此为本人在本学期单片机创新课程中做的实验之一。本实验基于nec单片机，Applilet2 for 78K0KX2和SM+编译器实现的按键-亮灯实验。虽然程序本身并不复杂，但是由于nec的源码相对稀有，相信该程序是对特定人群，尤其是和我一样也要上单片机创新课程的同学是很有帮助的。-This do for himself in this microcontroller innovation course of one of the experiment.This experiment based o

硬件采用STM32 C8作为主控、两个红外传感器、蜂鸣器、LED灯，家居红外报警系统可以应用在实际场所。(The hardware uses STM32 C8 as the main control, two infrared sensors, buzzers, LED lights, home infrared alarm system can be used in actual places.)
