![]() The RGB LED with common cathode, potentiometers, resistors, and Arduino Uno board are connected together through jumper wires. The arrangement and design can be done easily. The connection of common anode LED type is shown below: Connect the anode to the power supply’s positive terminal.A LOW or ground signal should be applied for Red, Green, and Blue lead.In order to control every color, the connection should be like below: In this type of RGB LED, the anode part of all the internal LEDs are connected together and this is connected to the lead of the external anode.Let us discuss each of these in detail in the below sections. In regard to this discussion, there are mainly two RGD LED types which are When the light emits, then the lengthy red is considered a common cathode. ![]() In the same way, place the multimeter tip which is black in color on the lengthy lead and the other tip of the multimeter (red-colored tip) on any one of the other leads.When the LED emits light, this indicates that the long lead is a common anode.Put the multimeter tip which is red in color on the lengthy lead and the other tip of the multimeter (black colored tip) on any one of the other leads.Place the multimeter in continuity mode. ![]() These three colors are combined to emit almost any of the desired colors. RGB LEDs consist of three principle-colored LEDs which are Red, Green & Blue. The implementation of this device can be found in many applications like external lighting such as stage, outdoor location, home décor, matrix display, and many others. RGB LED is fundamentally considered an LED package that holds the ability to emit almost any of the colors. Now, this article focuses on RGB LED, how does it work, schematic diagram, and types. The development of LEDs led to modern sensors and displays where their increased switching rates are helpful in modern-day communication systems. Whereas the modern advancements in LED have emitted high-level output appropriate for lighting in external locations. Initial LEDs were employed as indicator lamps in the place of incandescent bulbs. The color of the emitted light is known by the amount of energy needed for the electrons to traverse through the semiconductor’s bandgap. An LED is considered as the semiconductor light resource which produces light when there is current flow through the device.
