This document describes a home automation system that allows remote control of electrical equipment through the internet using an Arduino board. The system uses an Arduino UNO board connected to an Ethernet shield and WiFi network to control appliances through a web interface. It aims to provide a cheap, open source, and easy to use system for remotely controlling and automating home appliances from any internet-connected device.

2. AIM
• The project aims to establish control
of electrical equipments remotely
through Internet by using Embedded
Technology.

3. OBJECTIVE
• To design and to implement a cheap and open source
system that is capable of controlling and automating
home appliances through an easy manageable web
interface.
• The proposed system has a great flexibility by using WiFi
technology to interconnect its distributed modules to
server. That will decrease deployment cost and will
increase the ability of upgrading, and system
reconfiguration.
• System will make use of secure wireless LAN
connections between distributed hardware modules and
server, and secure communication protocols between
users and server.

4. Hardware Requirements
• Arduino UNO R3 board
• Arduino Ethernet Shield
• WiFi network
• Relay Board

5. Software Requirements
• The Arduino software, built using C language, using IDE
comes with the microcontroller itself.
• A browser enabled device must be in the range of the
wireless network in which the system is deployed.

6. ARDUINO UNO R3
• Microcontroller: ATmega328
• Operating Voltage: 5V
• Input Voltage: 7-12V
(recommended)
• Input Voltage (limits):6-20V
• Digital I/O Pins: 14 (of which 6 provide PWM
output)
• Analog Input Pins: 6
• DC Current per I/O Pin: 40 mA
• DC Current for 3.3V Pin: 50 mA
• Flash Memory: 32 KB (ATmega328) of which 0.5 KB
used by bootloader
• SRAM: 2 KB (ATmega328)
• EEPROM: 1 KB (ATmega328)
• Clock Speed1: 6 MHz

14. IMPLEMENTATION STEPS
• Implementation details:
• Wire up the Arduino board
• Open arduinowifi.ino in the Arduino development tool
• Enter the name and password for your Wi-Fi network in arduinowifi.ino
• Upload the program to the Arduino
• Open the Serial Monitor Window and look for the IP address of the Arduino. (If the IP address is
not displayed, check your Wi-Fi network name and password)
• Run the Arduino Workbench on your desktop/laptop computer and Make theAndriod App.

15. • Run the client app on an mobile device and connect to
the Workbench
• Launch the example "Arduino LED On/Off TCP" from the
Workbench window
• Enter the IP address of the Arduino
• You should now be able to turn the LED on and off using
the buttons in the device

16. SUMMARY
• Controlling Electrical Equipment through WiFi is a cheap
home automation system that is developed using open
source Arduino technology. The system is very user
friendly, Its design is simple and is easy to use.

17. Advantages
• Makes the switching control easy and convenient for
Physically Disabled people
• Saves electricity
• Man-power utilization is reduced
• More powerful then Bluetooth technology
• More range than Bluetooth technology

18. FUTURE WORK
• Replacement of Ethernet shield by Wi-Fi shield
• Add features of login authentication to access the
system
• Development of Android application and for other mobile
platforms
• Implementation of various sensors such as temperature
sensor and light sensors
