我想用 Web 上的按钮和物理按钮使用 NodeMCU 控制相同的 LED

如何解决我想用 Web 上的按钮和物理按钮使用 NodeMCU 控制相同的 LED

我想通过网络上的按钮和物理按钮来控制同一个 LED。我使用 NodeMCU。我尝试运行它们中的每一个并且运行良好。我的网站是用 PHP & Mysql 和 HTML 制作的。当我按下网络上的按钮时，LED 将打开或关闭。然后 NodeMCU 会将 GPIO 状态反馈给数据库并显示在 Web 上。然后，当我按下按钮时，LED 将打开或关闭，然后 NodeMCU 会将 GPIO 状态反馈给数据库并显示在网络上。当我运行它们时，它运行良好。但是当我将它们组合在一起时，它不起作用。这是我的代码。有人可以帮我吗？
