Design And Construction Of A Digital School Bell Using Microcontroller And Timetable Display
Complete Design And Construction Of A Digital School Bell Using Microcontroller And Timetable Display Project Materials (Chapters 1 to 5):
Now a day’s many school/college bells are manually operated. Hence there is a huge demand of accuracy. In market there are many digital clocks available with bells but rings only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The benefit of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence takes over the manual task of switching on/off the college bell with respect to time. It uses Real Time Clock (DS1307) which tracks the real time. The scheduled time results are related with that of a clock, conversely, some drift is noticed, which is irrelevant. The microcontroller ATmega2560 is used to control all the functions, it gets the time through the keypad and stores it in its memory. When this programmed time equals the real time then the bell is switched on via a relay for a predetermined time. The bell ringing time can be edited at any time, so that it can be reused again and again at normal class timings as well as at exam times. Also it can be made password protected so that no unintended person can operate this system except for the operator. For this a microcontroller has to be programmed using the C language or assembly language for controlling the circuit.

INTRODUCTION
1.1 Background of the study
In today’s life, everyone gives importance to time. Time does not wait for anybody. Everything should be performed in time and 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 and 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. So it is an important instrument in both primary and secondary schools and even in the industries and other businesses where the bell timer plays a critical role throughout the day. Clock towers can be heard over long distance which was especially important in the time when clocks were too expensive for widespread use. And also due to literacy awareness the number of colleges, schools and institutions are rapidly increasing. At present bells for periods in schools are operated manually. After every class, one employee is engaged into operating the bell. Automatic college bell helps us to avoid this. This design takes over the task of ringing the bell in colleges as the bell would ring automatically at the schedule time. It has a 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 real time clock is displayed on LCD display. This is very wonderful design to control the working of college bell.
1.2 Problem Statement
School bells have been a critical part of all our childhoods which is managed, monitored, timed and always ringed by human being. As a result of the human beings’ control timing, monitoring and ringing can be wrong-timed. But with the advent of technology as many things have been digitalized the school bell has experienced technological advanced. Digital school timetable was built to overcome the challenges seen in our conventional school bell by providing the following functions:
• Storing entire day timetable with timings
• Sounding buzzer at the end of every period
• Displaying the name of current and next period
• Ability to reprogram the board at any time
1.3 Aim and objectives of the study
The main aim of this work is to build a digital school bell using microcontroller and timetable display. The objectives of the project are:
i. To build the system prototype.
ii. To Store entire day timetable with timings
iii. To ring the school at the right time
1.4 Scope of the study
The scope of this work covers building a digital school bell and schedule time display system using microcontroller using Inbuilt Real Time Clock (DS1307 /DS 12C887) 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. The microcontroller was programmed using the C language or assembly language for controlling the circuit.
1.5 Advantages of the Project
i. It is an automation system.
ii. Human errors can be avoided.
iii. Safety is assured.
1.6 Applications of the project
i. It is used in colleges, schools.
ii. Also used in industries.
ii. In railway station and airport.
iv. Digital watches, washing machine, oven.
