This document presents an Arduino-based home automation system using Bluetooth. It introduces the project, includes a block diagram, lists the hardware requirements, and describes the process for making a relay circuit. It explains the components used - Arduino UNO, Bluetooth module, relay, transistors and resistors. Software used is Arduino IDE. Advantages are convenience and energy savings. Disadvantages include limited range and number of devices controlled. Future work proposes using Ethernet and WiFi for remote control from anywhere.

- 11. ARDUINO UNO •The Arduino Uno is a microcontroller board based on the ATmega328P. •It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. •Simply connect it to a Computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

- 19. SOFTWARE USED PROGRAMMING LANGUAGE ARDUINO IDE EMBEDDED C/C++
- 20. ADVANTAGES • It is a robust and easy to use system. • It will save your energy and money. • Provides Security. • Convenience and comfort. • Can be used by physically challenged and disabled people. • Complexity is less as only a single mobile is used multiple devices. • Smart home technology.
- 21. DISADVANTAGE S • Only works for limited range or short distance with in 5-10m surroundings. • No feedback path. • Number of appliances which can be controlled through this circuit are limited. • Circuit complexity increases as number of devices increase.
- 22. FUTURE WORK •This setup can further be developed into IOT project by using Ethernet arduino and a wifi module. •So , it can be controlled from anywhere around the globe having feedback from the devices to further improve the energy savings.
