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!
Available in both clear and diffused variants, the diffused variant will appear dimmer but have a wider viewing angle
Update: As of January 2018 we've moved to new supplier for these LEDs and so can now sell them in packs of 5!

Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
