Abstract

The Voice Controlled Notice Board is a computer controlled machine. This automated system can reduce the manual work. The construction of a simple and low-cost Voice Controlled Notice Board is addressed in this framework. The aim of this device is to create an automatic display board that is controlled by the Internet. This electronic machine is made up of both software and hardware components. The key goal of this device is to provide a remote notice board that faculty can use to post the most recent notices and announcements. The other goal is to improve contact speed while still saving time and money. It may also be used to increase the re - usability of existing designs and reduce the amount of space available, lowering costs.Wi-Fi-based cellular serial data networking is used in the proposed system. For Wi-Fi connectivity between an Android-based personal digital assistant and a remote wireless display screen, Android-based device applications are used. In this design, messages are sent through an Internet from an authorized transmitter and then message is transmitted to the Node MCU and the message is read and sent to digital display board.

Highlights

In our day-to-day life we would have come across work and time
Bluetooth or Wi-Fi-based wireless serial data communication has been used in their proposed framework
Android-based software applications for Bluetooth and Wi-Fi communication between Android-based personal digital assistant devices and the remote wireless display board are used for this purpose.S

Summary

Introduction

In our day-to-day life we would have come across work and time. The concept of this system is to design an Internet driven automatic display board. Many notice boards that is been displayed on It is proposed to design receiver cum display board schools/colleges and public places like Bus which should be programmed from an authorized stations, Railways, Malls and Airports etc and mobile phone. In this system, a voice-based realized in what way notice board is a messageis sent through an Internet from an primegadget. In the power supply unit, there are four units that transformer of 14 volts,as thepeak voltage is Vp =. Convert the AC power supply to DC power supply. 1.41 x 14 =19.74volts

They are Bridge Rectifier Circuit
