arduino简易流水灯（新手之路）

先定义8到13六个引脚，负极依次连在每一个引脚上，正极连在power中5v的引脚上

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);
