Embedded Based Automatic College Bell System
Abstract
Embedded Based Automatic College Bell System project is
developed for the users to control Bell system in companies or institutions
automatically. All the bell timings and durations are predefined and set in the
microcontroller.
The user can set the timings using a key pad. A LCD display
is used to display the timings. The timings set by the user are stored in the microcontroller.
At the particular time, signal is generated in the
microcontroller and sent through the output port. The electronic circuit
receives the signal and drives a corresponding relay. The relay is used as a
switch to operate the Bell. As soon as the duration is over, the signal is
stopped and waiting for the next set time.
This system is mainly used in Schools, Colleges and other
companies where Bell system is implemented. There is no need of a person
managing the bell timings. The microcontroller program is written in Assembly Language.
The microcontroller used is PIC 16F73.
