/*
Blink
Turns on an LED for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13; // set the variable “led” to the value 13
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, HIGH); // turn the LED on
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off
delay(1000); // wait for a second
}예제 - 13번 핀을 출력으로 사용
pinMode(13, OUTPUT)예제 - 13번 핀을 HIGH 상태로 만들어라
digitalWrite(13, HIGH)예제 - 1초 동안 지연
delay(1000);
