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! These LEDs are diffused,
so they''ll appear dimmer,
but have a wider viewing angle.
