2D16 KY-016 RGB 3 Color Full Color LED Module

Description

RGB LED module consists of a plug-in full color LED made by R, G, B three pin PWM voltage 
input can be adjusted section three primary colors (red/blue/green) strength in order to achieve full color mixing effect. Control of the module with the Arduino can be achieved cool lighting effects.

Specifications

This module consists of a 5mm RGB LED, 3 150Ω limiting resistors to prevent burnout and 4 male header pins. Adjusting the PWM signal on each color pin will result on different colors.

Features

1. the use of plug-in full-color LED 
2. RGB trichromatic limiting resistor to prevent burnout 
3. through the PWM adjusting three primary colors can be mixed to obtain different colors 
4. with a variety of single-chip interface 
5. the working voltage: 5V 
6. LED drive mode: common cathode driver

Connection Diagram

Connect the module red pin (R) to pin 11 on the Arduino. Blue (B) to pin 10, green (G) to pin 9 and ground (-) to GND.

Code

The following Arduino sketch will gradually increase/decrease the PWM values on the red, green and blue pins causing the LED to cycle through various 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); 
  }
}
