An RGB LED is actually three single color LEDs (Red, Green and Blue) combined

into a single package. Because of this controlling it is very similar to controlling a

single color LED. The one difference is the 3 LEDs share a common anode (long

lead (+))..: A quick refresher on LED control can be found here tinyurl.com/ :.

Plug the LED into the breadboard then connect the common anode to +5 volts

(5V). Connect a current limiting resistor to the remaining 3 pins. Connect these

resistors to ground (Gnd) to test each color..: IMPORTANT: always use a current limiting resistor with the 3 cathodes :.

Controlling the RGB LED digitally 7 colors are achievable (see the color truth table

below)..: Download a demo program from http://tinyurl.com/ :.

Controlling the RGB LED using the Arduinos PWM pins allows for almost infinite

control of color. For a helping hand see the analog color wheel below..: Download a demo program from http://tinyurl.com/
