Assuming you have a common anode RGB LED.
Wire up like it is shown here.

Then use
Code: [Select]
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.
