Description: 采用at89s52和液晶模拟数字密码锁的所有功能,具有密码保存的功能.程序运行后首先提示输入密码，密码输入正确则8X8LED开始模拟霓虹灯闪烁 密码输入错误则提示重新输入密码直到正确为止。按下设置键可对密码进行设置。设置密码首先输入旧密码，旧密码输入正确则可以继续进行下面的操作旧密码输入错误则提示旧密码输入有误，旧密码输入错误次数达到三次,则提示输入错误达到最大允许次数，此时不能再尝试对密码进行设置。 另外为了操作上的直观 ，屏幕上显示的密码为明码，在现实生活中是不允许的，读者可尝试在输入密码时屏幕上显示"*"符号-Using at89s52 and LCD analog and digital lock all the features with a password save function. Program runs after the first prompt for a password, the password you enter the correct password 8X8LED started flashing neon analog input error is prompted to re-enter the password until the correct date. Press the Set key to set the password. To set a password first enter the old password, enter the correct old password, you can continue to operate below the old password input error is prompted to enter the old password is wrong, the old password input error number has risen to three times, then prompts to reach the maximum allowable number of input error, this time can not be and then attempt to set the password. In addition to intuitive operation, the screen displays the password as plain language, in real life is not permitted, readers may try to enter the password displayed on the screen when the "*" symbol
