So I picked up a very nice tricolor led from http://www.superbrightleds.com/. I can't seem to get it wired properly and was hoping somebody could point out my stupidity. Here is a datasheet for the led: http://www.superbrightleds.com/TriColor%20LED.htm
I picked up one of the common cathode versions. Here is a diagram of how I think it should be connected:
When it is connected in this way only the red led lights up when I expect all 3 colors to be on at once. I calculated out all the resistor values, I'm using 1/2Watt resistors but that doesnt make a difference. Help!
