KY-009 RGB Full color LED SMD Module

KY-009 Description

RGB full color LED Module KY-009 for Arduino, emits a range of colors by mixing red, green and blue. The amount of each primary color is adjusted using PWM.

KY-009 Specifications

The KY-009 RGB Full Color LED SMD Module consists of a 5050 SMD LED, use with limiting resistors to prevent burnout. Compatible with popular electronics platforms like Arduino, Raspberry Pi and ESP8266.

KY-009 Example Code

The following Arduino sketch will cycle through various colors by changing the PWM value on each of the three primary 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);

void loop() 
  for(val = 255; val > 0; val--)
    analogWrite(redpin, val);  //set PWM value for red
    analogWrite(bluepin, 255 - val); //set PWM value for blue
    analogWrite(greenpin, 128 - val); //set PWM value for green
    Serial.println(val); //print current value 
  for(val = 0; val < 255; val++)
    analogWrite(redpin, val);
    analogWrite(bluepin, 255 - val);
    analogWrite(greenpin, 128 - val);

I apologize, but better control I saw on sale there are models with the right RGB series at this point necessary to determine which module is using.
Do not consider my previous message!


HI great job, but I wanted indicate that the pins are not in the right order and not -RGB but -GRB. You can correct the component?
