Automatic School Bell

Automatic School Bell?

Introduction

In today’s life, everyone gives importance to time. Time does not wait for anybody. Everything should be performed in time & with accuracy. Now a day’s school/college bells are operated manually. Hence there is a big question of accuracy. Also there is necessity of manpower and money. Hence here we have presented a system, which saves our manpower and money & also give highest accuracy. A bell is a percussion instrument used in schools and colleges that Indicates the students when it is time to go to the class in the morning and when it is time to change classes during the day. No other instrument can do such a work.

Overview

This circuit uses a programmed microcontroller chip to schedule the school teaching and break periods so that for every start or end of a period a bell is automatically rang. The controller can be triggered by time or any desire input such as sensor, keypress, or specific action. The device is designed to provide totally independent multi-schedules; every schedule has a separate output where a different alerting sound can be used for easy sound identification. The basic design of the Automatic School Bell in this work remains the same though extra functions can be included. This will ring the School Bell at pre scheduled times of periods on each day. There are different times per period varying from one school to the other. The basic design provides an opportunity of selecting the suitable time schedule for every school by momentarily pressing one of the push to on switches. This signals the microcontroller to carry out the specific task, thereby ringing the bell at a regular time interval.
