Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins - Cathode is the longest pin. One for each color and a common cathode. Use this one LED for three status indicators or pulse width modulate 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. **Features:** * Forward Voltage (RGB): (2.0, 3.2, 3.2)V * Luminosity (RGB): (800, 4000, 900)mcd **Documents:** * [Datasheet](/datasheets/Components/YSL-R596CR3G4B5C-C10.pdf) * [Wiring Example](http://wiring.org.co/learning/basics/rgbled.html) * [LED Tutorial](https://learn.sparkfun.com/tutorials/light-emitting-diodes-leds)
