I just got my Uno today and have been playing with it since I got home from work and I have run into an issue. I am trying to make a multi-colored light using red, green, and blue LEDs.
Now the issue I'm having is that the Green LED will not light if it is the only LED to be lit. I've tested the LED on its own and it works fine but in my "ColoWheel" program it will not light on its own. It will light anytime another LED is on as well, just not alone.
