[따라하기] 아두이노 기초 – LED와 버튼 제어하기 by ODIY 한국과학창의재단

Arduino – LED Wave

#define DELAY_TIME 100


void setup() {
  // put your setup code here, to run once:
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT); 
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(6, LOW);
  digitalWrite(2, HIGH);
  delay(DELAY_TIME);
  digitalWrite(2, LOW);
  digitalWrite(3, HIGH);
  delay(DELAY_TIME);
  digitalWrite(3, LOW);
  digitalWrite(4, HIGH);
  delay(DELAY_TIME);
  digitalWrite(4, LOW);
  digitalWrite(5, HIGH);
  delay(DELAY_TIME);
  digitalWrite(5, LOW);
  digitalWrite(6, HIGH);
  delay(DELAY_TIME);
}

Arduino – LED with button

#define LED 12
#define BUTTON 7

void setup() {
  // put your setup code here, to run once:
  pinMode(LED, OUTPUT);
  pinMode(BUTTON, INPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  if(digitalRead(BUTTON) == HIGH){
    digitalWrite(LED, HIGH);
    delay(1000);
    digitalWrite(LED, LOW);
    delay(1000);
  }
}
