说明：  密码锁 本次课程设计的题目是：《基于单片机和串行EEPROM组建的电子密码锁》。设计该电子密码锁是利用我们的51学习板、LCD液晶显示器模块、以及AT24C02的EEPROM来完成的，具有LCD的显示和修改密码的功能，密码能实时保存在EEPROM中。
(The curriculum design is entitled: " Based on MCU and serial EEPROM organized electronic code lock." The design of the electronic code lock is to use our 51 study panels, LCD liquid crystal display module, and the EEPROM AT24C02 accomplished with LCD display and modify the functions of the password, the password stored in the EEPROM in real time.)
