2. INTRODUCTION:
• In today's life, everyone gives i. mporta.nce to time. time
does not wait for anybody.
• Everything
should be performed in time & accurately. Now
a day's school or colJege bells are manually operated.
• Hence there is a big question of accuracy. Also there is
necessity
of manpower and money.
• Hence here we should
use automatic control system, which
saves
our manpower and money & also gives highest
accuracy, Hence we have
selected the project.

3. OBJECTIIVE:
• The main objective of this project is to implement Automatic college
bell
on a ARDUINO UNO Board.
•
the prima.ry objective of designing this project is to reduce the human
intervention for the purpose of manual switching operation of a bell.
• Because
of this manual switching we are not sure about the accuracy of
the time.
• So, a system should be designed in such a way that it is exactly
dependent on real time clock and the switching of the bell should be
contro!Ued automatically without human intervention.

4. What is the need of a bell?
• Generally, wherever we may go, it might be a school or an organisation
if start or stop of any process is to be conveyed to a large number of
people, a bell is used over there which signals the start or stop of any
process.
So, simply a bell is used to give indication about the beginning or
termination of any process.
Ho\v is it operated?
• From olden days to till today we are still dependent on manual
switching operation of a bell with the help of a person.

5. Disadvantages of manual switching:
• Accuracy is reduced
• Waste
of man power
• Waste
of money
Need for automation:
• Increased throughput or productivity
• Improved quality
or increased predictability of quality.
• Improved robustness (consistency),
of processes or
product.
• Increased consistency
of output.
• Reduced direct
human labor costs and expenses.

7. COMPONENTS INVOLVED IN THIS DESIGN:
• PC
• ARDUINO SOFTWARE.
•
ARDUINO UNO BOARD.
• BUZZER (OR) BELL.
• LCD
MODULE FOR DISPLAY OF DATE AND TIME.
• POWER
SUPPLY.
• LM386 AUDIO AMPllFrER.
• SPEAKER

8. FUNCTIONING PROCESS:
• Create a new project in ARDUINO and then write the code for the
design to be implemented
•
As the bell is dependent on real time clock for its functioning as per the
given schedule,
firstly, we have to make use of a RTC-DS1307 module
to implement the functioning
of the bell,
•
Based upon the timing mode of RTC ,a schedule is assigned in the code
itself for the bell to ring
at some regular intervals of time without
human intervention.
• After the code is written, check for errors and then upload it
on to the
ARDUINO
UNO board and verify the functioning of the designed
circuit by checking the output.

9. ADVANTAGES:
• This project can be used in educational institutes, colleges, schools.
• Automatic scheduling
of bell is possible in the code itself directJy.
• This project can also be used in industries.
•
Human errors can be avoided.
• It
is an automatic system.
• Safety is assured.
• Cost
is less.

10. APPLICATIONS:
• Can be used in schools or colleges or any other organizations
• Washing machines
• Microwave ovens
• Video recorders
• Security systems
• Digital watches.

11. CONCLUSION:
• Presenl day ringing 1he bell in colleges or schools arc carried o ul manually.
So this should be eliminated comple1ely by making use of automation.
• The m
oin disadvantage of this is thot one person hos to be olert for this and
the probability of error is more.
• To overcome this,
we have decided to prepare the circuit which wi ll be
operated automatically and the ringing
of bell will slart by its given time.
