用51單片機實現愛心跑馬燈程序

用51單片機實現愛心跑馬燈程序

本人閒來無事做，見實驗室的小夥伴用LED等做了一個跑馬燈，頓時引來了一大羣妹子，當時就不服了，哼，不就是一個流水燈，說的跟誰不會一樣

製作的是32個LED燈的愛心流水燈，至於燈怎麼安放，我就不多說了，關鍵是怎麼連接佈線。

由於條件有限，沒有製作PCB的工具，所以就用的洞洞板，32個LED共陰極，連接在51單片機的GND上，每個LED的正極分別連接單片的一個引腳，

我的所有線路全是用電烙鐵焊接的，線路醜爆了，在此就不上圖了，爲了後續程序好寫一點，LED的正極和單片機的引腳的連線最好多考慮一下

好了，廢話不多說了，直接上代碼，只做了幾個動畫，可以按照自己的想法再添加
