Voice Controlled Notice Board through IOT

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.
