微處理器實作: AT89S52 迷你俄羅斯輪盤(電子骰子)遊戲

        既然我們會控制四個七段顯示器、按鍵，也會播放音樂，而且知道timer和中斷如何運作，那麼來製作一個小遊戲應該部會太困難吧?! 是的，集合之前練習所獲的相關知識，確實已經可以來做個遊戲試試看。

         這個遊戲很簡單，利用三個七節顯示器的六個小方格當俄羅斯輪盤，讓玩家先選擇一個方格(編號1~6)，然後再用亂數讓目標方格跑動，如果目標方格和玩家選擇的方格重合，則玩家贏得此局比賽，當然選擇的時候要有按鍵音，目標方格跑動的時候要有跳格音效，中獎後也要有慶祝動畫和音樂(超級馬力歐)囉! 雖然這個遊戲很簡單，但是已經具備娛樂軟體的雛型，製作過程還蠻有樂趣的 !!! 你也可以試試看。
