/*
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/bigiotArduino/blob/master/examples/ESP8266/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
