[Arduino] Make Full color LED Lamps bright

Document :

Spec

This Full color LED Lamps is common anode.



The pin number 1 of Full color LED Lamp connect to Digital pin ~3.( ~3 mean can do fade function)

The pin number 2 of Full color LED Lamp connect to Digital pin ~5.

The pin number 4 of Full color LED Lamp connect to Digital pin ~6.

/*

 Fade

 

 This example shows how to fade an LED on pin 9

 using the analogWrite() function.

 

 This example code is in the public domain.

 */



int led3 =3;           // the pin that the LED is attached to

int led6 = 6;           // the pin that the LED is attached to

int led9 = 9;           // the pin that the LED is attached to

int brightness = 1;    // how bright the LED is

int fadeAmount = 1;    // how many points to fade the LED by



// the setup routine runs once when you press reset:

void setup()  {

  // declare pin 9 to be an output:

  pinMode(led3, OUTPUT);

  pinMode(led6, OUTPUT);  

  pinMode(led9, OUTPUT);    

}



// the loop routine runs over and over again forever:

void loop()  {

  // set the brightness of pin 9:

  analogWrite(led3, brightness );    

  analogWrite(led6, brightness % 10);

  analogWrite(led9, brightness % 20);  

 

  // change the brightness for next time through the loop:

  brightness = brightness + fadeAmount;



  // reverse the direction of the fading at the ends of the fade:

  if (brightness == 0 || brightness == 10) {

    fadeAmount = -fadeAmount ;

  }     

  // wait for 30 milliseconds to see the dimming effect    

  delay(30);
