// 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);
  pinMode(12, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(9, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  //for(int i=9;i<=13;i++){
  digitalWrite(random(9,14), HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(10);
  digitalWrite(random(9,14), LOW);    // turn the LED off by making the voltage LOW
  delay(10);
  //}
  //digitalWrite(12, HIGH);   // turn the LED on (HIGH is the voltage level)
  //digitalWrite(12, LOW);    // turn the LED off by making the voltage LOW
  //delay(1000);  //延遲時間
  //digitalWrite(11, HIGH);   // turn the LED on (HIGH is the voltage level)
  //digitalWrite(11, LOW);    // turn the LED off by making the voltage LOW
  //delay(1000);
  //digitalWrite(10, HIGH);   // turn the LED on (HIGH is the voltage level)
  //digitalWrite(10, LOW);    // turn the LED off by making the voltage LOW
  //delay(1000);
  //digitalWrite(9, HIGH);   // turn the LED on (HIGH is the voltage level)
  //digitalWrite(9, LOW);    // turn the LED off by making the voltage LOW

}

pinMode(13,OUTPUT);  =>設13接孔為輸出
digitalWrite(13,HIGH)  =>亮  LOW就是暗
delay是指延遲，1000=1秒
