Smartphone Controlled Wireless Notice Board Using Ardunio UNO

Computer Science and Engineering

The proposed system uses an electronic notice board that can show messages and is managed by a Smartphone device. Information displays are quickly moving toward digital technology these days. This would enable us to transmit messages nearly instantly and without delay just by sending an SMS, which is more dependable and superior than the outdated, customary method of posting messages on the bulletin board. This suggested technology may be utilized to improve security, increase emergency situation awareness, and prevent numerous risks at institutions, public spaces, malls, and large structures. Show the message on the display board using the Bluetooth module. This paper's primary goal is to create a wireless notice board that shows user-sent messages. The notice board is the most important feature of any establishment, whether it be a public park, railroad station, or bus stop. The field of communication technology has advanced rapidly during the past few decades. Its significance in disseminating knowledge about anything from domestic issues to global occurrences has already been shown. In this study, we describe the creation of an automatically and remotely updated e-notice board that is managed via SMS. An LCD display and a Microcontroller were used to operate a Bluetooth module integrated circuit (IC) in the system.
