product description

Schema

Since you can't connect the led's directly to the Arduino you will need resistors!!

  • Arduino pin 9 --> 180 Ohm resistor --> Pin 'R' of KY-009 module
  • Arduino pin 10 --> 100 Ohm resistor --> Pin 'G' of KY-009 module
  • Arduino pin 11 --> 100 Ohm resistor --> Pin 'B' of KY-009 module
  • Arduino GND --> pin '-' of KY-009 module

Example Code

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=0;
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);
  }
  Serial.println (val, DEC);
}
