DIY基于51單片機(jī)的旋轉(zhuǎn)LED數(shù)字電子鐘

1、標(biāo)簽： DIY基于51單片機(jī)的旋轉(zhuǎn)LED數(shù)字電子鐘(紅外線遙控調(diào)時(shí))在網(wǎng)上看到不少老外做的各種旋轉(zhuǎn)顯示屏，非常，我也動(dòng)手用洞洞板試做了一個(gè)類似的顯示屏，結(jié)果感覺(jué)還不錯(cuò)。于是再接再勵(lì)繼續(xù)努力，將作品進(jìn)一步改進(jìn)，完善后制成如今這個(gè)樣子。由于剛學(xué)51單片機(jī)，加上制作電路板軟件也是從零開(kāi)始，的確花了我不少的時(shí)間和精力。不過(guò)也就是在這艱難的獨(dú)立制作中，真正學(xué)到了不少實(shí)在的東西。本項(xiàng)目的關(guān)鍵是如何解決高速旋轉(zhuǎn)的電路板如何供電，如何調(diào)時(shí)的問(wèn)題。我采用電機(jī)電刷的原理，將旋轉(zhuǎn)軸鉆空，通過(guò)一只插頭將電源的從反面引到前面的電路板上，而這個(gè)旋轉(zhuǎn)的插頭又與固定在背板上的兩個(gè)銅片接觸的。調(diào)時(shí)的問(wèn)題有些困難，一是讓電路板在

2、旋轉(zhuǎn)前與機(jī)相接，由電腦傳送調(diào)時(shí)數(shù)據(jù)，這雖然可行但不方便。還有就是用遙控方法，但此方案在調(diào)試方面有很大的困難。顯示方式上，我采用平衡式的兩排，這除了在旋轉(zhuǎn)時(shí)能較好的保持平衡外，主要能利用兩邊交替顯示方式，比單排要快一倍。本裝置不僅是一個(gè)時(shí)鐘，它還可以動(dòng)態(tài)顯示漢字及圖案，這就看如何發(fā)揮了。其具體制作過(guò)程如下：一。旋轉(zhuǎn)電機(jī)的制作從制作成本與方便考慮，選用舊電腦用的大軟驅(qū)上的直流無(wú)刷電機(jī)，只是對(duì)局部進(jìn)行改造。                &#

6、機(jī)仔細(xì)拆開(kāi)直流電機(jī)，將帶圓盤(pán)的鋁軸從中開(kāi)孔，讓它剛好能插入一個(gè)插頭。                                            &#

12、作本制作品用單片機(jī)控制，具體電原理圖如下： 用Protel 99設(shè)計(jì)制作了電路板。  最后得到完成的作品。 遙控器用的是松下車載機(jī)的，只用了其中的六個(gè)鍵。  三。軟件編程因?qū)W的是（不懂匯編）這里只提供語(yǔ)言源程序，并限制為無(wú)遙控功能。也可提供帶遙控功能的hex文件。        #include <reg51.h>sbit gate11=P30;sbit gate12=P31;#define unit unsigned int#define u
