Single LED Circuit Diagram

LED Blinking Code

int led = 13;

void setup() {
pinMode(led, OUTPUT);
}

void loop() {
digitalWrite(led, HIGH);
delay(1000);
digitalWrite(led,LOW);
delay(1000);
}

LED Fading Code

int brightness_led = 0;
int led = 13;

void setup()
{
  pinMode(led, OUTPUT);
}
void loop()
{

  for (brightness_led = 0; brightness_led <= 255; brightness_led += 5) {
    analogWrite(led, brightness_led);
    delay(50); // Wait for 50 millisecond(s)
  }

  for (brightness_led = 255; brightness_led >= 0; brightness_led -= 5) {
    analogWrite(led, brightness_led);
    delay(50); // Wait for 50 millisecond(s)
  }
}
