Schematic

• Arduino pin 10 --> resistor 330 Ohm --> Signal pin of the module
• Arduino pin 11 --> resistor 330 Ohm --> Middel pin of the module
• Arduino GND --> module -/GND

Example Code

// Arduino test code for KY011
int redpin = 11; // select the pin for the red LED
int greenpin = 10; // select the pin for the green LED
int val;
void setup () {
   pinMode (redpin, OUTPUT);
   pinMode (greenpin, OUTPUT);
}
void loop () {
   for (val = 255; val> 0; val--)
      {
      analogWrite (greenpin, val);
      analogWrite (redpin, 255-val);
      delay (15);
   }
   for (val = 0; val <255; val++)
      {
      analogWrite (greenpin, val);
      analogWrite (redpin, 255-val);
      delay (15);
   }  
}
