我试图让 arduino 中的 millis 工作不知道如何

Question

嗨，我正在尝试使用 millis 在我的 arduino 代码中重新启动功能，但我可以让它工作。

这就是我希望它在 3 秒后关闭 switch3 并重新启动它的方式。

  if (readString.indexOf("?b24vb2ZmL2Z1bmN0aW9u") >= 0)
  {
    //What it does.
    actionTransmitter.sendSignal(1, 'C', false);
    switchstatus3 = false;
    delay(3000);
    actionTransmitter.sendSignal(1, 'C', true);
    switchstatus3 = true;
  }

这就是我做事和失败的方式。

  if (readString.indexOf("?b24vb2ZmL2Z1bmN0aW9u") >= 0)
  {
    //What it does.
    actionTransmitter.sendSignal(1, 'C', false);
    switchstatus3 = false;
    timing = true;
    startTime = millis();
    if ((timing) && millis() - startTime >= 3000) {
      actionTransmitter.sendSignal(1, 'C', true);
      switchstatus3 = true;
    }
  }

这是所有的arduino代码。

Answer 1

我不明白使用第一种方法有什么问题。如果你想要 3s，那么只需延迟 3000 就可以了。但是既然你想要第二种形式，你的代码应该是这样的：

if (readString.indexOf("?b24vb2ZmL2Z1bmN0aW9u") >= 0)
  {
    //What it does.
    actionTransmitter.sendSignal(1, 'C', false);
    switchstatus3 = false;
    timing = true;
    startTime = millis();
    if(timing){

        while(millis() - startTime < 3000); // This will wait 3s

        actionTransmitter.sendSignal(1, 'C', true);
        switchstatus3 = true;
    }
  }
