名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)
