前言

纯小白艰难自学，还好有元宝，你值得拥有，
打开GD32EmbeddedBuilder，导入官方提供的演示案例，softap_tcp_ server，
然后我根据我爱小易大佬的代码在元宝里滚了我需要的代码，大概功能是远程控制浇水系统启动关闭，后续还想添加湿度传感器，太阳能供电充电，水位检测，显示器等等，有试过，可惜毛病很多，浪费了半个多月时间，还是不行，只能先实现远程控制，配合内网穿透，就能实现外网访问控制网站了
基于您的代码框架，我将修改为完整的智能浇水系统，添加远程定时浇水、湿度检测、手动控制等功能。以下是完整的修改后代码：

主要新增功能：​​土壤湿度检测​​ - 实时读取并显示湿度值​​水位检测​​ - 监测水位状态，低水位时自动停止浇水​​三种工作模式​​：🤖 自动模式：根据湿度自动控制⏰ 定时模式：设置定时浇水👆 手动模式：远程手动控制​​实时状态显示​​ - 湿度进度条、水位警告、倒计时等​​响应式界面​​ - 美观的现代化UI设计使用说明：​​编译烧录​​后，设备会创建WiFi热点 SmartWatering_AP​​手机连接​​该热点，密码 12345678​​浏览器访问​​ http://192.168.237.1​​实时监控​​土壤湿度和系统状态​​远程控制​​浇水模式和定时设置硬件连接建议：水泵继电器 → PB2土壤湿度传感器 → ADC0通道0 (PA0)水位传感器 → PA1状态LED → PB0这个系统具备了您需要的所有功能，界面美观易用，适合实际部署使用！
可惜这不知道哪里有问题，元宝也解决不了。
在画个板子整合的好看点，可惜俺是新人得一点点学，ai给的代码总是有问题，第一次测试的时候是能用的，我后面重新烧录之后就出现通电就掉wifi，继电器持续运行等问题，只能以后有空再解决，简单的功能是勉强实现了
以下是我最后能用的简化版，还有一些调整其他文件，可能这就是造成我第二次无法使用的原因。

总结，这个板子是一款很适合新人尝试的开发板，可惜成熟的项目还是太少，相对主流板子，希望以后优秀的项目能越来越多
