Currently, SCM principles and application materials are mostly using assembly language to explain the design process instance, but assembly language learning difficulties. In the development and debugging of the practical application of the system, especially the development of complex application systems in order to improve development efficiency and make the program easy to transplant, now more than using C language. In the rapid development of the information industry today, our lives will not need equipment toward miniaturization, portable, intelligent, automated direction. Electronic password lock came into being with the fast-paced life. Equipped with a lock in a key of the sixties and seventies, or traditional, whether units or individuals every day carefully check whether the door is locked, and the keys can not misplacing once accidentally forget where to put very might not open the door. The traditional lock considerable unsafe, there will be some unscrupulous elements tried their best to open your room lock to steal things. Generation of electronic password lock so that these issues are no longer a problem, we simply need to remember th
