Arduino 代码错误，望改正

问题遇到的现象和发生背景

遇到的现象和发生背景，请写出第一个错误信息

用代码块功能插入代

情况是这莫个情况，Arduino 的以下代码存在错误，可能是参数问题.我是要做一个三路抢答器的，需要满足的要求是当一轮抢答开始后，假如红（1号）抢到了，此时其余两个按键失效，且一位数码管显示数字1，同理2，3。每当一轮结束，裁判会来按下复位键使得数码管上的数字是0且蜂鸣器发出响声希望各位dl帮帮忙，改正改正吧

在给出的代码中，存在多个语法错误和逻辑错误，需要进行以下改正：

1. 在 setup 函数中，digital_0、digital_1、digital_2、digital_3 函数的定义应该放在函数外面，并且不需要在定义函数的语句后面加上分号。此外，应该将 pinMode(A4,INPUT) 改为 pinMode(A4,OUTPUT)，因为 buzzer 是输出设备。
2. 在 loop 函数中，digitalRead 函数的使用方法不正确。digitalRead 函数只需要传递一个参数，即需要读取的引脚号，函数返回值为读取到的电平值。因此应该将 digitalRead(6,1) 改为 digitalRead(6)，digitalRead(7,1) 改为 digitalRead(7)，以此类推。
3. 在 digital_1、digital_2、digital_3 函数中，调用 digitalWrite 函数时应该传递两个参数，即需要设置电平的引脚号和电平值。因此应该将 digital_1; 改为 digital_1()，并在函数内部调用 digitalWrite(6, HIGH)、digitalWrite(7, HIGH)、digitalWrite(2, LOW)、digitalWrite(10, LOW)、digitalWrite(11, LOW)、digitalWrite(9, LOW)、digitalWrite(8, LOW) 等语句。
4. 在 loop 函数中，if 语句中的 !digitalWrite 应该改为 !digitalRead，因为需要判断按键引脚的电平值是否为低电平。同时，digital_1、digital_2、digital_3 函数的调用应该加上括号，即改为 digital_1()、digital_2()、digital_3()。在复位键按下后，应该使用 digitalWrite(A4, LOW) 将 buzzer 停止响。

按我的理解改成以下试试：

if(digitalRead(A2)&& state==1){
    digitalWrite(5,HIGH); 
    state=0;
   digital_1;
   digitalRead(6,1);
   digitalRead(7,1);
  }
   if(digitalRead(A1)&& state==1){
    digitalWrite(4,HIGH); 
    state=0;
   digital_2;
   digitalRead(2,1);
   digitalRead(6,1);
   digitalRead(8,1);
   digitalRead(9,1);
   digitalRead(11,1);
   }
    if(digitalRead(A0)&& state==1){
    digitalWrite(3,HIGH); 
    state=0;
    digital_3;
   digitalRead(2,1);
   digitalRead(6,1);
   digitalRead(7,1);
   digitalRead(8,1);
   digitalRead(11,1);
   
    }
    if (digitalRead(A4)&& state==0)  {

这样一个代码为什么蜂鸣器没有响声，绿色的灯一直亮着且复位键没有起到作用？@MarkHan_
