1、 LED搖搖棒的詳細制作資料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】。 黑暗條件下拍攝的效果圖片： 實物外形圖:基本原理與硬件電路設(shè)計： 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點陣的顯示有幾分相仿。 硬件電路如下圖（點擊可放大）。系統(tǒng)電源VCC為5V，下載程序和調(diào)試時一定要保證5V電壓，實際使用時用3節(jié)干電池串聯(lián)4.5V即可。AT89S52單片機

2、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，由單片機輸出低電平點亮。P0口的上拉電阻RA1不能少。串在LED公共端的二極管D1會產(chǎn)生一定的壓降，用來保護LED，經(jīng)實測LED點亮?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：棒在搖動時，只能在朝某一方向搖動時顯示，否則會出現(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時將內(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，遠看效果很好但近看時字不夠連貫。建議使用直徑為3mm的高亮LED，顏色可根據(jù)個

3、人喜好選擇。水銀開關(guān)里的水銀珠很活躍，導(dǎo)致在接通時容易產(chǎn)生抖動，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：IC座里面隱藏元件，既美觀又能保護元件：軟件設(shè)計：/*程序名稱：LED搖搖棒顯示64*16像素簡要說明：外部中斷方式INT0顯示；取模方式：縱向取模、字節(jié)倒序編 寫：JiangX.net最后更新：08/11/15晚*/#include #define uchar unsigned char#define uint unsigned int/宏定義#define KEY P3_0/定義畫面切換按鍵uchar KY;/KY作用在后面說明uchar disp
