改普通排插为四路贝壳物联智能排插

因为懒，不想走去打开开关，所以就改普通排插为智能排插，打开排插发现里面的空间足够放四个继电器模块等。上图：

只拍了两张图，其他的懒得拍了

支持天猫精灵

附上代码

/*
此文件需安装Arduino esp8266开发环境支持，环境搭建参见：http://www.bigiot.net/talk/237.html
本程序可以用来控制四路继电器
ESP8266烧入此程序直接，使用高低电频控制光耦继电器来控制电灯
我的继电器默认高电频关闭，所以在初始化时都初始化为高电频，play关闭开启，stop关闭关闭，输入1-4打开或关闭对应的引脚
代码基于https://github.com/bigiot/bigiot ... kaiguan/kaiguan.ino
上的代码进行调整，修复了部分bug，解决了断线重连问题，此代码可以直接烧入到nodemcu模块，分享代码希望对大家有帮助
