電子拔河游戲機(jī)是一種能容納甲乙雙方參賽游戲電路。由一排發(fā)光二極管表達(dá)拔河的“電子繩”。由甲乙雙方通過按紐開關(guān)使發(fā)光二極管向一方的終點(diǎn)延伸，當(dāng)延伸到某方的最后一種發(fā)光二極管時，則該方獲勝，持續(xù)比賽多局以定勝負(fù)。

基本規(guī)定：

1、設(shè)計(jì)一種能進(jìn)行拔河游戲的電路。

2、電路使用9個發(fā)光二極管，開機(jī)后只有中間一種發(fā)亮，此即拔河的中心點(diǎn)。

3、游戲雙方各持一種按鈕，快速地、不停地按動，產(chǎn)生脈沖，誰按得快，亮點(diǎn)就向誰的方向移動，每按一次，亮點(diǎn)移動一次。

4、亮點(diǎn)移到任一方終端二極管時，這一方就獲勝，此時雙方按鈕均無作用，輸出保持，只有復(fù)位后才使亮點(diǎn)恢復(fù)到中心。

5、用數(shù)碼管顯示獲勝者的盤數(shù)。

2.設(shè)計(jì)框圖譯碼器編碼電路選擇開關(guān)整形電路可逆計(jì)數(shù)器控制電路圖1.拔河機(jī)游戲機(jī)框圖二、設(shè)計(jì)環(huán)節(jié)和調(diào)試過程1、總體設(shè)計(jì)電路總體電路圖和仿真圖如圖(25)所示，由仿真圖可知，此電路設(shè)計(jì)無誤，能夠?qū)崿F(xiàn)按動A、B兩個按鍵時，分別產(chǎn)生兩個脈沖信號，經(jīng)整形后分別加到可逆計(jì)數(shù)器上，可逆計(jì)數(shù)器輸出的代碼經(jīng)譯碼器譯碼后驅(qū)動電平批示燈點(diǎn)亮并產(chǎn)生位移，當(dāng)亮點(diǎn)移到任何一方終端后，由于控制電路的作用，使這一狀態(tài)被鎖定，雙方按鍵產(chǎn)生的輸入脈沖不起作用。如按動復(fù)位鍵C，亮點(diǎn)又回到中點(diǎn)位置，再次按C鍵則比賽又可重新開始。
