This design is the programmable controller design schedule, by the microcontroller AT89C51 chip and LCD, LED display, complemented by the necessary circuitry to form a four-way adjustable microcontroller clock. According to the given time analog control, radio, playing on a school bell, lighting controls (on-screen display), along with date and clock display. In this design is mainly used to carry out regular AT89S51, four key functions are: to adjust the settings to limit the time/time, display time alarm setting/adjusting, and set the alarm time/setting, alarm clock replacement .
