RGB LED ( Common Cathode - Clear), These LEDs have four pins - Cathode is the longest pin. One for each color and a common cathode. Use this one LED Cathode for three status indicators or pulse width modulation all three and get mixed colors.
Note: As of 1/2010, the pins in the datasheet are correctly labeled. Pin 3 is Green and Pin 4 is Blue. Those purchased prior to then will have Blue on Pin 3 and Green on Pin 4.
RGB Common Cathode LED makes some beautiful colors with this 10mm tri-color LED with separate red, green and blue LED chips inside! They make a nice indicator, and fun to color-swirl. We like RGB LEDs because they color mix inside instead of appearing as 3 distinct LEDs. To light up a common cathode RGB LED, you will have to connect its common terminal to the negative terminal of the power source. If you want to use these RGB LEDs with your Arduino project, then you will need few components like resistors, jumper wires and breadboard
