 This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).
 
 This code uses the Power Shield to drive up to 6 MOSFETs. You'll need a computer power supply to power the MOSFETs.
 
 The solenoid from SparkFun works with 12V and uses around 650mA when it's turned on.
