[Arduino]用邏輯玩科技

const byte LED1 = 8;
const byte LED2 = 9;
const byte LED3 = 10;

void setup() {
  // put your setup code here, to run once:
  pinMode(LED1,OUTPUT);
  pinMode(LED2,OUTPUT);
  pinMode(LED3,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(LED1, HIGH);
  digitalWrite(LED2, LOW);
  digitalWrite(LED3, LOW);
  delay(100);

  digitalWrite(LED1, LOW);
  digitalWrite(LED2, HIGH);
  digitalWrite(LED3, LOW);
  delay(100);

  digitalWrite(LED1, LOW);
  digitalWrite(LED2, LOW);
  digitalWrite(LED3, HIGH);
  delay(100);
