First, define the pins: 11 for blue, 12 for green, and 13 for red.RGB LED modules are typically in male headers. and converting it to a RGB range (0 - 255). Once thatâs done, connect your Arduino to your PC and upload this sketch below. If you have an unofficial Arduino-based microcontroller board, make sure that itâs using female pin headers. Youâre going to need 3 in this case for each color (red, green and blue). Examples are the Uno, Duemilanove, Mega, and Leonardo. include define LEDCOUNT 60 define LEDOUT 13 define BUTTONIN 10 define ANALOGINPUT A9 define EXTRAPINA 7 define EXTRAPINB 11 struct CRGB leds LEDCOUNT int waittime 5 void.I was wondering how to get more than 0-255 if not all the colors. By controlling the intensity of each of these colors, you can produce a wide range of colors, including white when all three are at full intensity. Here is my code below, which cycles through the initial rainbow of 0-255. This method only works on Arduino boards with a GND pin next to pin 13. How does the RGB LED work in Arduino An RGB LED (Red, Green, Blue Light Emitting Diode) is a specialized type of LED that can emit light in three primary colors: red, green, and blue. How to Use an RGB LED Module Using the Digital Method
