Watches digital has brought great convenience to peoples production and living, and greatly expanded the original watch function. Such as digital clock, calendar, electronic watches, timed automatic alarm, timed to open and close circuits, open and close the power equipment, even a variety of timed electrical auto-enabled, communications, networking and many other fields, all of which are based on watches digital. Increasing its functionality, ease of use continue to increase, many products have become an indispensable assistant to human daily life. This article is based on single chip microcomputer control of digital clock system design. This system mainly by the single-chip microcomputer AT89C51 as the core in combination with key choice module to control the digital tube display and buzzer module work, so as to realize the clock and alarm clock function, and can be on the clock and alarm clock, minutes and seconds to individually check, make the correction to standard time. This design in order to control the hardware and software and hardware combined with software as the guiding ideology, give full play to the MCU function. At the same time, the digital clock system also has the characteristics of low consumption, low cost, strong practicability. Due to the function of the system is simple, thus has certain extensibility.
