Does anyone have a schematic on how to wire up a RGB LED and Piezo Element with an Arduino Uno? What I'd like to do is illuminate different colors on the RGB LED which activates a different sound out of the Piezo.
For example:
When RGB LED is RED (0xFF0000) the Piezo produces "jingle bells"
When RGB LED is GREEN (0x00FF00) the Piezo produces "deck the halls"

It is not clear what exactly what you want to do.
What turns on the LEDs? Can the same thing not trigger the sound?
Do you want to detect the colour of the LED and then trigger the sound?
I will trigger the LED by sending controls through the serial port. The problem I have is wiring up the circuit. I can't figure out how to wire it up correctly. Here is what I have:
Arduino pin #9 to Piezo Element
Arduino pin #9 to 330 ohm resistor to red pin of RGB LED
Arduino pin #10 to 330 ohm resistor to green pin of RGB LED
Arduino pin #11 to 330 ohm resistor to blue pin of RGB LED
The problem is Arduino pin #9 is trying to control the Piezo element and the red pin of RGB LED. If I run the LED with out the Piezo it works, if I run the Piezo without the LED it works. But they don't work wired together as stated.
You mean a bit like this guy?
But they don't work wired together as stated.
No they won't and they never will, you need to use a different pin for each thing you need to control.
So use another pin.
Then have the routine that triggers the LED to light also call a function to play a tune with the tone pin.
