This system reduces the usage of paper by replacing the conventional notice board into a digital notice board. The user can send notices either by SMS or Web application to the GSM and it the display the notice in LCD monitor. And the displayed notices get forwarded to authorized user's mobile number through GSM. Authentication is achieved through password. Raspberry Pi 3 controls the overall process. Through this system the user can send the notices from anywhere with in a fraction of second.

4. ABSTRACT
 This project aims to reduce the paper usage in the name of sticking notices in
conventional notice board.
 LCD display is used as an electronic notice board for displaying message sent
through SMS or by WEB APPLICATION.
 For secured usage of notice board, the password should get matched with the
predefined password.
 First, the user has to send the message to GSM module which will get displayed
on the LCD.
 Then the raspberry pi will send the displayed message to some mobile numbers
which were already stored.
 In web application images can also be sent.

5. INTRODUCTION
 Notice Board is a primary thing in any institution/organization or
public utility places.
 Sticking various notices day-to-day is a difficult process. A separate
person is required to take care of this notices display.
 A permanent solution for these difficulties is wireless access to the
Notice board, with a user friendly system.
 Hence, this project is built around raspberry pi which provides all
the functionality of the display and wireless control.

7. DISADVANTAGES OF EXISTING SYSTEM
 Coverage area of Bluetooth or zigbee is small.
 So the user want to be in a particular limit.
 Difficult to send text through Bluetooth.
 Unauthorized users can also able to send the message.

10. Why Raspberry pi?
 Raspberry pi 3 model consist of 64-bit quad-core ARM Cortex-A53 processor.
 Open source technology.
 It is having HDMI male cable connection option so LCD monitors can easily get
connected.
 It has in built wi-fi and Bluetooth module, which will support future
advancement.
 Program memory(RAM) size is 512MB.
 Processor speed ranges from 700 MHz to 1.2 GHz.
 It is having additional SDcard (secure digital card).

12. AUTHENTICATION
 To display the required notice in raspberry pi connected LCD
display the user has to send the notice or message along with the
password.
 The password has been already programmed to Raspberry pi if the
password matches, then the notice will get displayed.
 Otherwise, it will discard the notice.
 If we are sending notices via internet then the user have to log in to
the web application by using user id and password.

13. Advantages of GSM
 Using GSM mobile we can send message to any distant locations,
from any part of the World.
 GSM wireless transmission system it has very less errors and needs
less maintenance.
 It offers higher security to the transmitting data.
 Notifications can be delivered within second.

14. WEB APPLICATION
 We are using a web application named projectone.in/noticedisplay/
 The web application has been designed by using PHP.
 The displayed message/notice get stored in the web application.
 The notices can also get deleted through the web application.
 Notice can be a message as well as image can get displayed using
this web application.

 No printing and photocopying costs.
 Thus saves time, energy and finally environment.
 Multiple Users are authorized to update notices on the electronic
notice board.
 Prevents unauthorized access of notice board.
 Problem related to direct manual update of notice board is removed.
Just an SMS is enough.
