This 5mm RGB LED contains three LED elements (red, green and blue). Each element can be controlled independently. By varying the amount by which each element is turned on any colour can be created. They are ideal for design colour controlled lighting effects.

This LED has a common anode which is the longest leg (positive).

Question:

So if I was wiring a large number of these into a circuit, how would I change their colours? Would I use a microcontroller, or change the voltage?

    The way you control the colour is by controlling the voltages across the three LEDs. You need to control the three voltages independently so a microcontroller is a good idea, it would be possible to do it manually with some variable resistors though.
