題目五 電子拔河游戲機(jī)

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)光二極管表示拔河的“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個(gè)發(fā)光二極管時(shí)，則該方獲勝，連續(xù)比賽多局以定勝負(fù)。

基本要求：

1、設(shè)計(jì)一個(gè)能進(jìn)行拔河游戲的電路。

2、電路使用 9 個(gè)發(fā)光二極管，開機(jī)后只有中間一個(gè)發(fā)亮，此即拔河的中心點(diǎn)。

3、游戲雙方各持一個(gè)按鈕，迅速地、不斷地按動(dòng)，產(chǎn)生脈沖，誰按得快， 亮點(diǎn)就向誰的方向移動(dòng)，每按一次，亮點(diǎn)移動(dòng)一次。

4、亮點(diǎn)移到任一方終端二極管時(shí)，這一方就獲勝，此時(shí)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)。

功能：電路使用 9 個(gè)發(fā)光二極管，開機(jī)后只有中間一個(gè)發(fā)亮，此即拔河的中心點(diǎn)。 游戲雙方各持一個(gè)按鈕，迅速地、不斷地按動(dòng)，產(chǎn)生脈沖，誰按得快， 亮點(diǎn)就向誰的方向移動(dòng)，每按一次，亮點(diǎn)移動(dòng)一次。 亮點(diǎn)移到任一方終端二極管時(shí)，這一方就獲勝，此時(shí)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。用數(shù)碼管顯示獲勝者的盤數(shù)。

按鍵檢測模塊

模塊功能：按鍵按下后，輸出一個(gè)脈沖信號(hào)指示按鍵按鍵

拔河控制模塊

模塊功能：控制led燈根據(jù)按鍵移動(dòng)，左移或者右移，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個(gè)發(fā)光二極管時(shí)，則該方獲勝，此時(shí)雙方按鈕均 無作用， 輸出保持，記錄此時(shí)的分?jǐn)?shù)

顯示模塊

模塊功能：用數(shù)碼管顯示獲勝者的盤數(shù) ，分別顯示游戲雙方的或者盤數(shù)，采用掃描式的數(shù)碼管，數(shù)碼管為共陽極。
