基于单片机开发设计单列LED显示模块，以时移控制LED输出内容，通过人眼的视觉暂留效应，在LED转动区域产生一个扇形视觉平面，从而达到在该视觉平面上传达信息的作用，实现广告信息显示。系统可通过232通讯接口更新显示内容。

-Based on MCU development and design single LED display module to the time shift control LED output by the human eye persistence of vision effect, turn the LED produces a fan-shaped area in the visual plane, so as to achieve convey information on the visual plane role in achieving ad information display. The system can display the contents of the update via the communication interface 232.
