![]() It has 4 terminals, in which 3 terminals red, green, blue, and another terminal represents anode or cathode of LED type. ![]() These are widely used in stage designing, home decorations, LED matrix, displays, outdoor lightings, and in some electronic applications. It can produce any color as output by a combination of 3 colors red, green, and blue to indicate the operation of the device. What is an RGB LED?ĭefinition: The three-colored LED’s like red, green, blue are combined together in one package (one LED) to emit different colors as output is called RGB LED. ![]() This article describes how to generate different colors using the RGB LED. RGB LEDs comes under the Multi-colored LED category. Usage of Multi-colored LEDs in the device reduces, cost, power and emits more than one colored light like red, blue, green, etc when compared to single-colored LEDs. LEDs are widely used in various applications such as in cars, bikes, home appliances, offices, lighting, mobiles, televisions, etc. This indicates whether the electronic device is working or not. In electronic circuits, the LED is a type of PN-junction semiconductor diode, which can emit light when current flows through the circuit in the forward direction. The term LED stands for Light Emitting Diode.
