world of Intelligence in the form of Intelligentmirrorswhich is
an amalgamation of both the computer aided information
services and mirror being provided to the user as a user
interface. The credit is given to the microcontroller cards on
board, that connects to the internet, access and processes the
data and displays it effectively on a place prescribed in the
mirror. The mirror is further being intellectualized with the
addition of an input device the ALEXA. In the scope of study,
the intelligent mirror system thus developed includes features
such as weather reports, date and time information, current
news updates and greeting messages. Additional commands
are given to the system by the input voice commander the
ALEXA that can perform various tasks from playing a video of
your choice to showing maps of desired location.
Key Words: Smart mirror, Raspberry pi 3b+, Makers, IoT
1.INTRODUCTION
INTERNET OF THINGS or known as IOT is an ecosystemthat
connects various physical components together that are
accessible through the internet. The ‘thing ‘in IoT couldbe in
reference to the automobiles with their built in sensors or
the ultimate challenge the Humans with a heart monitor. A
single line explanation would be any object that has been
specified an IP address which has the ability to accumulate
and transfer data across any or specified network without
human intervention. The ability of the system to interact
with the external environment or theinternal statesisdueto
its embedded technology that also plays a key role in
decision making. The combination of IoT and Android is
employed in this system.
2. OBJECTIVE
The objective wherein is to develop a mirror thatdoessmart
activities like showing weather, time , date and news etc.
thus keeping the user away from time consuming activities.
All of the above-mentioned tasks are to be performed with
the help of the Raspberry pi 3b+.
3. PROBLEM STATEMENT
The major problem of any existing mirror is displaying just
the object in front of it or just the human face withouthaving
to interact with them. This project is developed with the
intention that people spend quality time in front of the
mirror.
4. BRIEF DESCRIPTION OF THE PROJECT
The entire system can be precisely divided into three major
sections being:
The LED monitor
The Raspberry Pi 3B+ and
Acrylic mirror
Brief description of this components is given below.
4.1 RASPBERRY PI 3B+
Fig 1: Raspberry Pi 3b+ model
This credit card sized Raspberry Pi 3b Plus is capable of
doing a lot of things and anything when compared with
desktop PC.
It has a quad core of 1.2 gigahertz,64 bit CPU,
Processor-Broadcom of BCM 2837
RAM-1GB RAM

Other Components-
BLE that is Bluetooth low energy with30pinextendedGPIO,
4 pole stereo output,
Video port that is composite,
High-definition multimedia interfaces,
camera serial interfaces,
Display serial interfaces and
Upgraded switched micro USB power source that is used for
storing data up to 2.5A.
Raspberry Pi capabilities are expansive which can be used
for word processing, for playing mini craft or web surfing or
even acting as a media player. Their extensive capabilities
are just not ending here. They are also used for streaming
blue Ray quality videos. These are the best options to
incorporate to any of your next embeddeddesignsprojectas
they provide space for 40 pin GPIO header that in turn gives
you access to 27 GPIO, 12c, UART as well as 3.3 volt and 5-
volt power supply.
4.2 LED MONITOR
LED monitors are flat panel display which uses array of light
emitting diodes in the form of pixels for video display.
There allowed to be used in the outsource because of the
brightness where the can be visible to the sun store signs
and billboards.
They have paved their way into the destination signs on
public transport vehicle as well as variable messages signs
on highways.

4.3 MIRROR
Fig 3: Mirror Functionalities
The mirror is bidirectional initially it doesnot matterwhich
side you are looking from. The light passes equally in both
directions. However, to achieve the desired effect one side
must be kept dark while the other is bright. The backside of
the mirror will be coated in black to simulate the darker
room. The monitor creates light on its own so its screen
contents will be able to shine through from the dark side. By
using a black and white interface only the white color will
travel through themirror.However,themirrorwasdesigned
to be highly modular allowing replacing most of the
hardware. They exist in both acrylic and glass. Acrylic is
potentially cheaper and easier to work with than glass.
Alternatively, there also exists two-wayfilmthatcanbeused
on ordinary windows to achieve the same effect.
5. HARDWARE REQUIREMENTS
5.1 ALEXA
Alexa is a virtual digital assistant developed by Amazon for
its Amazon Echo and Echo Dot line of computing devices.
Alexa’s capabilities mimic those of other intelligent
assistants such as Apple Siri, Microsoft Cortona, Google
Assistant and Samsung Bixby.
Alexa responds to voice control by returning information on
products music, news, weather, sports and more. The back-
end engine for Amazon’s Alexa running on Amazon Web
Services in the cloud, enabling Alexa tolearnanindividual or
family’s preferences and expand its functionality over time.

6. SOFTWARE REQUIREMENTS
6.1 RASPBIAN OPERATING SYSTEM
Raspbian Is the Best All Around Operating System.Raspbian
is the official operating system of the Raspberry Pi and
because of that, it's the one most people will want to start
with. Raspbian is a version of Linux built specifically for the
Raspberry Pi. Raspbian is a free operating system based on
Debian optimized for the Raspberry Pi hardware. An
operating system is the set of basic programs and utilities
that make your Raspberry Pi run.
There are few steps that may apply for installation this
Smart Mirror by using Raspberry Pi.
 Firstly, install the Raspbian Jessie, then boot the Pi.
Unmounts the SD card from your computer and
insert it into your Pi. Connect your keyboard,
mouse, HDMI cable and, lastly, the Pi's power cable.
 You will now see the Raspbian Pixel desktop (GUI).
This Smart Mirror needs to be Wi Fi enabled so that
it can connect to the internet and so that access is
remotely done through VNC Viewertosetthingsup.
In the top right of your screen, click on the network
icon (two computers with an X).
 Select your network enters your WIFI password,
and click OK. The Raspberry Pi 3b+ and Raspberry
Pi Zero W have built in Wi Fi. After that, find the IP
address so thus can be connect to it from any
regular computer and complete the restinstallation
from there.
 Lastly, Smart Mirror is started on system boot with
appearing of all features that include.

6.2 ALEXA VOICE SERVICES
ALEXA Voice Services (AVS) is one of the products of
Amazon services are built around AI voice controlled
assistant for various thingssuchassystemrequirements and
system Smart Home Smart Mirror as Smart Mirror. AVS and
ALEXA first introducedtoEcho,intelligentspeakercompany,
allowing two way voice interaction with multiple systems in
the environment and online. ALEXA is available in the
growing number of other devices, including smartphones,
tablets and remote controls. ALEXA was chosen as the name
for this voice service because ALEXA refers to the ancient
Library of Alexandria known as the keeper of all knowledge.
6.3 VNC VIEWER
VNC Viewer VNC stands for Virtual Network Computing and
has been developed by far flung console consoles for
penetration and hacker testers. RFB protocol are used by
VNC to send screen pixel data between device such as
computer and laptop or smartphone through internet
network and the used of the IPaddressthatalreadyavailable
in the Raspberry Pi to monitor the Smart Mirror. It isaneasy
and powerful protocol created by Real VNC. VNC Server
captures desktop computers in real time and sends them to
VNC Viewer for display. VNC Viewer collects input (mouse,

keyboard, or touch) and sends it to VNC Server to inject and
completely reach remote control. By utilizing this VNC
Viewer facility, users can control the desktop remotely by
using various electronic devices such as smartphones.
6.4 JSON
JSON or JavaScript Object Notation is a light weight text
based open standard designed for human readable data
interchange. Conventions used by JSON are known to
programmers, which include C, C++, Java, Python, Perl, etc.
 JSON stands for JavaScript Object Notation.
 The format was specified by Douglas Crockford.
 It was designed for human readable data
interchange.
 It has been extended from the JavaScript scripting
language.
 The filename extension is. json.
 JSON Internet Media type is application/json.
 The Uniform Type Identifier is public. json.
 JSON is easy to read and write.
 It is a lightweight text-based interchange format.
 JSON is language independent.
6.5 OPEN CV
OpenCV (Open Source Computer Vision Library) is an open
source computer vision and machine learning software
library. OpenCV was built to provide a common
infrastructure for computer vision applications and to
accelerate the use of machine perception in the commercial
products. Being a BSD licensed product, OpenCV makes it
easy for businesses to utilize and modify the code.
OpenCV is written in C++ and its primary interface is in C++,
but it still retains a less comprehensive though extensive
older C interface. There are bindings in Python, Java and
MATLAB/OCTAVE. The API for these interfaces can be found
in the online documentation. Wrappers in other languages
such as C#, Perl, Ch, HaskellandRubyhavebeendevelopedto
encourage adoption by a wider audience.
Since version 3.4, OpenCV.js is a JavaScript binding for
selected subset of OpenCV functionsforthewebplatform. All
of the new developments and algorithms in OpenCV are now
developed in the C++ interface.
6.6 ALEXA SKILLS
The Alexa Skills Kit (ASK) is a collection of self service
APIs, tools, documentation, and code samples that makes it
fast and easy for you to add skills to Alexa. ASK enables
designers,developers,andbrandstobuildengagingskillsand
reach customers through tens of millions of Alexa enabled
devices.WithASK,youcanleverageAmazon’sknowledgeand
work in the field of voice design.
An Alexa skill includes a voice user interface, or VUI, to
understand customer intents, and a backendcloudserviceto
process intents and tell Alexa how to respond. You can use
capabilities in the Alexa Skills Kit to deliver both.
Alexa converts spoken words to text using automatic
speech recognition (ASR), deduces the speaker’s meaning
using natural language understanding (NLU), and provides
the underlying customer intent your skill. With ASR, voice
technology can detect spoken sounds and recognize them as
words. ASR is the cornerstone of the entire voice experience,
allowing computers to finally understand us through our
most natural form of communication: speech.
Today’s voice first technologies are built with NLU, which is
artificial intelligence centred on recognizing patterns and
meaning within human language. When a computer
understands what you mean to say withoutyouhavingtoask
it in one specific way, using your voice starts to feel like
having an actual conversation.
7. IMPLEMENTATION
STEP 1:
Turn on the supply of both raspberry and LED Monitor
STEP 2:
Turn any Hotspot and connect it with raspberry Pi
STEP 3:
Now to Monitor the raspberry pi connect your device to
raspberry through VNC Viewer it requires an IP address so
we have to enter the correct IP address of raspberry pi so it
will be get connected
STEP 4:
After the proper connection, open terminal and type
-nps start
STEP 5:
The smart mirror is displayed on the mirror throughtheLED
Monitor.
It displays the Date, news, Weather, Schedules in your
calendar.
Through Alexa we can even open browser and play all the
videos and songs and read the document.
The scrolling down or up of the browser page can also be
done by using certain commands to our Alexa.

8. CONCLUSIONS
The Smart Mirror that is used here makes our lives even
easier by implementing the smart Alexa. Here the Alexa
helps us to open the browser, whichcanopenthedocuments
or an article through the voice commands. The highlight of
this smart mirror is, by using the Alexa skills we cansimplify
and use the mirror in a smart way and efficient way.
Alexa Skills can be altered in future for further
implementation of making the smart mirror function
efficiently and smartly.
The Alexa and the Raspbian component can be alone taken
out and be fixed to any other devices to make it more
interactive and smarter instead.
Example: we can use these components in car mirror, which
makes the driver to interact with his/her mirror without
using their phones on hand and get distracted while driving.
