code as in one of the arduino lessons/tutorials).

Unlike turning an LED on/off the heating pad will need a transistor switch. The subject has been discussed many times in the forums so do a search and read.
