Design of a High Precision Digital Clock Based on Single Chip Microcomputer

Compared with traditional mechanical clocks, digital clocks have higher accuracy and durability and are widely used in people's daily lives.This paper designs a digital clock which uses AT89S52 single-chip microcomputer as the main control chip.It can count hours, minutes, and seconds, and can calibrate the time.It can switch between 24-hour and 12-hour systems.As a smart clock, while displaying the time, it also adds the function of temperature display.The intelligent digital clock designed in this paper has stable performance in theory and has certain practical value.
