I have a project that I need to use a transistor as a heating element.
I am new to this so making a circuit from scratch isn't something I can do just yet so i need some help! The circuit will be run on a 5v battery. I need to be able to control the heat up and down im not sure if a variable resistor is something that would be able to do that. it can also drive a led to let me know the unit is on.

If anyone can help me in a simple circuit diagram it will be much appreciated.

This is the Transistor i am using:http://www.maplin.co.uk/p/1a-positive-fixed-voltage-regulator-isowatt220-cr14q
