The aim of this project is to develop an embedded system to create a programmable automatic college bell system using Real Time Clock operation (RTC). This project is built around 8051 architecture based microcontroller with RTC, alarm, LCD display, etc. A real-time clock (RTC) is a computer clock to track of the current time. This Project takes over the task of Ringing of the Bell in Colleges. It replaces the Manual Switching of the Bell in the College. It has an Inbuilt Real Time Clock (DS1307) which tracks over the Time. When this time is equal to the Bell ringing time, then the relay for the bell is switched on using the driver circuit. The Bell Ringing time can be edited at any Time, so that it can be used at Normal Class Timings as well as Exam Times. The Real Time Clock is displayed on LCD display. The Microcontroller is used to control all the functions; we can set or adjust the time through the keypad and store it in its Memory. And when the Real time and Bell time get equal then the Bell is switched on for a predetermined time.
