ds18b20

单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)
