有请各路大神来相助，萌新一枚，我做的跑马灯最后一个怎么不听话*

因为你5从开始就是high，直到最后才有个low，所以出问题了

5->high之后要加个5->low

亮的逻辑不对，应该改为下面的：
void loop()
{
digitalWrite(6,HIGH);
delay(300);
digitalWrite(6,LOW);
delay(300);
digitalWrite(7,HIGH);
delay(300);
digitalWrite(7,LOW);
delay(300);
digitalWrite(8,HIGH);
delay(300);
digitalWrite(8,LOW);
delay(300);
digitalWrite(9,HIGH);
delay(300);
digitalWrite(9,LOW);
delay(300);
digitalWrite(10,HIGH);
delay(300);
digitalWrite(10,LOW);
delay(300);
digitalWrite(11,HIGH);
delay(300);
digitalWrite(11,LOW);
delay(300);
}

因为它跑马了
