INTRODUCTION
 In
this project Bluetooth module is interfaced to 8051
microcontroller.
 This Bluetooth receives the commands from the
Android
application
device
using
wireless
communication.
 The
program which is written to the 8051
microcontroller communicates with Bluetooth module
serially to receive the commands.
 Microcontroller
switches the electrical loads
automatically based on the commands received from the
Bluetooth
MOTIVATION
Disabled people are more likely to be exposed to daily life
problems than other healthy people. While deaf people cannot
hear the door bell, Alzheimer diseased people can forget the gas
open in the kitchen.
 These are some encountered examples when they 4 are alone at
home. With the help of technology, assistant projects can be
developed to overcome their difficulties.
 Smart homes can also be used to support disabled people,
providing safe, secure and empowering environments. The system
can allow the user to control many features or automate them.
 The environment can also be monitored by the smart home
system to ensure safety and alert people when there is some
dangerous situation.

OBJECTIVE
 To
design an efficient Bluetooth control home
appliance. So it can be easy to On or Off any
electronic appliance like fan,lamp etc.

ALGORITHM
Initialize the LCD and UART protocol.
 Now read the data from Bluetooth module.
 Display the received data on LCD.
 Compare the received string with predefined strings and
accordingly switch the electrical loads.
 Display the status of electrical loads on LCD.

COMPONENT FUNCTIONS/SPECIFICATION
Bluetooth module
 The Bluetooth module used in this project is HC-05
Linvor Bluetooth module.
 It is an easy- to-use Bluetooth serial port protocol (SPP)
module, designed for a transparent wireless serial
connection set-up.
 The module has 34 PINS for configuration/interfacing of
Bluetooth module with microcontrollers.
For setting up a Bluetooth module.
LIQUID CRYSTAL DISPLAY (LCD)

Most Common Lcds Connected To The Microcontrollers Are
16x2 And20x2 Displays.

This Means 16 Characters Per Line By 2 Lines And 20
Characters Per Line By 2 Lines, Respectively.

Our Project It Will Be Display Status Of The Lamp Or Motor,
On Or Off
PLANNING OF THE WORK
First we aware with all the components
 We can implement the power supply.
 We can implement the microcontroller.
 We can interface lcd with microcontroller
 Then we interface Bluetooth with microcontroller
 We work on programing.

SUMMARY

In this project we can make the Bluetooth control home
appliance .
