Fade in and fade out

 Materials required-:

1. Led
2. Arduino
3. 1k Resistor
4. Jumpers
5. Breadboard
   
   
   

This is a simple circuit in which you can control the brightness of led with the help of code . you can also use a resistor less than 1k or may be for more good results don't use a resistor . I Hope you all will enjoy this .If you want me to make a post on your idea or project just let me know in the comment section. 

           HAPPY LEARNING!

                                       ARDUINO CODE

 

    

int led = 9;           // the PWM pin the LED is attached to

int brightness = 0;    // how bright the LED is

int fadeAmount = 5;    // how many points to fade the LED by

void setup() {

  // declare pin 9 to be an output:

  pinMode(led, OUTPUT);

}

void loop() {

  // set the brightness of pin 9:

  analogWrite(led, brightness);

  // 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 >= 255) {

    fadeAmount = -fadeAmount;

  }

  // wait for 30 milliseconds to see the dimming effect

  delay(30);

}
