RGB LED (2 in pack)

RGB LEDs (Light-Emitting Diodes) allow us to toggle the embedded colours of Red (R), Green (G) and Blue (B) in various configurations, allowing us to combine and produce additional colours of Magenta (Purple), Cyan (Turquoise) or Yellow (Amber). When all RGB are turned on at the same time, their combination produces a White colour light.

In other words, with a single one of these, you can set it to 7 different colours of your choice! Add some PWM control and you can even fine-tune these colours further. Available in Common-Cathode (CC) and Common-Anode (CA) types.
