/*
此文件需安裝Arduino esp8266開發環境支持，環境搭建參見：http://www.embanju.org/talk/237.html
本程序可以用來控制四路繼電器
ESP8266燒入此程序直接，使用高低電頻控制光耦繼電器來控制電燈
我的繼電器默認高電頻關閉，所以在初始化時都初始化為高電頻，play關閉開啟，stop關閉關閉，輸入1-4打開或關閉對應的引腳
代碼基于https://github.com/bigiot/bigiotArduino/blob/master/examples/ESP8266/kaiguan/kaiguan.ino
上的代碼進行調整，修復了部分bug，解決了斷線重連問題，此代碼可以直接燒入到nodemcu模塊，分享代碼希望對大家有幫助
