本源码实现的功能是有多个发光二极管做跑马灯，其中有十种亮灯模式。用专门的按键切换模式，并可以对每种模式进行亮度控制。用LED显示每种跑马灯的模式。当跑马灯处于一种模式时，伴随的音乐响起，音乐有三首并可以进行切换。压缩文件中包含了Proteus仿真文件，可直接观看效果-To achieve the functions of this source is more light-emitting diodes do marquees, including ten lighting mode. With a dedicated button to switch modes, and brightness control for each mode. LED display mode of each marquee. Marquee in a mode, accompanied by the music sounded, the music of three and can be switched. The compressed file contains the Proteus simulation file can be directly viewing
