- 1. ARDUINO –BLUETOOTH BASED HOME AUTOMATION PRESENTATION BY Sourav Roy (59) Saswata Baral (07) Aqsa Nasim Khan (41) Shoumosree Mondal (46)
- 2. INDEX • INTRODUCTION TO THE PROJECT • HARDWARE REQUIRED • BLOCK DIAGRAM • PROCESS OF MAKING RELAY CIRCUIT • SOFTWARE USED • ADVANTAGES • DISADVANTAGES • REFERENCES
- 3. INTRODUCTION 1. To develop a Bluetooth based home automation system with Arduino-UNO Board and an Android application. 2. Remote controlled home automation system provides a simpler solution with Android application technology. 3. Remote operation is achieved by any smart phone/Tablet etc.
- 4. HARDWARE REQUIREMENTS • Arduino UNO • Bluetooth Module -HC-05 • 12V Relay • Smart Phone • LED Lights • Power Supply 230v,50Hz. • Switch board
- 7. 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 ARDUINO UNO

- 10. BLUETOOTH MODULE For the communication between mobile phone andmicrocontroller Bluetooth module (HC-05) is used. HC-05 is low power 1.8V operation and is easy to use with Bluetooth SPP (serial port protocol).
- 12. RELAY Relay is basically an electromagnetic switch which can be turn ON and OFF by applying the voltage across its contacts. In this project we used a 12V 5 pin relay
- 14. SOFTWARE USED PROGRAMMING LANGUAGE ARDUINO IDE EMBEDDED C/C++
- 15. 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.
- 16. DISADVANTAGES 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.
- 17. 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.
