Okay..so I just got my arduino duemilanove and RGB led pack. 
. I am not at all into programming and want the arduino to control a single rgb led and change its colour randomely. 
. Please give me a code and pn configuration for this project and i would be so thankful. Please Help....!
HELP NEEDED !
Look in playground "LED Lights and Displays":

Assuming you have a common anode RGB LED.
Wire up like it is shown here.
Then use
analogWrite(9,redValue);
analogWrite(10,greenValue);
analogWrite(11,blueValue);
Where redValue, greenValue, blueValue, are all variables with the values between 0 and 255.
Note a value of 0 will be full bright and a value of 255 will be off and a value of 128 will be half way bright.
