旋轉(zhuǎn)的led時鐘

1、電氣工程及其自動化創(chuàng)新設(shè)計設(shè)計名稱： 旋轉(zhuǎn) led 時鐘班 級： 姓 名： 學(xué) 號： 指導(dǎo)老師： 設(shè)計時間：2009年9月2號8號茂名學(xué)院計算機與信息學(xué)院自動化系 旋轉(zhuǎn)的時鐘一、原理分析 旋轉(zhuǎn)時鐘利用了視覺暫留原理。用led燈排成一列，取中間一點為圓心，他們圍繞圓心旋轉(zhuǎn)，最外側(cè)的發(fā)光二極管顯示時間刻度，當(dāng)時針在12點時我們假設(shè)角度為0º，則每個小時時針之間的角度為360º/12=30º.于是當(dāng)這一列發(fā)光二極管每旋轉(zhuǎn)30º，最外側(cè)的發(fā)光二極管就點亮一個瞬間一呈現(xiàn)時間刻度。這樣，如果在0.1s內(nèi)這列發(fā)光二極管能旋轉(zhuǎn)完一圈，則人眼就會產(chǎn)生錯覺，而把先后產(chǎn)生的時

2、間刻度連成12個完整的時間刻度。明確系統(tǒng)功能 系統(tǒng)的功能比較清楚：電機帶動一系列發(fā)光二極管繞軸旋轉(zhuǎn)，單片機控制發(fā)光二極管在旋轉(zhuǎn)過程中的相應(yīng)位置上點亮以指示時間和刻度，與此同時，單片機內(nèi)部進(jìn)行時鐘的計時操作，以控制旋轉(zhuǎn)時鐘顯示正確的走時。這種利用機械的帶動分時顯示數(shù)據(jù)信息的方法叫做機械掃描顯示。硬件設(shè)計 旋轉(zhuǎn)時鐘主要有兩部分組成：電機部分和單片機控制發(fā)光二極管顯示部分，在單片本制作品用單片機控制，具體電路原理圖如下：軟件編程因?qū)W的是（不懂匯編）這里只提供語言源程序，并限制為無遙控功能。也可提供帶遙控功能的hex文件。
