KY-009

This is the KY-009 RGB Full color LED SMD Module.

This module has a 5050 surface mount RGB LED that can be used to create virtually any colour by varying the intensity of the 3 colours by using the PWM output. Resistors will be needed to connect to an Arduino.

Voltage :
Red 1.8 to 2.4VDC
Green 2.8 to 3.6VDC
Blue 2.8 to 3.6VDC

int redpin = 11; 
int bluepin =10;
int greenpin =9;
 
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(redpin, val);
   analogWrite(bluepin, 255-val);
   analogWrite(greenpin, 128-val);
   delay(1); 
  }
 
  for(val=0; val<255; val++)
  {
   analogWrite(redpin, val);
   analogWrite(bluepin, 255-val);
   analogWrite(greenpin, 128-val);
   delay(1); 
  }

  digitalWrite (greenpin, LOW);  // LED will be switched off
  digitalWrite (bluepin, LOW);   // LED will be switched off
  delay (3000); // Wait for 3 seconds
  
  digitalWrite (redpin, LOW);    // LED will be switched off
  digitalWrite (greenpin, HIGH); // LED will be switched on
  digitalWrite (bluepin, LOW);   // LED will be switched off
