LED搖搖棒的詳細(xì)制作資料

1/1LED搖搖棒的詳細(xì)制作資料LED搖搖棒的制作大家知道，人的眼睛存在視覺暫留現(xiàn)象，正因?yàn)檠劬Φ姆磻?yīng)遲鈍，才豐富了人的視覺感受。

LED搖搖棒很好地利用了人眼的視覺暫留特性。

下圖是基于51單片機(jī)控制、16只高亮度LED發(fā)光二極管構(gòu)成的搖搖棒，配合手的左右搖晃就可呈現(xiàn)一幅完整的畫面，可以顯示字符、圖片等。

演示效果見自制LED搖搖棒展示【圖】。

實(shí)物外形圖:基本原理與硬件電路設(shè)計(jì)：

16只LED發(fā)光管作為畫面每一列的顯示，左右搖晃起到了掃描的作用，人眼的視覺暫留現(xiàn)象使得看到的是一幅完整的畫面。

與LED點(diǎn)陣的顯示有幾分相仿。

硬件電路如下圖（點(diǎn)擊可放大）。

系統(tǒng)電源VCC為5V，下載程序和調(diào)試時(shí)一定要保證5V電壓，實(shí)際使用時(shí)用3節(jié)干電池串聯(lián)4.5V即可。

AT89S52單片機(jī)作為控制器，在它的P0、P2口接有16只以共陽的方式連接的高亮度LED，由單片機(jī)輸出低電平點(diǎn)亮。

P0口的上拉電阻RA1不能少。

串在LED公共端的二極管D1會(huì)產(chǎn)生一定的壓降，用來保護(hù)LED，經(jīng)實(shí)測(cè)LED點(diǎn)亮?xí)r兩端電壓為3V左右，在LED的安全承受范圍內(nèi)。

K1是畫面切換開關(guān)，用于切換顯示不同內(nèi)容；S1為水銀開關(guān)。

水銀開關(guān)的作用：

棒在搖動(dòng)時(shí)，只能在朝某一方向搖動(dòng)時(shí)顯示，否則會(huì)出現(xiàn)鏡像字或鏡像畫面，所以通過接一只水銀開關(guān)來控制，使搖搖棒從左向右搖動(dòng)時(shí)將內(nèi)容顯示出來。

硬件制作：

使用的是直徑5mm的紅色高亮LED，感覺太大了些，遠(yuǎn)看效果很好但近看時(shí)字不夠連貫。

建議使用直徑為3mm的高亮LED，顏色可根據(jù)個(gè)人喜好選擇。

水銀開關(guān)里的水銀珠很活躍，導(dǎo)致在接通時(shí)容易產(chǎn)生抖動(dòng)，所以將水銀開關(guān)斜向上放置（尖尖朝斜上方45角），靠水銀珠自身重力的作用減少抖動(dòng)：

IC座里面隱藏元件，既美觀又能保護(hù)元件：
