Arduino security light

My first, basic, arduino (clone, Gizduino) project.

The project uses a green LED and photoresistor. The photoresistor measures the light in the room and turns on an LED for 2 seconds when there's a certain variance in the light reading (e.g someone walking past the sensor, reducing the amount of light it senses). The readings taken from the photoresistor are also sent over Serial to be viewed on the computer.
