RGB LED

img_rgb

RGB LEDs can emit light in a wide range of colors. Each RGB LED combines three individual LEDs—red, green, and blue—encased in a transparent or semi-transparent plastic shell. By adjusting the input voltage to each of the three pins, different colors are produced through color mixing. In fact, this allows the RGB LED to generate up to 16,777,216 unique color combinations.

RGB LEDs can be categorized into common anode and common cathode ones. In this kit, the latter is used. The common cathode, or CC, means to connect the cathodes of the three LEDs. After you connect it with GND and plug in the three pins, the LED will flash the corresponding color.

Its circuit symbol is shown as figure.

An RGB LED has 4 pins: the longest pin is the common cathode pin, which is usually connected to GND, the left pin next to the longest pin is Red, and the 2 pins on the right are Green and Blue.
