"error: break statement not within loop or switch" in arduino one

Question

我对编码一窍不通，但我正在做一个学校练习，它给了我标题的错误

while (distancia<200 && distancia>100);
{

  lcd.print("ALTO");
  delay(1000);
  lcd.clear();
  delay(1000);

  if(distancia<100)
  {

   break;
  }
}
 if(distancia<100);
  {

    lcd.print("INTRUSO EN");
    lcd.setCursor(0,1);
    lcd.print("LA PUERTA");
    tone(11,700,250);
    digitalWrite(8,HIGH);
    delay(500);
    lcd.clear();
    digitalWrite(8,LOW);
    delay(500);
}
}

它在arduino中，我希望它returns到第一个，如果（100

Answer 1

这里

  while (distancia<200 && distancia>100);
  --------------------------------------^

删除那个分号，它终止 while 就在那里

    while (distancia<200 && distancia>100)
