Arduino求助！关于led交替闪烁的问题！

xiejinxue

我在程序里面是让led延时1秒交替闪烁，为什么在仿真里面过了好久才亮？
const int buttonPin = 8;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);      
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);     
}

void loop(){
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == LOW) {     
    // turn LED on:   
    digitalWrite(ledPin, HIGH);
    delay(1000);
    digitalWrite(ledPin,LOW);
   delay(1000);
  }
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

const int buttonPin = 8;     //设置 8 为输入按钮

你图上怎么没有？！

你这段程序的功能是：按下  buttonPin 后 ledPin 就亮1秒灭1秒，否则 ledPin 熄灭。

要去掉const
