Arduino?

To control something that draws 'relatively large' power (more than a few milliamps) a transistor switch is cheap & easy, or use a small relay. IIRC the Arduino can sink or source about 20 mA on a Digital IO pin.

The transistor would be the option I would pick. I've worked with transistors in powering a DC motor from a cd drive, so I have some small experience.

So now I know I can handle putting in a cathode.

The question remands what about battery life, would this basically kill off my battery life?
