Nextion触摸屏Arduino Mega 2560关闭和打开继电器

我有点问题 .

我正在尝试使用Nextion触摸屏控制我的越野灯 . 我使用的是Arduino Mega 2560主板 . 一个8模块继电器板 . 和Nextion屏幕 . 我写过的草图一切正常，除非我开火后继电器我无法将其关闭 . 在草图中我也在第一个按钮切换中发布我正在读取引脚的状态然后根据状态将其关闭或打开 . 那现在什么也没做 . 它既不会触发继电器，也不会将其关闭 .

在按钮的其余部分切换时，我只需在按钮切换时触发继电器 .

按钮切换中调用的消息不会根据按钮状态而更改 . 否则我会用它来关闭继电器 .

伙计们我不知所措 . 任何指导将不胜感激 .
