随着生活节奏的加快，人们时间观念的加强，时钟已经成为人们日常生活中不可或缺的一部分，而如何在时钟的基础上，根据人们生活的需要增加相应的功能以方便人们的生活，成为时钟设计方面的重点。单片机以其强大的功能，低廉的价格成为许许多多功能电子产片的首选。本设计结合所学的单片机的原理与应用而扩展的电子方面的研究，在单片机时钟的基础上通过软件记时，实现时钟功能，同时通过安检开关来扩展功能，实现定时闹钟与秒表功能。C语言作为高级语言C语言的移植，易于理解和操作，且结构化较高，本设计即采用C语言作为编程语言，流程比较清晰，。

With the acceleration of life rhythm and the strengthening of people's time concept, the clock has become an indispensable part of people's daily life. How to add corresponding functions to facilitate people's life based on the clock and according to people's life needs has become the focus of clock design. With its powerful function and low price, single chip computer has become the first choice of many multifunctional electronic chips. This design combines the principle and application of the single-chip microcomputer and the electronic research of the extension. On the basis of the single-chip microcomputer clock, it realizes the clock function through the software time recording, at the same time, it expands the function through the security check switch, and realizes the function of the timing alarm clock and the stopwatch. C language as a high-level language C language transplantation, easy to understand and operate, and highly structured, this design uses C language as the programming language, the process is relatively clear,.<br>
