Introduction: 

This pro#ect has integration of 

An$roi$ "o%ile technology an$

e"%e$$e$ syste". An$roi$ "o%ile

user has to install an application on

his "o%ile han$set to control the

$e&ices. Then he she can gi&e

co""an$ using the %uttons on that

application. 'or this you ha&e to turnon the (luetooth on "o%ile) so the

"ain ireless controlling techni*ue

use$ in this pro#ect is (luetooth

technology. (luetooth recei&er ill

 %e connecte$ to the pro#ect. This

(luetooth $e&ice is connecte$ to the

circuit hich has a $eco$er. It sen$s

out a co$e for respecti&e co""an$

sent %y user. Then the respecti&e

$e&ice connecte$ to the circuit ill

 %e turne$ on or off $epen$ing on the

co""an$ gi&en. 'or e+a"ple, Turn

on light) Turn off light. Turn on fan

etc. Such that %y gi&ing co""an$s

fro" "o%ile you can control ho"e

appliances.

Project Description,

  This pro#ect "ainly consists of 

folloing %loc!s 1. An$roi$ "o%ile

-. (luetooth recei&er unit 3.

icrocontroller 4.Poer supply unit

/. C isplay 2. elays .

5utput $e&ices.

Android:

An$roi$ %y si"ple $efinition) is an

operating syste" for "any "o%ile

 phones. 

An$roi$ is a custo"i6a%le

 platfor" that can loo! an$ feel &ery

$ifferent on e&ery $ifferent han$sets.

An$roi$ gi&es us tools for creating

apps that loo!s great an$ ta!e "ore

a$&antage of the har$are

capa%ilities a&aila%le on each$e&ice. An$roi$ is "ainly %ase$ on

inu+ operating syste" hich uses

 #a&a7 li!e languages for running

applications. The purpose of use of 

an$roi$ in our pro#ect is to sen$ the

control signals fro" s"art phone

through %luetooth.

Bluetooth:

o$ule (luetooth as selecte$ as

our ay of co""unicating "o%ile

ith a central syste". (luetooth"o$ule recei&es the $ata serially in

S-3- for"at fro" controller an$

sen$s it to ireless netor!. 'or 

interfacing it ith "icrocontroller 

e nee$ to %uil$ the circuit %ecause

(luetooth "o$ule un$erstan$s $ata

in S-3- stan$ar$ an$ controller 

un$erstan$s $ata in TT for"at. So

e nee$ to $esign circuit to "a!e

these to co"pati%le ith eachother.

Microcontroller:

80/1 icrocontroller can %e use$ as

the %rain9 to control a large &ariety

of pro$ucts) in or$er to control large

$e&ices. In our pro#ect e use$ 80/1

"icrocontroller. The 80/1

"icrocontroller co""unicates ith

the (luetooth "o$ule . The serial

control co""an$ sen$ through the

s"art phone is recei&e$ %y the

(luetooth "o$ule an$ processe$ %y

80/1 "icrocontroller. The

correspon$ing port pins are ena%le$

to sitch on an$ off appliances.

power supply unit,

egulate$ poer supply is use$ to

 pro&i$e $esire$ $c poer to the

80/1 "icrocontroller.

Relay: 

The relay $e&ice is use$ ith the

househol$ electronic or electrical

appliances hich acts as 5: ; 5''sitch.

Adantages: 

1.Can control $e&ice fro" a long

$istance) thus it gi&es ease of access.

-. 'aster operation an$ efficient. 3. :o nee$ to carry separate re"ote or 

any other controlling unit.

!uture scope: 

This pro#ect can %e further 

$e&elope$ %y integrating it ith the

internet to "onitor your ho"e hile

sitting in a re"ote area. (y $oing

this) one can !eep an eye on his or her ho"e through an internet

connecte$ to the user s "o%ile‟ phone or PC or laptop. This ill not

only i"pro&e the security of your 

ho"e in this "o$ern $ay.

 Applications:
