KY-009 SPECIFICATIONS

This module consists of a 5050 SMD LED and 4 male header pins. Use with limiting resistors to prevent LED burnout.

Operating Voltage	5V max Red 1.8V ~2.4V Green 2.8V ~ 3.6V Blue 2.8V ~ 3.6V
Forward Current	20mA ~ 30mA
Operating Temperature	-25°C to 85°C [-13°F ~ 185°F]
Board Diemsions	18.5mm x 15mm [0.728in x 0.591in]

CONNECTION DIAGRAM

Connect the red pin (R) to Pin 9, the green pin (G) to pin 10, the blue pin (B) to pin 11 and finally the ground pin (-) to GND.

You must use resistors between the board and the Arduino to prevent LED burnout.

KY-009	Breadboard	Arduino
R	180Ω resistor	Pin 9
G	110Ω resistor	Pin 10
B	110Ω resistor	Pin 11
–		GND

KY-009 ARDUINO 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);
 Serial.begin(9600);
}
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 
  delay(1); 
 }
 for(val = 0; val < 255; val++)
 {
  analogWrite(redpin, val);
  analogWrite(bluepin, 255 - val);
  analogWrite(greenpin, 128 - val);
  Serial.println(val);
  delay(1); 
 }
}
