Interfacing KY-016 RGB Full Color LED Module with Arduino

Introduction

In this tutorial, we are Interfacing KY-016 RGB Full Color LED Module with Arduino, The KY-016 Full Color RGB LED module emits a wide range of various colors by combining red, green, and blue light. Each color is adjusted by using Pulse Width Modulation (PWM). Overall, the KY-016 RGB Full Color LED Module provides a versatile and cost-effective solution for a wide range of lighting and decoration applications.

This module is compatible to interface with popular electronic platforms like Arduino, ESP32, Raspberry Pi, and other microcontrollers.

Hardware Required

You will require the following Hardware Components for the Interfacing KY-016 RGB Full Color LED Module with Arduino.

What is a KY-016 RGB Full Color LED Module?

KY-016 RGB Full Color LED Module is an electronic module that consists of a full-color LED light emitting diode (RGB LED). It can produce various colors by mixing red, green, and blue light, making it ideal for creating a wide range of colors and shades.

The module typically has four pins: two for power (VCC and GND), one for the red light, one for the green light, and one for the blue light. The color and brightness of the LED can be controlled by varying the intensity of the individual red, green, and blue light-emitting diodes.

Specifications

This module contains three 150Ω limiting resistors to prevent burnout, a 5mm RGB LED, and 4 male header pins. Changing the PWM signal on each color pin will result in various colors.

The following circuit shows you the connection of the Interfacing KY-016 RGB Full Color LED Module with Arduino, Please make the connection carefully

Circuit Connections

Place the module on the BreadBoard and connect the red pin (R) of the module to pin 11 of the Arduino. connect the Blue (B) of the module to pin 10 of the arduino, connect the green (G) pin of the module to pin 9 of the arduino, and finally ground (-) of the module to the GND of the arduino respectively.

Installing Arduino IDE Software

First, you will require to Download the updated version of Arduino IDE Software and Install it on your PC or laptop. if you Learn How to install the Arduino step-by-step guide then click on how to install Arduino Button given Blow

Code

The following Arduino code will slowly increase/decrease the PWM values on the red, green, and blue pins resulting in the LED cycling through different colors.

int redpin = 11; // select the pin for the red LED
int bluepin =10; // select the pin for the  blue LED
int greenpin =9; // select the pin for the green LED
int val;
void setup() {
  pinMode(redpin, OUTPUT);
  pinMode(bluepin, OUTPUT);
  pinMode(greenpin, OUTPUT);
  Serial.begin(9600);
}
void loop() {
  for(val = 255; val > 0; val--)
  {
    analogWrite(11, val);
    analogWrite(10, 255 - val);
    analogWrite(9, 128 - val);
    Serial.println(val, DEC);
    delay(5); 
  }
  for(val = 0; val < 255; val++)
  {
    analogWrite(11, val);
    analogWrite(10, 255 - val);
    analogWrite(9, 128 - val);
    
    Serial.println(val, DEC);
    delay(5); 
  }
}
