AWTRIX2.0像素时钟很炫酷但必须要与服务器配合使用。这个库可以做自己的点阵时钟离线版。想怎么玩就怎么玩不受服务器牵绊。
第一步：下载mixy库然后倒入，必须有以下库文件： Adafruit_GFX FastLED FastLED_NeoMatrix TomThumb
#include //LDR光敏电阻
#include
#include
#include
#include //字体库
特别说明TomThumb 字体必须用下载包里的字体，用原Adafruit_GFX字体效果很难看。

上测试时效果图：

需要的硬件：
WS2812软点阵屏 32X8 256灯珠。

以上全部齐全后即可开整！先看库使用程序图。一看即懂。
垂直线：
