Portable Wireless Notice Display Using Raspberry-PI
1 like63 views
This document describes a portable wireless notice display system using a Raspberry Pi. The system allows notices to be wirelessly transmitted from a Raspberry Pi transmitter and received and displayed on smartphones within a Wi-Fi range of up to 30-50 meters without internet access. The Raspberry Pi acts as a server storing notice files and using its onboard Wi-Fi capability to establish an access point. Smartphones can then access and display the notices by connecting to the Raspberry Pi's Wi-Fi network and accessing the notice files through a web browser. The system provides a digital alternative to traditional paper-based notice boards.

Abstract: Notice Board is commonly used in a variety of
institutions which we come across on a daily basis. Also, it is
the best place to put on any kinds of information, but
sticking or pinning various notice day to day is a difficult
process. A separate person is required to look after this
notice-board. Due to this there is wastage of things like
paper, printer-ink and loss of time. This project idea is about
innovative wireless Noticeboard. The project is created with
the help of ARM-controller raspberry-pi 3 model B, which is
the heart of the system and it acts as a transmitter which
send notices. It has inbuilt Wi-Fi, which provides Wi-Fi range
up to 30-50 m. At a receiving end any smartphone can
receive notices this whole process is done without the
internet.
Key Words: System, Web Browser, Raspberry-Pi, SD-Card,
Electronics Components.
1. INTRODUCTION
Notice Boards are an important medium for
displaying information and keeping people aware. The
traditional notice boards involve the pinning up of printed or
handwritten information on a board. The digital electronics
notice board is speedy alternative than the ordinary type of
notice board [1]. This idea can display multiple notices at a
time to the number of users. This idea with an aim to increase
the usability of electronic notice boards, deals with wireless
reception and display of notices using Raspberry-Pi.
Notice-board is a thing that can be used in multiple
places like any institution or public utility places [4]. The way
to digitize the notice board is necessary because traditional
notice-board required, separate person for pinning or sticking
notices on the board and wastage of paper printer-ink etc.
A WI Fi is used for data transmission that is sending
notices we are using raspberry-Pi model B as transmitter by
using raspberry-Pi we can make notices in any format and
stored in appropriate folder as a database of server to the
transmitter over Wi-Fi at receiving end after establishing
connection between the transmitter (raspberry-pi) and
receiver (smartphone) by providing local host address then
we are able to access the notices which is stored in the
database of their server [2]. And the overall process is off line.

Description: Notice Board is the primary thing in any
institution or public utility places like bus stations, railway
stations, colleges, malls, etc. But sticking various notice day to
day is a difficult process. A separate person is required to take
care of this notices display. This project is about innovative
wireless notice board. A Wi-Fi is used for sharing Data. At any
time we can add or re- move or alter the information (notices)
according to our requirement. Legal PC is used for sending
notices at the side of the transmitter. And Wi-Fi is used for
sharing data at the receiver side. When an authorized user
sends a notice from his system, it is received by the receiver.
Wireless is a well-known technology that allows an electronic
device to share data wirelessly over a computer network,
including high speed wireless connections.

Fig.4. Establishing of Access Point
In the above figure, Raspberry Pi 3 Model -B has inbuilt Wi-Fi
i.e. 802.11n as ‘n’ indicates then n-input and n-output
because of this feature it can convert Wi-Fi to Access Point for
sharing notices as server to the clients.
Fig.5. Installing Apache Server
For sharing notices we require the Data Base to store the files
and File Transfer Protocol to share files over Local Area
Network (Wired or Wireless). So, for this purpose, we have
Apache Server as File Transfer Protocol. Installation of
Apache Server is shown in the above figure-4.After
successfully installing Apache Server then, obtaining the IP
address by passing command “ifconfig” in command-line-
terminal window. After that establishing connection between
server as Raspberry Pi and clients as Smart Phones.
Fig.6. Display Notices on Smart Phones
Now open any browser in smart phone and then put the URL
as whatever the IP address (Wlan) generated by the
connection established with the server. As the arrow
indicated in fig.5 shows notices received by the clients.
5. CONLUSION
In designing of this project we came to know that there is a
digitized way to use of notice board by using Raspberry Pi
without internet. Thus raspberry-pi being a small yet
powerful device can work efficiently on a digital notice board
connected with Wi-Fi and software. Hence Apache Web server
can provide users with data which can be shared over
browser application within Wi-Fi range.

Fig. 1 Show the block diagram of the system. The notice to be displayed is send as a file (PDF, DOC, etc.) the message transferred via WI-FI(offline) on any smart phone.Since WI-FI network is being used the notice can be send practically in Wi-Fi network .The notice is received by any smart phone and it is store in internal memory. This is accomplished by the means of establishing FTP between Raspberry-pi and smart phone.By creating access point in raspberry pi it gives connectivity between server and client that is raspberry pi and smart phone respectively. Fig.2. Top View of Raspberry-Pi The Raspberry-Pi has two video output options composite (Radio Corporation of America - RCA) and High-Definition Multimedia Interface (HDMI). Display screens with VGA port can also be used by using HDMI OUT of the Raspberry pi with an HDMI to Video Graphics Array (VGA) convertor. Therefore, the proposed method is versatile with respect to display options. The operating system used in Raspberry-Pi is Raspbian. The most popular programming language for Raspberry Pi is Python. It is a high-level language and thus lesser coding effort is needed as compared to using assembly language for other microcontroller boards. Thus, the method proposed in this paper has several advantages over the prevalent methods used to offer the same functionality. 4. IMPLEMENTATION Fig.3. Implementation flow chart This section explains the execution flow from establishing an Access Point and installing Apache server to communicate between the Server and Clients i.e. Raspberry pi to displaying the notices on the screen of Smart Phones. After successfully installing Apache HTTP server then a folder will automatically generate named as ‘www’, in that folder a HTML page is present. But as we need any type of file format to display, by command-line-terminal, remove HTML page and by passing PHP script it will allow adding and removing folders and notices at server site. Notices in any type of format such as doc, pdf, excel, JPG, etc. is stored in a folder named ‘www’ and is ready to access for clients within wifi range.
