原理圖.doc

要求：通過8只連續排列的發光二極管的依次點亮代表“乒乓球”的運動，中間兩個綠燈表示擋板，其余為紅燈。再用兩個按鍵模擬左右兩個球拍，鍵按下代表球拍擊球。“左拍”按下可使發光二極管從左向右依次點亮，如同“乒乓球”從左向右飛來；“右拍”按下則可使發光二極管從右向左依次點亮，代表“乒乓球”從右向左運動。在游戲過程中，用數碼顯示管實時顯示雙方比分。游戲規則如下：
（1）“乒乓球”移動速度是固定的，設定每秒鐘移動一位（發光二極管）。
（2）在“乒乓球”移位一次的過程中，進行25次的測試（即每40毫秒一次），查詢接球方是否有擊球動作。
（3）接球方的擊球動作應發生在“乒乓球”到達本方最后一位發光二極管（即點亮）一秒鐘時間之內。如接球方在此一秒鐘之內按鍵，則接球成功，接球方得分。“乒乓球”轉為相反方向運動。此后，原接球方變為發球方，原發球方變為接球方。游戲繼續進行。
（4）如接球方提前或滯后擊球，則接球方失誤。雙方都不得分。這時“乒乓球”熄滅，數碼顯示管顯示雙方的比分不變。然后仍由原發球方發球。

程序有些亂，請大家幫我改改，幫我做出完整程序流程圖。
希望各位高手幫幫我！
