Electronic clock is mainly the use of electronic technology to make the clock electronic and digital, with clock accuracy, small size, friendly interface, strong scalability and other characteristics, is widely used in life and work. In addition, in life and industrial and agricultural production, temperature is often needed, which requires the versatility of the electronic clock.
The main purpose of this design is to realize a multifunctional electronic clock that can display clock\/calendar normally and has a timing alarm.
The development methods of electronic clock are compared and analyzed, and the multifunctional electronic clock is realized by single chip microcomputer technology. This design uses AT89C52 chip as the core, 6-bit LED digital tube display, and uses DS1302 real-time clock calendar chip to complete the basic functions of clock\/calendar. The advantages of this method are simple circuit, reliable performance, good real-time performance, accurate time, simple operation and easy programming.
