无线控制机械转盘车

操作说明
装配机械控制与主控板散件，完成后将主控板COM与P4短接此时D2指示灯亮起其次进行手动控制测试确保机械装配正常无误。
MCU主控ESP8266连接电脑通过Arduino编译下载测试示例程序，选择下载时需要注意开发板的选择和下载端口如图1_1，编译通过点下载，然后长按ESP8266 Flash按键再点下RST进入下载模式，等待下载进度条开始时松手完事，此时WIFI模块自动复位开始运行下载的程序下载，表面现象为长亮指示灯，待连路由器成功后指示灯为呼吸状态
此时手机下载控制软件，安装成功后将手机连接到与WIFI模块连接的同一网络下，也就是两者处于局域网络下，打开安卓示例APP，进入设置处开始设置连接IP地址与端口号，连接。
开始操作控制
参考示例程序
