Security is the most concern for anyone nowadays . As
the most natural way physical key is widely used to lock or unlock the
door. Different locks have different keys so it is burden to carry
,sometimes it may be stolen ,misplaced and lost. The purpose of the
proposed system is to provide extra security that can be used in homes
and services . The proposed system is OTP based smart wireless lock
system using Arduino Uno. If the user generate correct password OTP is
sent on the user’s device via Bluetooth . If the entered OTP is matched
then the system will be unlocked and required task can be initiated . If
either of the password or OTP is wrong then the access is denied . The
proposed system provides low cost service and high security compared to
the available security systems.
ABSTRACT

 The main aim for providing locks for our home, school, office etc
is for security of our lives and property. With the advancement
of technology and increase the use of IOT automatic door lock
system has become a standard feature on many different types
of buildings and homes. And they are become popular every day
to develop electronic devices which provide security.
 Home security has been a major issue because of the increase in
crime rate and everyday wants to take proper action to prevent
unauthorized user, so we propose an OTP based smart
wireless lock system to enhance the security of digital door-
locks.
INTRODUCTION

EXISTING METHOD
The electronic wireless locking system
is not that safe because you might forget
your password, or it might be hacked by
others, while entering the password on your
device.
A key-based locking system has
now become outdated because if your
key is lost or stolen, it creates a huge
problem . Carrying a large number of
keys is a burden and it can be stolen ,
misplaced or lost. So, we can make a
smart lock that has the capability to
remove all these security problems.

Our goal is to design a solution for secure access control that can replacephysical keys
for accessing door. We propose asolution using OTP based on smart phones providing
wireless and automatic unlocking
The design will allow easy
implementation and the device will work
autonomously. This will enhance the security
and will eliminate the need of carrying
physical keys.
PROPOSED METHOD
via Bluetooth.

If you are specifically working with a wireless lock system using Arduino Uno, here
are the technical skills that would be beneficial:
1.Arduino Programming: Proficiency in programming the Arduino Uno board is
essential. You should have a good understanding of the Arduino programming
language (based on C/C++), as well as knowledge of the Arduino development
environment and libraries. This will enable you to write code to control the wireless
lock system and implement desired functionalities.
2.Wireless Communication: Familiarity with wireless communication protocols is
crucial for connecting the Arduino Uno to the wireless lock system. Depending on
the specific wireless technology used (e.g., Wi-Fi, Bluetooth), you should have
knowledge of the corresponding libraries and protocols to establish communication
between the Arduino and the lock system.
TECHNICAL SKILL

3.Circuit Design and Electronics: Understanding electronics and circuit design is
important for connecting the Arduino Uno to the various components of the
wireless lock system. You should be able to read schematics, identify the required
components (e.g., relays, motors, sensors), and wire them correctly to the Arduino
board.
4.Power Management: Knowledge of power management techniques is necessary to
ensure that the Arduino Uno and the wireless lock system are powered
appropriately. You should understand how to provide power to the Arduino board,
as well as how to power the lock system components efficiently and safely.
5.Security and Encryption: Depending on the security requirements of the wireless
lock system, you may need to implement encryption and authentication
mechanisms in your Arduino code. Understanding concepts like secure
communication, encryption algorithms, and authentication protocols will help you
enhance the security of the lock system.

6.Troubleshooting and Debugging: As with any technical project, troubleshooting
skills are crucial. You should be able to identify and resolve issues that may arise
during the development and operation of the wireless lock system. Knowledge of
debugging techniques, using tools like serial monitoring, and analyzing error
messages will aid in problem-solving.
Remember that the specific technical skills required may vary based on the wireless
lock system's design and the specific components used. Make sure to refer to the
documentation and resources provided by the wireless lock system manufacturer for
detailed guidelines and specifications.

Mobile

First, we need to write a program for that we need to include the
library files . Here we include a servo library because of using the servo
motor . After writing the program let’s make Android APP i.e. the
MIT(Massachusetts Institute of Technology)app inventor. Which is used
for lock and unlock the door. Connect the components to Arduino uno and
all the components to power supply. Then we have connected all the
components.
Next, open the installed App, then turn on the Bluetooth of the
phone, tap on HC-05 module. On successful pairing, you will get a
‘connected’ message on the App. After that, tap on the key icon to send
device id to match. If the device id is matched, it will send an OTP to your
app that you can see in App text bar between Bluetooth and lock icon.
WORKING

Now, you can tap on the lock icon to unlock your Smart Lock. If
everything is ok then servo moves unlocking mechanism and onboard
LED of Arduino lights up indicating successful unlock. We have used
servo because of its high torque, and also because we can control the
angle of its movement that helps in unlocking mechanism of lock.

The figure represents that
door opens when OTP is
matches.
The fig shows that the
OTP is received to OTP
app lock in our android
mobile.

The figure shows the
circuit of the OTP

lock system using
Arduino uno.
The figure describes
that the opening and
closing the door by
the received OTP to
our mobile through
Bluetooth.
Hardware circuit
RESULT

 It has more security.
 It does not allow unknown people.
 It is also used for anti-thefting strategy.
 It reduces the efficiency of the cost.
 Simple and easy implementations.
 It has less power Consumptions.
ADVANTAGES

 Smart phone can be lost.
 Bluetooth module maybe connected to
another device.
LIMITATIONS

 Control of doors and windows shutters
 Faster operation and efficient
 Security System
This project can be used in Industries , Home,
office and Shops
 It can be used for garage doors and gates.
By using smart app , disabled or elderly people can
control lock as well as appliances anywhere inside
house.

APPLICATIONS

Many times we forgot to carry the key of our home. Or
sometimes we come out of our home and door latch
closes by mistake. In these cases it is really difficult to get
inside the house . The main proposal for this project is to
increase the extra security to the people .This project will
help in keyless entry and at the same time will be more
secure. This idea will minimize the overall cost by the use
Bluetooth.

CONCLUSION

The future scope for this is to extensions within the app
cloud also be viewing who is passing through the door by
adding the camera and sending stream directly to mobile
device.
This can also extends to , if someone is trying to break in the
door . Alarm will start beeping on mobile device .
The other extension for this project is to add a camera with
built-in SD card and also the finger print sensor
