如果我输入 LCD 循环代码，Arduino 会停止我的代码

Question

我对 Arduino 有点陌生，英语不是我的第一个语言，所以可能会出现一些错误。

我只是将做一个项目作为一种爱好来保持时间。我正在尝试获取空气温度、水温和水流量。对于我正在使用的这些数据

LM35DZ、DS18B20、YF-S201

尽管我从其他项目中获得了一些代码，但它们运行良好。我正在从串行监视器获取这些数据，并且我有一个 LCD 来查看这些数据。

在我输入 LCD 代码后，void setup 部分工作得很好。我得到了 A: H: S: / 它们应该在的位置（当您查看设置中我的代码的 LCD 部分时，您会明白我在说什么）。对于循环部分，当我将 lcd 代码放在末尾时它不起作用，并且在串行监视器上它在计算水流时停止（如果我删除这些代码，串行监视器工作得很好）。

我把我的整个代码放在你需要看的地方。你可以直接跳到问题。

}

Answer 1

尝试在以下内容之前添加lcd.clear()；

  lcd.setCursor(3,0);
  lcd.print(Calc);
  lcd.setCursor(10,0);
  lcd.print(sicaklik);
  lcd.setCursor(3,1);
  lcd.print(susicakligi);
  lcd.setCursor(11,1);
  lcd.print(ptsck);

之后是delay(100);。
