Hello Guys in this tutorial we will see how to fade on and off LED with Arduino. for this you will need

  1. Arduino,
  2. Breadboard,
  3. Jumper Wire,
  4. 220 ohms Resistor,
  5. LED.

Do connection as shown in diagram. Then upload the code

int led = 6; // 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

// the setup routine runs once when you press reset:
void setup() {
// declare pin 6 to be an output:
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
// set the brightness of pin 6:
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);
}

Keep learning keep making 🙂
