This article discusses the development of computer clock means were compared and analyzed, ultimately determined by microcontroller technology to achieve intelligent computer 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. The computer can be used in ordinary life and work, can also be modified to improv performance, add new features to peoples life and work more convenient.
