<pre><code>void setup() {
 // D7(13)을 출력으로 설정합니다.
 pinMode(13, OUTPUT); 
}
 
void loop() {
 // D7(13)을 LOW로 설정하여 LED가 꺼지도록 합니다. 
 digitalWrite(13, LOW); 

 // 1초 대기하여 LED 현재 상태를 1초동안 유지하도록 합니다. 
 delay(1000); 
 

 // D7(13)을 HIGH로 설정하여 LED가 켜지도록 합니다. 
 digitalWrite(13, HIGH); 

 // 1초 대기하여 LED 현재 상태를 1초동안 유지하도록 합니다.
 delay(1000); 
}

</code></pre>
