ACKNOWLEDGEMENT
I wish to express my immense gratitude to God Almighty for his mercy, guidance and protection towards me for seeing me through the rigors of this work. I am greatly indebted to my supervisor Engr. Ejimofor for his kind gesture and whose critics lead to the achievement of this work. I also will remain grateful to the tremendous contribution of my lecturers Engr. Ojobor (the Dean of Engineering Faculty), Engr. Ejimofor (Head of Electrical Electronic Engineering Department), Engr. Mbah, Engr. Ochi, and all the staff of Electrical Electronic Engineering both academic and non academic staff for their intellectual upbringing. My special appreciation goes to my loving parents Engr. & Mrs. Chukwu A. Orioha, my grandparent, my uncles and aunties, my brothers and sisters whose moral and financial support cannot be over emphasized. Also my sincere gratitude and special regards to my friends too many to mention whose encouragement also lead to the success of this work.
Today notice board has become an important thing in institutes/organization or public places like railway stations, bus stands and hospitals. But to use the paper notices sticked on a notice board is a time taking and expensive process and there is wastage lot of time, paper and labour. The Notice board is used to display the information in an effective way to the people, but to update the messages instantly is not easy on the notice board. In this project deals about an advanced Hi-Tech wireless Notice Board. This system is enhanced to display the latest information through an Android application of smart phones or tablet.
CHAPTER ONE
1.0 INTRODUCTION
Main concept behind Voice operated Electronic notice board using display is to show messages and to control them by using our own voice. We have already seen GSM based Electronic Notice board, however speech controlled Notice board has additional advantage of ease of use. User has to give voice command in his/her own voice to control the messages displayed on electronic notice board. Voice recognition is done in the Android application. User has to install this Android application in his/her smart phone or tablet.
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.
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products.
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is design an innovative android based notice display system that allows the user to display notices without typing them in manually.
1.3 PURPOSE OF THE PROJECT
The purpose of this work is to provide an efficient way to the user for displaying notice.
1.4 SCOPE OF THE PROJECT
So here we propose an innovative android based notice display system that allows the user to display notices without typing them in 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 an LCD screen to display messages. The LCD is interfaced with an 8051 family microcontroller. We also use a Bluetooth receiver to get the android transmitted messages, decode them and send them to the microcontroller for further processing. The microcontroller then displays the message on the LCD screen. The entire circuit is powered by a 12 V supply through a transformer.
1.5 APPLICATION OF THE PROJECT
This innovative system can be used in a variety of places including:
- railway
- stations,
- schools,
- colleges,
- offices ,
For displaying emergency announcements on the screen instantly by just speaking out the message instead of typing it in each time. So this is how voice based notice board project is very useful in various organizations.
