用51单片机实现爱心跑马灯程序

用51单片机实现爱心跑马灯程序

本人闲来无事做，见实验室的小伙伴用LED等做了一个跑马灯，顿时引来了一大群妹子，当时就不服了，哼，不就是一个流水灯，说的跟谁不会一样

制作的是32个LED灯的爱心流水灯，至于灯怎么安放，我就不多说了，关键是怎么连接布线。

由于条件有限，没有制作PCB的工具，所以就用的洞洞板，32个LED共阴极，连接在51单片机的GND上，每个LED的正极分别连接单片的一个引脚，

我的所有线路全是用电烙铁焊接的，线路丑爆了，在此就不上图了，为了后续程序好写一点，LED的正极和单片机的引脚的连线最好多考虑一下

好了，废话不多说了，直接上代码，只做了几个动画，可以按照自己的想法再添加
