			=Overview=

			The RGB LED has three different colors of LED inside of it. Like a pixel on a computer screen, you can control the output of all three lights to create different colors. For example, to make purple, you'd turn on the red and blue LEDs and turn off the green LED.

			=Hello World=

			This is a simple circuit to turn on the LED and cycle through different colors.

			===Breadboard Diagram===

			The following is a diagram of the breadboard layout for our simple Hello World program.
