voice notice board

Project Area of Specialization Software EngineeringProject Summary

We come across situations where we need to urgently need to display notices on a screen. For areas like railway stations and other such busy facilities the station master/announcer need not have to type in every announcement message manually on the screen. So here we propose an innovative android based notice display system that allows the user to display notices without typing them in manually. The main concept behind Voice operated Electronic notice board using a rolling display is to show scrolling messages and to control them by using our own voice. however, speech controlled Notice board has an additional advantage of the ease of use. The user has to give voice command in his/her own voice to control the scrolling messages displayed on the electronic notice board.

Voice recognition is done in the Android application. The user has to install this Android application on his/her smartphone or tablet. Then the user has to give voice commands to this android app. The android app then passes these commands to the microcontroller using wireless communication. It means the user doesn’t have to go near the Electronic notice board to change the scrolling message. The wireless communication technique used in this project is Bluetooth technology. Messages to be displayed are stored in Electrically Erasable Programmable Read-Only Memory. EEPROM memory holds data even after the circuit is reset. The microcontroller receives these commands with the help of Bluetooth receiver and decoder. Then it passes these commands to the Rolling display which is made up of Matrix LEDs.

The era of mobile technology opens the windows to the android app. The websites are disappearing and the mobile phones are prominent.It’s the time to change from conventional websites and other things to apps, which has become the part of our daily routine. we are introducing “VoiceNoticeboard.apk” the android application software which would convert the voice to text. It works on all android platforms. Our multipurpose program is considering the user as an Albertan or nonAlbertan, student or parent, faculties or office staffs individually. Project gives a total solution to everyone. It gives us more comfort and a better user interface later on Students can interact with Google directly. Latest news and updates is got through the application.

Project Objectives

The main objective of the project is to develop a wireless notice board that displays notices when a voice message is sent from the users mobile using an android app. While the user sends the message from the mobile, the remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based voice operation. Bluetooth wireless technology is a popular technique in the communication arena, and it is one of the fastest growing fields in the wireless technologies. Bluetooth technology handles the wireless part of the communication channel; it is used in this project to transmit and receive data wirelessly between devices. While a phone is simply more than a phone these days, it is a smartphone the number of applications being built on a wide range of platforms for smart phone is astounding. Transmitting end uses an Android application device remote through which commands are transmitted. At the receiver end, these commands are converted to texts used which are displayed on a LED Display interfaced to the Arduino. Serial communication data sent from the Android application is received by a Bluetooth receiver interfaced to the Arduino.

Project Implementation Method

Wireless communication technique used in this project is Bluetooth technology. Voice recognition is done in the Android application. User has to install this Android application in his/her smart phone or tablet. Then user has to give voice commands to this android app. Android app then passes these commands to the microcontroller using wireless communication. It means user doesn’t have to go near the Electronic notice board to change the scrolling message.Then it passes these commands to the Rolling display which is made up of Matrix LEDs.

Benefits of the Project

We come across situations where we need to urgently need to display notices on a screen. For areas like railway stations and other such busy facilities the station master/announcer need not have to type in every announcement message manually on the screen. So here we offer an innovative Android based notice display system which allows the user to display the notice without typing manually. Here the announcer/administrator may speak out the message through his/her android phone, the message is then transferred wirelessly and displayed on the screen. To demonstrate this concept we here use an LCD screen to display messages. The LCD is interfaced with an 8051 family microcontroller. We use a Bluetooth receiver to receive Android-transmitted messages, send them to the microcontroller for decode and further into the process. The microcontroller then displays the message on the LCD screen. Use of this notice board system can be used in various places including railway stations, schools, colleges, offices to display emergency announcements on screen instantly, instead of typing the message at all times. So that voice based notice board project is very useful in different organizations.

Technical Details of Final Deliverable

1. Android application to detect voice commands: Android app on smartphone or tablet will be used for speech recognition.
2. Bluetooth receiver and decoder: This device is used to interact with the Android application.
3. Microcontroller: We have used an 89s51 microcontroller which is an 8051 series microcontroller. It interacts with Bluetooth receiver, LCD display, rolling display. In short, it is the heart of the system.
4. Rolling Display: This is the main display unit, which shows various scrolling messages.
5. LCD display: It shows various messages. It is an optional device in this project and is just used for testing purposes.
6. EEPROM: E2PROM memory is used to store the message. EEPROM holds the data even after power failure. An I2C communication protocol is used for interfacing 8051 with EEPROM.
