随着微机测量和控制技术的迅速发展与广泛应用,以单片机为核心的电子密码锁的设计研发与应用在很大程度上改善了人们的生活,尤其是在一些公共场合(比如大型超市)保存私人物品等方面起到了不可估量的作用。本设计论述了一种以STC89C52单片机为主控制单元,以LCD1602为显示器件的电密码锁系统。该控制系统可以每次随机生成四位数的密码,并显示在LCD上,用户记住改密码后进行输入并核对是否正确。系统设计了相关的硬件电路和相关应用程序。硬件电路主要包括STC89C52单片机最小系统,LCD显示电路、LED指示电路,按键电路等等。系统程序主要包括主程序,密码生成和校验程序、LCD显示程序以及按键模块程序等。 基于单片机的密码锁设计与实现(proteus + 源代码)
