完成的任务

本文章主要完成I/O控制灯的部分，通过四路继电器组，完成对四个地方灯的控制。

程序分类

名称

功能

主程序

mainPro.c

头文件

inputCommand.h

用于声明指令工厂部分的函数、结构体

contrlDevice.h

用于声明控制工厂部分的函数、结构体

子程序

bathroom.c

浴室灯部分的程序、结构体

livingroom.c

客厅灯部分的程序、结构体

secondfloor.c

二楼灯部分的程序、结构体

Kitchen.c

餐厅灯部分的程序、结构体

注：在实现功能时，需充分发挥工厂模式的优点，我们在创建对象时不会对客户端暴露创建逻辑，并且是通过使用一个共同的接口来指向新创建的对象。
==在代码编写，只需写好一个部分的灯控程序，其他部分直接ctrl+c\ctrl+v即可。==
使用的I/O口：

头文件

inputCommand.h

本部分还未接入语音控制与Socket，故使用的是scanf来手动输入指令，所以此处inputCommand.h未使用，后序章节会使用。
