因此，我必须创建一个安全系统，可以使用红外遥控器或面包板上的按钮来解锁。面包板按钮延迟的部分功能正常，但是，我的问题出在红外遥控器上。当我输入与遥控器相关的代码时，我的代码将停止工作。
这是我的代码：
// C++ code
//
// In this code, when motion is detected, the alarm will go off, a buzzer will start to beep, and the LED will blink. Now, the user has two options. 1. they can unlock the system using push buttons on the breadboard. Pressing the correct passcode will unlock the system, and the LED and the buzzer will stop. The user can achieve the same functionality using an IR remote. The system will unlock by pressing the correct passcode combinations on the IR.

当我输入红外遥控器的代码时，不仅红外遥控器不起作用，而且 LED、蜂鸣器或 LCD 也不起作用。
