ABSTRACT
The key for the realization of a design can be displayed properly clock / stopwatch, timer with multi-functional puter alarm clock. This article discusses the development puter clock means pared and analyzed, ultimately determined by microcontroller technology to achieve puter clock. AT89C51 chips in this design application as a core and six LED digital display hours, minutes and seconds to run 24 hours a time, using the key switch can be realized, the sub-adjust, clock / stopwatch functions of conversion and timer functions. This method provides the advantage of simple circuit, reliable performance, real good time and high precision, simple operation and programming easy. puter can be used in ordinary life and work, can also be modified to improv performance, add new features to people's life and work more convenient.
Key words: computer clock; AT89C51; LED digital tube; stopwatch
