Abstract - Now a days the advertisements are digital. Notice boards are widely used ones ranging from
primary schools to bus or railway stations to convey messages at large. In schools and colleges notices
are displayed on paper. So this is very hectic process to write a notice on paper then take permissions
and signatures from faculties and HODs. To reduce the waste of paper and time we have developed the
Real Time Notice Display System which displays notice on the board by using raspberry pi with cost
effective method and in a convenient way to display notice. One of most obvious reason is the drastic
effect of LED display to capture attention. Which gives good impression in front of people and crowd.
Applications are developed having a feature called real time update. These applications include
domestic devices such as TV, smart phones etc., so why not smart boards.
So this project is developed with Raspberry pi 3. The Raspberry pi provides all the functionality to
display notices. Real Time Notice Display System using Cloud is a task of displaying notice on the notice
board using Raspberry pi which will be sent only by authorized user through cloud. The notice board is
a user friendly system which can receive and display notice in a particular order with respect to date
and time which will help the authorized user to easily keep the track of notices on the board each time
when user uses the system. It provides user a simple, fast and reliable
way to put important notices on LCD Display.
Index Terms – Raspberry Pi, LCD Display, Web Server, Electronic Components.
I. Introduction
This project provides ease of communication between administration and students in colleges. Whenever a
notice is passed, it can be directly displayed on the Digital notice board, without efforts like printing on a paper
and then attaching it manually to the notice board. Many of the students don’t have a habit of continuously
check and read the notice board. But using digital notice board we can directly display it on a big LCD display
board, which can be easily read by many students at a time. Hence most of the students can quickly come to
know what is the notice and the important message is conveyed to all. The notice keeps on rolling over and
over. Keeping these importance of display system we are presenting our paper to help in improving the
communication between administration and students.
This has been implemented on LCD (Liquid Crystal Display). The URL which will be used by users has been
hosted on a web server and a raspberry pi use to display text on display device. The entire system is modular
with scalable and secure authentication levels, real time syncing of notices and an omnipresent cloud support.
Practically, all resolutions are supported. The font size is customizable and it can display written documents as
well as images at the same time.
The main aim of our project is to eliminate the use of paper in many organizations and institutions by replacing
paper with LCD display.

II. Literature survey
Ashmita, Aarthy, Aditi, Dr. R. Ranihemalini Abhineyaa, 2017 proposed a Digital Notice Board Implementation
via power line communication. Power Line Communication (PLC) provides high speed communication of voice
and data. Power Line Communication uses lines for transmitting data. When a message is received, it is
initiated using voice board.[1]
Dhara G. Rangani, Nikunj Tahitramani, 2017 proposed a Smart Notice Board System. Here MQTT protocol and
Arduino is used. MQTT is a light weight client server message exchange protocol. MQTT is even lighter than
HTTPs protocol. Message sent from from an android phone or web interface goes to MQTT broker. ESP8266
will be connected to MQTT broker to receive an messages that MQTT receives. And then eventually a process
will take place to display message on LED screen. [2]
Neeraj, Divya, Sambhavi Awasthi, 2016 proposed a Development of simple and low cost Android Based
Wireless Notice Board. Bluetooth or Wifi based communication is done by the android users.Transceiver
module with the microcontroller Bluetooth or wifi for data communication.[3]
Yash, Radhika, G. Shiva Shridhar, 2015 proposed a Large Screen Wireless Notice Display System. It uses only
HTML script and uses Raspberry pi. SMS is received by GSM modem and stored in Subscriber Identity Module
(SIM). Only few text messages is been displayed in LED.This HTML output can be displayed by web browser
running on the Raspberry Pi.[4]
Dharmendra, Vineeth, Krishnan, B.A. Botre, S.A. Akbar, 2015 proposed a Small and medium range wireless
electronic notice board using Bluetooth and Zigbee. Common compatibility receiver hardware for notice board
having compatibility with both wireless modules (Bluetooth and Zigbee). Zigbee can transmit or receive data
using a terminal software. It uses for data transmission range test.[5]
III. Methodology
The architecture of the system is as shown –
Fig : System Architecture.

Figure describes the proposed architecture. The ultimate goal of the system is to develop a wireless notice
board that displays notices in the form of text and images as per the need. It uses a Raspberry pi as a processor.
Raspberry pi is equipped with a Portable LCD display. We can display messages and can be easily set or
changed from anywhere in the world. For that we will buy server and upload a script to insert data which we
will access through URL. Using that URL we enter message then system will sent this message to cloud. Then it
passes to the notice board which is connected to raspberry pi and then displayed on the screen. System consist
of two section called as sender and receiver. Sender is responsible for sending valuable information through
the wireless network. In order to access notice board the sender must enter into the corresponding web
address. For preventing unauthorized access to web address we provide security authentications like
username and password. If the username and password entered are invalid then the user can’t access the
notice board. When the user enter correct password and user name web address will opened and get space for
the Information transmission. User can access this web address using personal computer. To make the
proposed system more user friendly we have created URL. By using this URL sender can directly enter these
messages includes text file will send to the server. And here we have used 000webhost server for hosting the
website.
In the simplest terms, server means storing and accessing data and programs over the Internet instead of our
computer's hard drive. Raspberry pi is connected on Wi-Fi for accessing internet. Raspberry pi is a capable
little device that enables people of all ages to explore computing, and to learn how to program in languages like
Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and
playing high-definition video, to making spreadsheets, word processing. Raspberry pi is activated by supply
power around 5v. After switch on Raspberry pi, it will collect data from the cloud. The web address for
collecting data from the cloud is already specified through program written in the processor. Upon receiving
messages it will displayed on the monitor. Raspberry pi has no VGA port. So in order to interface LCD monitor
with Raspberry pi, HDMI interface is used. The received text messages are displayed on the screen like scrolling
manner. Python code is used to creating the panel on which the notice will be display. Similarly received images
will display on the screen. To achieve this, monitor screen is splitted into two sections. Each section displays
each page. By certain delay notices are scroll up and down for fixed time interval.
1. System Requirements :
Softwares : Raspbian OS , Apache Server, MySql
Hardwares : Raspberry Pi 3 , SD Card , HDMI to VGA connector , LCD Monitor.
Languages : HTML , PHP , JavaScript.
2. Stepwise procedure to display notice:
1. User need to sign up first
2. Log in with the correct credentials

3. Enter the notice and attach image
4. All data store in the database
5. Raspberry pi fetches the notices from web server
6. Display into the monitor screen/ LCD screen
3. Description of raspberry pi configuration with the monitor screen:
Monitor display is connected to Raspberry pi. The kiosk script is used to handle the bulk of the work for
raspberry pi kiosk, including launching Chromium itself.
@xset s noblank
@xset s off
@xset -dpms
These commands are important as they help to stop the Raspberry pi’s display power management system
from kicking and blanking out of screen. These three commands set the current lxsession not to blank out the

screensaver and disables the screensaver altogether. The third command disables the dpms that make desktop
interface should never blank out the screen
sudo nano/etc/xdg/lxsession/LXDEpi/autostart
To enforced desktop auto login and written kiosk script, need to go ahead and modify the lxsession autostart
script by running above command on the raspberry pi.
@chromium-browser - -kiosk
http://bvcoenotice.000webhostapp.com
This flag sets Chromium to operate in Kiosk mode, this locks it into a particular set of features and only allows
limited access to both the web browser and any other OS functionality. Chromium’s kiosk functionality takes
full control of the screen, maximizing Chromium to the full size of your screen and stops user input from being
accepted by the OS.
http://bvcoenotice.000webhostapp.com
This could be the web page that the script will open when power on display monitor.
IV. Conclusion
Thus we have successfully designed a simple, user friendly system which can receive and display notice in a
particular order with respect to date and time which will help the authorized user to easily keep the track of
the notice board whenever authorized user uses the system. Thus it savs time and resources and making the
information available instantly to the intended person. Thus we have achieved the aim of this project of
digitizing the existing conventional bulletin notice board with a much more efficient and versatile digital one.
This system can be used in various applications like banking, schools, restaurants, offices, hospitals etc.
