Question

我一直在忙着编写一个arduino代码，该代码使用基于PIR传感器的IR打开和关闭屏幕。在我添加额外的代码以阻止设备每次从PIR传感器获得输入时都停止发送IR信号之前，该设备一直在工作。我是以“ counterSensor”的形式完成的，您可以在下面的代码中找到。

自从我添加计数器以来，我的设备不再发送IR信号。我尝试查找任何硬件故障（我更换了IR指示灯，并使用普通的蓝色指示灯对其进行了测试。两次均无效）。我还尝试使用IR库中的示例代码，该代码应该可以正常工作，但是我什么也没得到。

我也在另一种arduino上尝试了所有这些方法，但是对该arduino也没有任何作用。

有人可以帮我吗？

提前谢谢！

由于添加了故障安全功能，代码无法正常运行
