LED Blink

C/C++
int led = 13;

//          
void setup() {

  pinMode(led, OUTPUT);  //  LED_BULTIN OUTPUT  
}

// 
void loop() {
  digitalWrite(led, HIGH);   // LED   (LED  HIGH)
  delay(1000);                       // 1 
  digitalWrite(led, LOW);    // LED  (LED  LOW)
  delay(1000);                       // 1 
}

LED Fade

C/C++
int led = 13;           // PWM( )  13 led  
int brightness = 0;    //   brightness 
int fadeAmount = 5;    // fade  


void setup() {
  // declare pin 13 to be an output: 13 OUTPUT 
  pinMode(led, OUTPUT);
}

// 
void loop() {
  //  led(13) 
  analogWrite(led, brightness);

  // brightness fadeAmount   
  brightness = brightness + fadeAmount;

  // brightness  0  255   fadeAmount  - 
  if (brightness <= 0 || brightness >= 255) {
    fadeAmount = -fadeAmount;
  }
  //  30 milli    
  delay(30);
}
