Now, the electronic clock is human the most basic, most essential as a tool. In the last century, most electronic clock use is separation of components. And this produced electronic clock bulky, use is also very troublesome. Along with the rapid development of science and technology and electronic industry, now circuit are height integrated. Not only save space resource, cost is also very low. Although electronic products to our life brought more convenience. Procedures will be used in the design of the main control system is a single chip, using its own timer design. SCM has low cost, the volume is small, easy to operate, etc.. It can form a variety of automatic control system. The design uses a microcontroller is the most typical and I were in the classroom study of 51 series microcontroller, the design STC89C51 microcontroller as the core to the clock chip DS1302 as the basis, by means of a peripheral small amounts of key circuit real-time calibration through LCD1602 LCD display to display the date and time. In part, I use C language to write. The use of C language is more conducive to my understanding, writing and revision. This paper mainly from the selection of the design scheme of the system, hardware, software part of the description and physical demonstration up detailed d
