Abstract - This paper presents a low cost flexible and
reliable home automation system with additional
security using Arduino microcontroller, with IP
connectivity through local Wi-Fi for accessing and
controlling devices by authorized user remotely using
Smart phone application. The proposed system is server
independent and uses Internet of things to control
human desired appliances starting from industrial
machine to consumer goods.The user can also use
different devices for controlling by the help of web-
browser, smart phone or IR remote module.To
demonstrate the effectiveness and feasibility of this
system, in this paper we present a home automation
system using Arduino UNO microcontroller and the IC
ATmega328 as a connectivity module. It helps the user
to control various appliances such as light, fan, TV and
can take decision based on the feedback of sensors
remotely. We have testedour system through conducted
experiment on various environmental conditions.

1. INTRODUCTION
IOT or internet of things is an upcoming
technology that allows us to control hardware devices
through the internet. Here we propose to use IOT in
order to control home appliances, thus automating
modern homes through the internet. This system uses
four loads to demonstrate as house lighting. Our user
friendly interface allows a user to easily control these
home appliances through the internet. For this system
we use an Arduino board.Arduino is interfaced with a
WIFI module to get user commands over the internet.
Also we have an LCD display to display system status.
Relays are used to switch loads. After receiving user
commands over the internet, microcontroller
processes these instructions to operate these loads
accordingly and display the system status on an LCD
display. Thus this system allows for efficient home
automation over the internet.
2. DISCRIPTION
As we are using Arduino Uno. It is a popular
opensourcesingle-boardmicro-controller,descendant
of the open-source Wiring platform, designed to make
the process of using electronics in multidisciplinary
projects more accessible. The hardware consists of a
simple open hardware design for the Arduino board
with an Atmel AVR processor and on-board
input/output support. The software consists of a
standardprogramminglanguagecompilerandtheboot
loader that runs on the board. Arduino hardware is
programmed using a Wiring-based language (syntax
and libraries), similar to C++ with some slight
simplifications and modifications, and a Processing-
based integrated development environment.

4. ARDUINO UNO
Arduino is an open source computer hardware
and software company, project, and user community
that designs and manufactures single-board
microcontrollers and microcontroller kits for building
digital devices and interactive objects that can sense
and control objects in the physical and digital world.
The project's products are distributed as open-source
hardware and software, which are licensed under the
GNU Lesser General Public License (LGPL) or the GNU
General Public License (GPL), permitting the
manufacture of Arduino boards and software
distribution by anyone. Arduino boards are available
commercially in preassembled form, or as do-it-

yourself (DIY) kits.Arduinoboarddesignsuseavariety
of microprocessors and controllers. The boards are
equipped with sets of digital and analog input/output
(I/O) pins that may be interfaced to various expansion
boardsorBreadboards(shields)andothercircuits.The
boards feature serial communications interfaces,
including Universal Serial Bus (USB) on some models,
which are also used for loading programs from
personalcomputers.Themicrocontrollersaretypically
programmed using a dialect of features from the
programming languagesCandC++.Inadditiontousing
traditional compiler tool chains, the Arduino project
provides an integrated development environment
(IDE) based on the Processing language project.

5.PROPOSED SYSTEM
IOT or internet of things is an upcoming
technology that allows us to control hardware devices
through the internet. Here we propose to use IOT in
order to control home appliances, thus automating
modern homes through the internet.The system
consists of Arduino uno board, relays, wifi module esp
8266, loads,lcd display.This system uses four loads to
demonstrate as house lighting.We are used Ubidots as
iot platform. We can add switches there one for each
load.The Arduino reads the status of the switches on
the Ubidots dashboard consistently over the internet
through wifi module. According to the status of the
switches Arduino turn on or off the loads. Also it will
display the status of the loads on the lcd. In this way,
the loads in the home can be operated from anywhere
in the world using iot technology over the internet.
6.EXPERIMENTAL RESULTS
The IOT system we have developed is tested in
different load conditions for few houses . After
installing the experimental setup, the user needs to
install the software tohis/herlaptoporandroidphone.
After proper installation of the provided software
the16X2 LCD display will show the IP address. After IP
address and port address are obtained user can login
from the android application.As soon as the setup is
completed, a home page will appear, from which the
user could keep a track of all the electronic and
electrical devices which are connected with theserver.
7. CONCLUSION AND FUTURE SCOPE
In this paper wefocusedondifferentprocessof
operating or controlling electrical and electronic
appliances remotely with the help of Arduino. This
method of controlling such applications is referred to
as automation. The experimental setup which we
designed has its focal point on controlling different
home appliances providing 100% efficiency. Due to
advancement in technology, Wi-Fi network is easily
available in all places like home,Office Building and
Industrial Building so proposed wireless network
easily controlled using any Wi-Fi network. The wiring
cost is reduced. Since less wiring is required for the
switches. This also eliminates power consumption
inside the building when the loads were in off
conditions. This system is also platform independent
allowing any web browser in any platform to connect
ESP8266-01.The system is fully functional through
android application known as “ESP8266 Wifi control”.
The delay to turn ON is 3 sec and turn OFF is 2 sec for
any load. For future use, the researchers would
recommend as : (i)Reducing the time delay to turn on
and off of an appliance (ii) Adding speech recognition
to the system (iii)using automatic smart phone
detection through Wi-fi such that it will operate the
loads automatically when it is in range.(iv) Expansion
of range of Wi-Fi such that one can operate in
permissible long distance through smart phone.
