電路描述：
安全是我們?nèi)粘５纳钪凶铌P(guān)心的問題。 每個人都覺得安全問題是非常至關(guān)重要的，在家里的門和安全，可以盡可能多的安全。 為了對于門訪問安全
因此，我們打算通過引進(jìn)一個電子密碼鎖系統(tǒng)，該系統(tǒng)包括一個人得到一個訪問某些項目之前要輸入密碼的安全性，以及在家里，一個房間密碼鎖系統(tǒng)，不只是普通的單用戶密碼鎖系統(tǒng)，需要用戶插入已編程的代碼來訪問一個房間; 它是一個密碼鎖系統(tǒng)，有密碼而且可以啟用多個用戶訪問。
在基于51單片機(jī)的門儲物柜，只允許授權(quán)人員進(jìn)入限制區(qū)域的門禁系統(tǒng)。 該系統(tǒng)由8位微控制器AT89C2051具有ROM的2K字節(jié)的程序存儲器完全控制。 該系統(tǒng)具有通過該密碼，可以通過它來輸入鍵盤。 當(dāng)輸入的密碼與存儲在存儲器中的口令相等則門被打開。 如果我們輸入了錯誤的密碼超過三次，然后報警接通。
LCD的數(shù)據(jù)引腳連接到P1口和RS，R / W，E引腳連接到P0.2，P0.3，P0.4。 L293D采用旋轉(zhuǎn)電機(jī)打開和關(guān)閉更衣室。 A 4 * 3鍵盤用于輸入數(shù)字0到9，“*”，“#”。 有一個系統(tǒng)菜單，包含了開放式儲物柜三個按鈕，重設(shè)密碼，并關(guān)閉了更衣室。
