98行代码，只计算了circuitPython的服务端代码，web控制使用Vue + tailwin css开发界面，压缩包已发附件，自行按前面教程配置好circuitPython的wifi设置按后面的教程做就可以了。

首先看一下成品的样子，本项目实现的内容如下：
1、使用circuitPython部署了mDNS服务，在手机端和电脑端可使用myesp32.local访问控制页面（也可以使用IP地址访问）
2、使用circuitPython实现了基于http服务，包括web控制程序的index.html等文件
3、使用circuitPython实现了用http修改LED灯状态，获取MCU温度和主频，获取sht30温湿度传感器数据







在自己的开发板上部署该服务的步骤：

1、按上一个教程的步骤，配置好wifi编辑页面，能正确访问。教程地址：https://mc.dfrobot.com.cn/thread-316202-1-1.html2、用wifi编辑页面，打开/settings.toml文件，并按以下内容调整，WIFI信息不用按图片改，改了就连不上！！！！！


3、下载附件的压缩包，并解压缩后上传至开发板上
4、使用IO0连接WS2812的IN引脚，IO4和IO5连接SHT30模块的SCL和SDA引脚
5、在手机上打开myesp32.local，就可以开始体验了
