This article is designed to achieve a multi-functional digital clock, and its function as follows: a 24-hour hour, minute, seconds display, with the whole point timekeeping function year, month, day and week s calendar display with a stopwatch function can shows the current ambient temperature through key information on the time to adjust. AT89C52 single-chip computer system as the master chip. System module used to achieve LCD1602 LCD Monitor. LCD1602 can display two lines of characters, 16 characters per line, to meet the requirements of the system display. The temperature acquisition system DS18B20 chip modules. DS18B20 small size, its output is digital, can be directly related to single-chip communications, and send a single bus, simplifies the circuit, greatly reducing the system size. System Clock Generation Module DS1302 clock chip used. DS1302 clock chip to send a single bus, just a line can be completed with the exchange of data between the single-chip, and the high accura
