• Blink codes
  
  [code lang=cpp]
  // the setup function runs once when you press reset or power the board
  void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
  }
  // the loop function runs over and over again forever
  void loop() {
  digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
  delay(1000); // wait for a second
  digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
  delay(1000); // wait for a second
  }
  [/code]

Pin 13 회로도에서 살펴보자

Pin 13으로 L LED를 On/Off 한다.!
