arduino簡易流水燈（新手之路）

先定義8到13六個引腳，負極依次連在每一個引腳上，正極連在power中5v的引腳上

void setup() {                

  pinMode(8, OUTPUT);

  pinMode(9, OUTPUT);

  pinMode(10, OUTPUT);

  pinMode(11, OUTPUT);

  pinMode(12, OUTPUT);

  pinMode(13, OUTPUT);

}

void loop() {

  digitalWrite(8, HIGH);  

  delay(100);

  digitalWrite(9, HIGH); 

  delay(100);

  digitalWrite(10,HIGH);

  delay(100);

  digitalWrite(11,HIGH);

  delay(100);

  digitalWrite(12,HIGH);

  delay(100);

  digitalWrite(13,HIGH);

  delay(100);

  digitalWrite(13, LOW);    

  delay(100); 

  digitalWrite(12, LOW);    

  delay(100); 

  digitalWrite(11, LOW);    

  delay(100); 

  digitalWrite(10, LOW);    

  delay(100); 

  digitalWrite(9, LOW);    

  delay(100);   

  digitalWrite(8, LOW);    

  delay(100);

}

輸出每個引腳，通過寫入高低電壓控制燈的亮暗。應該每個LED要與一個330歐的電阻串聯，由于沒串聯電阻導緻LED過亮。
