基于Arduino开发，借助blinker物联网平台，让NodeMCU实现8路继电器APP端状态监视和控制
先上开发板功能图：
本文利用了NodeMCU上的D0-D3,D5-D9,总共 8个 GPIO口，一个板载LED状态控制和显示。
主要的功能是通过NodeMCU开发板，在手机APP端实现远程查看，操控，定时控制。
手机端：
打开APP：
进入新建好的NodeMCU
按键属性参数
编辑功能按钮属性状态
指定一个功能按钮设置项
显示图标有非常丰富的素材图标供选择，这里就不一一展示了，根据个人喜好选择。
最关键的参数是
数据键名一定要与源代码定义的一致。按键类型选择：开关按键
设置好后，记得点右上角的保存。
定时功能：
定时设置详细界面
具体设置时间
设置完成如下：
