| Abstract: | This electron clock is connected to the MCU AT89C51 by the 12MHZ crystal oscillator.With software programming,the clock can display hour,minute and second at the same time in a 24-hour cycle.It can give correct time with a buzzer when it is on the hour.This kind of electron clock is equipped with three keys,S1,S2 and S3,which enable the clock to adjust to keep accurate time and to buzz at the set time. |
