无线控制机械转盘车

操作说明

1. 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。
2. 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
3. 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。
4. 开始操作控制
5. 参考示例程序

#include <ESP8266WiFi.h>
#define MAX_SRV_CLIENTS 4   //最大同时联接数，即你想要接入的设备数量，8266tcpserver只能接入五个

const char *ssid = "iCloud_TP"; ////这里是我的wifi，你使用时修改为你要连接的wifi ssid
const char *password = "icloud_TP"; //你要连接的wifi密码

IPAddress local_IP(192, 168, 1, 133);//加入路由器时192, 168, 0, 1开始或根据路由分配的起始IP可到路由器中查看
IPAddress gateway(192, 168, 0, 1);//加入路由器时192, 168, 0, 1/手机自建服务器时路由网关192, 168, 43, 1
IPAddress subnet(255, 255, 255, 0);
