和我的阿迪诺有麻烦

Question

抱歉，标题含糊不清，但我不知道该怎么写，因为我真的不知道我的问题是什么。为连接到arduino的运动传感器编写了一些代码。每次运行脚本时，它都绕过while循环，因为某种原因我标记了这个循环，然后执行下面的代码并停止。

int buzzPin = 8;
int upPin = 7;
int downPin = 6;
int motionPin = 12;
int redLed = 4;
int amberLed = 3;
int greenLed = 2;

void setup() {
  pinMode(buzzPin, OUTPUT);
  pinMode(redLed, OUTPUT);
  pinMode(amberLed, OUTPUT);
  pinMode(greenLed, OUTPUT);
  pinMode(upPin, INPUT);
  pinMode(downPin, INPUT);
  pinMode(motionPin, INPUT);
}

void loop() {
  delay(1000);
  digitalWrite(greenLed, HIGH);
  digitalWrite(amberLed, LOW);
  while(!digitalRead(upPin)==HIGH); //this is just bypassed when 'upPin' is not high
  if(digitalRead(upPin)==HIGH){
    digitalWrite(greenLed, LOW);
    digitalWrite(amberLed, HIGH);
    digitalWrite(buzzPin, HIGH);  //delay before arming the motion sensor
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(250);
      digitalWrite(buzzPin, LOW);
      delay(250);
      digitalWrite(buzzPin, HIGH);
      delay(1000);
      digitalWrite(buzzPin, LOW);
    } //stops here...
    while(!digitalRead(motionPin)==HIGH);
    disarm();
    alarm();
}

bool disarm(){ //button combination to disarm the motion sensor and stop the alarm
  int i = 0;
  while(true){
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(upPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(upPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(downPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(upPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(downPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    while(digitalRead(upPin)||digitalRead(downPin));
    while(!digitalRead(upPin)||!digitalRead(downPin)){i++; 
    delay(1000);
    if(i == 5){
      return(false);
      }
    }
    if(digitalRead(downPin)==HIGH){
      int i = 0;
      }
    else{continue;}
    break;
    }
  return(true);
  delay(50);
  return(false);
  }

  void alarm(){
    digitalWrite(redLed, HIGH);
    digitalWrite(amberLed, LOW);
    while(disarm()==false){
      digitalWrite(buzzPin, HIGH);
      delay(500);
      digitalWrite(buzzPin, LOW);
      delay(500);
      }
    }

如果有人能告诉我我的问题是什么以及如何解决它，那就太好了。

Answer 1

循环()

(这不是一个循环，而是一个持续了很长时间的不间断延迟的集合)

这是：

 void loop() {
    show_green();
    hang_until(upPin, LOW); // this can last forever
    show_amber();
    buzz_a_while(); // blocks a couple of seconds
    hang_until(motionPin, LOW); // this seems to last forever
    disarm();
    alarm();
    delay(1 sec);
}

因此，只要强迫upPin和motionPin永远保持低位，您就不会注意到“停止”。

但是()在arduino编码中总是可疑的，因为它禁用了arduino的主要特性:永远运行循环函数。

Answer 2

您在第一个while循环的注释中写道，如果引脚不高，就会绕过它。但是，您有一个否定运算符(!)就在看上去很奇怪的情况之前。我建议你把它去掉。之后的语句似乎也没有必要，因为它只是在checka的条件下进入循环。
