【K230 实战项目】气象时钟

为了方便小伙伴们理解，请查看视频
B站连接

---

功能描述：

1. 天气信息获取：通过连接到互联网，实时获取天气数据，包括温度、湿度、天气状况、风向
2. 实时时间显示：气象时钟能够显示当前的时间。
3. 可视化天气：包括城市， 温度，相对湿度，实时风向，空气质量

说明

HMDI资源

HDMI屏幕的小伙伴下载链接：K230 气象时钟文件，包含图片，字体，代码

我在此基础上做了一个HDMI的气象时钟。（为了让小伙伴多给上面的大佬点赞，我这边的资源是VIP资源。）小伙伴可以去大佬那里点赞领取代码文件。3.5屏幕的小伙伴直接使用。HDMI的，可以使用我下面的代码。（资源里都带）

使用方法

大致使用方法：

1，首先连接WIFI

输入WIFI账号密码

2，默认获取的是深圳市的气象数据

修改城市的方法也很简单，找到这段代码

把HTTP复制 在浏览器上粘贴

改一下自己想看的地方，然后吧链接替换就行
