About This Project

In this tutorial, you will learn about How to make RGB LED Color Mixing With Arduino. The RGB led consists of three different LEDs, from the name you can guess that these leds are red, green and blue. We can obtain many other colours by mixing up these colours. The Arduino has an analog write function which will help us in obtaining different colours for Arduino RGB LED.

Introduction

LED (light-emitting diode) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.

Red, green, and blue (RGB) LED is the most commonly used component for various electronic projects like portable flashlights, LED indicators, and more. RGB is referred to as the primary colors of light. Mixing the colors helps in generating new colors. RGB is for sensing, representing, and displaying images in an electronic system.

Applications of RGB LED

RGB LED is used in various industrial applications, light guides, decorative lights, LCD backlights, multicolor lights, portable flashlight/torchlight, indoor, and outdoor settings, automotive industry. etc.
