在按下按鈕時運行一個循環

我需要幫助爲線路跟蹤器循環一些語句，只要按下鍵盤上的'0'並且要繼續循環直到再次按下按鈕，然後再返回到運行主循環。任何幫助是最受歡迎的。在按下按鈕時運行一個循環

如果你想有一個按鈕被按下後，你的代碼繼續做需要的東西，一旦按下按鈕被設置並再次按下該按鈕復位「切換」變量。

在您的全局聲明，你可以把bool mustDoIt = false;並在main()：

if (keyPressed) { 
    mustDoIt = !mustDoIt; 
} 

if (mustDoIt) { 
    ... 
}

不少東西，我注意到：

  • 您有temp大if ... else（其中的方式不是一個好名字，它可能是temperature或temporary），您可以在其中調用另一個函數，在其中您可以進行相同的檢查。爲什麼不將溫度傳遞給函數並在函數中檢查它？
  • 你重複代碼幾次，

考慮編寫一個函數是：

喜歡的東西：

void displayMessage(char *first_row, char *second_row) { 
    lcd.setCursor(0, 0); 
    lcd.print(first_row); 
    lcd.setCursor(0, 1); 
    lcd.print(second_row); 
    digitalWrite(led, HIGH); 
    delay(200); 
    beep(150); 
    digitalWrite(led, LOW); 
    delay(200); 
}
  • 你基本上只檢查temp，state和lightReading，正如我所說，移動支票，你真正需要他們。將這三個變量傳遞給doSomething並在那裏進行檢查。

事情是這樣的：

void doSomething(float temp, int state, int lightReading) { 
    if (temp >= 35 && temp < 50) 
    { 
    displayMessage(" Room Hot!! ", ""); 
    } else if (temp >= 34 && temp < 35) 
    { 
    displayMessage(" Room Warm! ", ""); 
    } else if (temp >= 50) 
    { 
    displayMessage(" Warning  ", " Danger!! "); 
    } //...Add rest of the checks here 

    switch (state) { 
    case 1: //Motor 
     digitalWrite(motor1Pin1, HIGH); 
     digitalWrite(motor1Pin2, LOW); 
     digitalWrite(motor2Pin1, LOW); 
     digitalWrite(motor2Pin2, HIGH); 
    break; 
    case 2: 
     digitalWrite(motor1Pin1, HIGH); 
     digitalWrite(motor1Pin2, LOW); 
     digitalWrite(motor2Pin1, LOW); 
     digitalWrite(motor2Pin2, LOW); 
    break; 
    //...Add rest of the checks here 
    }

而且同樣適用於lightReading。

此外，digitalClockDisplay功能可以寫爲：

void digitalClockDisplay() { 
    char time_string[32]; 
    char date_string[32]; 

    memset(time_string, 0, 32); 
    sprintf(time_string, "Time: %02d:%02d:%02d  ", hour(), minute(), second()); 
    memset(date_string, 0, 32); 
    sprintf(date_string, "date: %02d.%02d.%02d  ", day(), month(), year()); 

    displayMessage(time_string, date_string); 

    Serial.println(time_string); 
}

我現在不能測試的代碼，但我希望這給你的一些想法。

好的。明天一旦我回到學校，我會嘗試編輯代碼。一旦完成，將會更新。非常感謝。 –
