But unlike simple LEDs, these types of LEDs do not turn on only by applying voltage, they also require a microcontroller.

This controller IC, usually WS2812, allows you to access multiple LEDs with a single digital pin by assigning an address to each LED and providing one wire communication. Addressable LEDs are a new generation of LEDs including a controller IC, in addition to RGB LEDs. For example, if you want to control an RGB LED string containing 60 LEDs, in order to control the color of each LED separately, you need 180 digital pins! So you have to forget controlling each LED individually or use LEDs that are addressable. To control each RGB LED, you need three digital pins of a microcontroller (or the development boards like Arduino). RGB LEDs make a variety of colors based on this model. This numeric value is expressed by the Hex code (2550255 = # FF00FF). You 'should' try to use resistors on each of the RGB LEDs that will produce something close to equivalent brightness. For instance, these values are 255 0 255 (maximum red, maximum blue, and minimum green value) for Magenta. Now, your color will still be picked at random, but with an adjustment for intensity. In this model, each color has a value between 0 and 255 for each red, green and blue colors. for example, a red and blue combination produces a magenta color. The RGB LED creates all the colors based on the three colors of red, green, and blue.

Components Required: Arduino Pro Mini (or) Arduino Uno/Nano/Micro Any One. You can include more patterns if you like. The program has totally 6 different patterns and the Arduino chooses the patterns randomly by itself. Using the LEDs in different colors was so attractive that it caused the production of multi–color LEDs or RGB LEDs. In this project, we will make LEDs blink in different patterns in a random manner. In most electronic projects, you can find at least one single LED. After 1962, when the first LED was made and tested, this valuable piece became an inseparable part of our lives.
