ch3_1閃爍LEDx8

8顆LED接9,8,7,6,5,4,3,2

低電位作動(高電位作動也可)

//ch3_1

const int LED[8]={9,8,7,6,5,4,3,2};

int onoff=1;

void setup()

{

  for(int i=0;i<8;i++)

  {

    pinMode(LED[i],OUTPUT);

    digitalWrite(LED[i],1);

  }

}

void loop()

{

  for(int i=0;i<8;i++)

  {

    digitalWrite(LED[i],onoff);

    onoff=!onoff;

  }

  delay(250);

  onoff=!onoff;

}
