奋斗了两晚上，最终在张老师的帮助下实现了微博提醒器的原型。
功能如下：
1. 自动获取IP
2. 获得微博状态并显示在点阵LED上
电路连接如图

//How to use this?
//Just use the software named "ArduinoFrameAnimator" to export the "animation.h" file.
//Then Copy to this Tab"animation.h" and Upload.
//The main sketch don't need to change anything! The animation will loop playback itself
//Only if you want to add some action in loop(). Have fun!

楼主
额，忘记加了。 你也是用Yeelink做的？响应快么？
