RGB LED – 5mm – Common Cathode

The 4 leg RGB LED is an ideal component that can be used in projects that require multicolor displays. A single RGB LED serves the purpose of three individual different colour LEDs. The RGB name stands for Red colour, Blue colour, and Green colour respectively. To produce more colours, the RGB LED can colour mix the three primary colours (RGB) through Pulse Width Modulation (PWM). This component can be easily configured in a common cathode connection, where the ground is connected to the negative terminal and the three other pins are connected to the posiive terminal.
