AUTOMATIC COLLEGE BELL
Abstract
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 four 7-segment display. The Microcontroller
AT89S8252 is used to control all the Functions, it get 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.

This Project takes over the task of Ringing of the Bell in Colleges. It

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 four
7-segment display. The Microcontroller AT89S8252 is used to control all the
Functions, it get 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.
Today is
the world of atomization. Microcontrollers and embedded systems have made lot
of things automatic and easy to use.
We are
developing the system which will be used as college bell. In this system we
will use RTC for time keeping purpose .The bell will be ringing according to
time set by the keypad. LCD will be used to display current time as well as
different settings. Buzzer will turn on according to the time settings at
different intervals.
