Automatic college bell system

Abstract:

The world over the decades has made considerable advancement in automation; automation is
employed in every sector whether it is home or industry. Here a new and inexpensive design is being
presented. This design finds a tremendous use at primary and secondary school levels as well as in colleges
where the teaching sections can span over eight periods including breaks. The advantage of this design is
that the bell rings at the start of each period without any human intervention to a great degre ....etc

The project is designed to automatically operate an electric bell several times as required in an educational institution like school or college. It overcomes the difficulties of switching the bell on/off manually. This proposed system has an inbuilt real time clock (RTC) to keep a track of the time and thus to switch on/off the load accordingly.

The project uses a real time clock (RTC DS1307) interfaced with the microcontroller of the 8051 family. While the set time equals to the real time, the microcontroller gives command to the correspon ....etc

description of real time clock based on automatic college bell ringing system

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 Real Time. When this time equals to the Bell Ringing time, then the Relay for the Bell is switched on.
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 pi ....etc

Abstract

The main aim of this Automatic College Bell using RTC ECE Project is to design an automatic college bell system for colleges and schools.

This project has done in the period of 3 months for my final year project submission in my college. This electronics project going to automatically ringing the bell at a correct time replacing manual switching including RTC. This circuit has a built-in Real Time Clock which tracks over the real time. When this time is equal to that of bell ringing time, the relay for the bell is switched on. This ....etc
