In today's life, traditional mechanical locks can no longer meet the needs of modern people. In order to improve the performance of mechanical locks to meet people's needs, electronic locks have emerged. Electronic coded locks generally use single chip microcomputer as the core component. Compared with other components, single chip microcomputer has great advantages, which can not only realize software and hardware analysis, but also design and debug. So as to realize the intelligent control of the electronic coded lock by using the singlechip. The combination lock has t...
