適用班級：電子A1621
注意事項：
1. 課外開放設計，開卷考核，可查閱任意資料。
2. 單人考核，獨立完成，如有雷同，一律0分。
3. 不允許對電路圖做任意形式修改。
4. 提交以“電子A1622_01_陳**_期中測試”格式命名的項目文件夾。
電路如圖所示，設計程序實現如下功能：
1. 能根據交通規律正確設置交通燈狀態及數碼管顯示內容（60分）
2. 能手動調節時間（30分）
3. 能根據交通狀況自動延長直行時間；（10分）

注：通過鍵盤調節時間項目中，分為東西直行時間、
東西左轉時間、南北直行時間、南北左轉時間4個項目，
每個項目7.5分，小數點四舍五入。

1. 模式鍵用來選擇設定的時間，如東西直行時間、南北左轉時間等。
時間加減鍵用于手動調節直行時間，每按鍵一次加減5s。
2. 交通繁忙探頭用于探測道路交通狀況，如果當前道路排隊較長，
則繁忙探頭返回0，可臨時延長當前方向直行通道時間10s，一個
紅綠燈周期最多延長3次。本設計用邏輯狀態輸入端口模擬。
