ABSTRACT
Consider a scenario of a paraplegic person who is on the bed reading a book and
wishes to close the door because of the noise outside. The old system would
probably comprise of calling someone either the maid, or relative etc. to close
the door. This project aims to automate many of the home items by the use of
voice. It can be implemented using an embedded system such as a processor
capable of processing natural languageand amechanicalsystemtocausemotion
on the item accordingly. For a user of the system, all the person would need to
do is give commands like “Open Door”, “Close Door” etc. and the door would
perform motion as per the instruction. To demonstrate the concept, we are
automating the closing and opening of curtains purely based on voice
instructions. Here, voice is taken as input by a microphone, sent to a processor,
and is processed.
This project is based on upcoming technologies and has wide scope throughout.
Appropriate changes will have to be made depending upon the application and
mechanical system used for the implementation but the core concept remains
using voice as input to automate items, in particular household items.
KEYWORDS: Arduino, Natural language processing, Bluetooth module, BroXCode

INTRODUCTION
This project has certain objectives that will be explained in
detail further. The motion of curtains usingnaturallanguage
processing is a hardware oriented project. It was initially
designed to overcome the difficulties of the disabled or
paraplegic community in our society. This kind of motion is
not only confined to the curtains alone, but it can be
implemented anywhere, in all aspects of our daily life. The
limitations for movement in a disabled person make them
unable to do even the minute works in one’s life. In order to
overcome such difficulties, we can automate all the home
systems. Among this curtains are also a matter of concern.
Also consider the situations of large indoor stadiums with
windows at great heights. Extensivelabour andtimemust be
invested in such situations. Then also it is a matter of
concern to close such windowblindsorcurtainsmanually.In
such circumstances motion of curtains/windowblindsusing
natural language processing becomes relevant. The scope of
this project is wide and can be modified extensively in
various automation methods and also adapted to suit
multiple environments. It can be controlled using the voice
commands by the user. The same idea can be used to
implement automation in all othersystemsthatworksonthe
basis of motion. Here we use Arduino to automate the
curtains / window blinds which can cause motion. We are
using Arduino as the microcontroller and Embedded C to
program the hardware. The voice is received using the
microphone (Smart phone for the time being used as
microphone.) An app is used to convert the voice commands
into text and the same is transmitted to the input port of
Arduino using a bluetooth module. The two servo motors
used to move the curtains in a particular degree are
controlled using the Arduino. It is an overall cost effective
implementation which is affordable and can becontrolled by
everyone. The setup cost may initially be a bit high, but in
the long run it is expected that there will be a reduction in
both electricity and paper cost.
EXISTING METHODOLOGY
Before the development of the advanced features that are
seen and used nowadays, it was very difficult for a
paraplegic person to move as theyalwaysneededsomeone’s
help. For example, to adjust the curtains as per their
requirements and so on. The limitations for their motion
made them unable to do even the minute worksneeded fora
healthy satisfying life and so they werealwaysdependent on
someone and they needed manual help.
This was the most common method used before any
development in advanced technology.

Advantages:
Here manual help is used. (Eg. Asking someone to do it
for you.)
No use of any technology.
No use of electrical or some other sources of energy
here.
Disadvantages:
Always there has to be someone to help out the person
to perform their necessary task due to their limitations.
Emotional discomfort
PROPOSED SYSTEM
The currently methodology is completely based on home
automation. Our newly proposed system is capable of
overcoming all the disadvantages of the previously existing
solution. These newly applied technology provides more
advantages due to its useful features. Here we have focused
on movements of curtain for a paraplegic person for
demonstrative purposes. As a paraplegic/old/disabled
person cannot perform these tasks like opening door,
curtains etc. The technique of automation can be used to
help them perform some of the necessary work or tasks by
themselves. Here, we are applying motion using natural
processing language which is comes under home
automation. We are using Arduino as the microprocessor
and Embedded C to program the hardware. The voice is
received using the microphone (here, we are using
Smartphone) and with the help of some applications we can
convert the voice commands into text and the same is
transmitted to the input port of Arduino using a Bluetooth
module (for large scale usage we can use Wi-Fitoo). Here we
have used two servo motors which helps the movements of
the curtains in a particular degree and it can be controlled
using the Arduino.
Advantages:
No need of depending anyone
Makes a person independent.
It is reliable.
Purely controlled by voice
The concept can be expanded to other spheres of home
automation.
Disadvantages:
It can be costly.
Cannot be used in situation where voice signal is
unavailable.
COMPONENTS
1. Arduino UNO –
It’s the most commonly used version of Arduino Boards.
Arduino UNO is a microcontroller based on ATmega328. It
has 14 digital Input/Output pins out of which 6 are PWM
outputs. There are 6 analog inputs. It has a powerjack,aUSB
Connection, 16 MHz quartz crystal, a reset button and an
ICSP header. ICSP (In Circuit programming) is a protocol
used for programming the microcontroller using another
Arduino or to connect it to a computer to upload the
program.
2. Jumper Wires –
They are wires which can be used to join two points in a
circuit board without soldering. There are 3 types: (i) Male
to Male jumper wire, (ii) Female to Female jumper wire and
(iii) Male to Female jumper wire.
3. Polystyrene (Thermocol) –
It can be hard and brittle. It’s an aromatichydrocarbonmade
from styrene monomer. In this project, It’s with the help of
thermocol, a lightweight chassis of the curtain was made.
4. Synthetic Ribbon –
Servo Motors were used to rotate the curtains. It cannot
rotate heavy materials and hence the cloth material used in
the curtain was fancy synthetic ribbon.
5. Servo Motors –
They are DC motors that allows precise angular positioning
of items. They have a revolution of 90, 180 or 360 degrees.
They are small in size and energy efficient. However, they
don’t have enough strength to handle the weight of real long

curtains. Here in this project we are using one servo motor
to demonstrate the voice automation. To handle higher
loads, a Stepper motor can be used. It has 3 lines.
WORKING
The system is designed simply by use of a small
microcontroller, interfaced with the system and connected
on a breadboard. The system comprises simply of an object,
which in our case turns out to be a blueprint of acurtain. The
curtain is made to rotate enough to lift its blinds or close
them. The motion is achieved through using servo motors.
The servo motors are programmed using Arduino IDE and
the circuit board used Arduino UNO. Since it is voice
controlled, Microphones provided in smart phones are used
and an android app published by BroXCode is used to
convert audio to text. Thisis transferred viaBluetooth HC-05
bluetooth transceiver toArduino. Theaudioisprocessed and
the motion is set.
The language used for coding is EmbeddedCand thisproject
is mainly hardware. It is implemented by arranging things
appropriately. The program is written on Arduino IDE.
The hardware code is loaded into RAM of Arduino. The
program ran perfectly and caused the desired motion. It has
been tested under various scenarios like under noise, range
etc. The testing also included giving random voice
commands, recorded voicecommandswithdifferentdialects
etc. and the system developed proved effective.
Program:
//Arduino IDE code
#include <Servo.h>
Servo servoright;
int i;
intposl = 0;
intposr = 270;
void setup() {
Serial.begin(9600);
servoright.attach(9);
i = 1; }
void openc() {
servoright.write(posr);}
void closec() {
servoright.write(posl);}
void loop() {
if (i==1){
servoright.write(270);
i=i-1; }
if (Serial.available())
{
char s = Serial.read();
if (s == 'a')
Serial.print("opened");
openc(); }
else if (s == 'b') {
Serial.print("closed");
closec(); }
}}

OUTCOME
There are mainly two outcomes are expected from the
project. We have collected few data from the electric
department and the help from our department for obtaining
the required results. Our project aims to automate home
items such as closing of curtains based on natural language
processing (NLP). It can be implementedusinganembedded
system having a Natural Language Processor to process the
voice signals and an ioT based systemtocausemovementon
the curtains. It can be designed to minimize the human
efforts to interact with the other systems. By achieving this,
the system will make human life comfortable. It mainly
consist of four phases. Firstly, we are sending audio signals
to microphone. Then the audio signals are transferred
through bluetooth module. This module transfers data to

Arduino for data processing. Arduino gives the commands
for motion through the servo motor for causing the motion
of curtains. Acknowledgement We acknowledge our
