Blink Blink

 Hi, this is my Blink: 

This is my code:

// Blink: Turns LED on for a second, then off for a second
//pin 13 name
int led = 13;
//setup routine runs once when reset is pressed
void setup() {
  //initialize the digital pin as an output
  pinMode(led, OUTPUT) ;
}

//the loop routine runs over and over again :
void loop() {
digitalWrite(led,HIGH);   //turn LED on
delay(500) ;            //waits a second
digitalWrite(led,LOW);   //turn the LED off
delay(500);            //waits a second
}
