KY-016 RGB 3 Color LED Module for Arduino DIY 3.3 / 5V Three Color 4pin

KY-016 ARDUINO CODE

The following Arduino sketch will gradually increase/decrease the PWM values on the red, green and blue pins causing the LED to cycle through various 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(11, val);
analogWrite(10, 255 - val);
analogWrite(9, 128 - val);
Serial.println(val, DEC);
delay(5);
}
for(val = 0; val < 255; val++)
{
analogWrite(11, val);
analogWrite(10, 255 - val);
analogWrite(9, 128 - val);

Serial.println(val, DEC);
delay(5);
}
}
