In making this circuit you will learn how to use the arduino random number function and how to create different colors on an RGB LED.

This is a real simple plug and play circuit where the RGB module plugs straight into the arduino, pin 8 is permanently low making it effectively GND pins 9,10,11 are analog outputs whose intensity changes the intensity of the three colours in the LED in the following manner

Pin 9 is Red

Pin 10 is Green

Pin 11 is Blue
