The KY-016 3-color LED module.
The KY-016 RGB LED module consists of a tri color LED, you can adjust the intensity of the three primary colors (red / blue / green) by altering the PWM voltage inputs of the R, G and B pins to achieve full color mixing.

Code
//KY016 3-color LED module
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);
}

for (val = 255; val> 0; val --)
{
analogWrite (11, val);
