我将如何优化此代码，以便我的arduino nodemcu一段时间后不会崩溃

Question

我有这个物联网项目，它控制着变色龙的饲养容器。它具有一个连接到D5和D6引脚的继电器以控制灯光。我的Nodemcu 0.9在约20个小时后停止工作（此时灯熄灭并且无法重新打开，我总是必须重置Nodemcu）。

我一直在阅读堆栈，发现字符串使用了大量的堆内存，因此我删除了所有字符串，但是问题仍然存在。

main.cpp

AppRegistry.registerComponent('AFApplication', () => <DevMenuTrigger>{SimpleApp}</DevMenuTrigger>);

您能帮我解决这个问题吗？我不是程序员，而是业余爱好者，所以我真的很难弄清楚这一点。
