There are certain circumstances encountered occasionally where a notice is needed to be urgently displayed on a screen. The station master or announcer does not need to manually type each announcement message onto the screen in busy facilities like railway stations. Therefore, the user here suggests a creative android-based notice display system that enables users to display notices Without manually entering them in. Here, the announcer or administrator can read out the message using an Android phone; it is then wirelessly transmitted and shown on the screen. Here, messages are displayed on an LCD screen to illustrate the concept. A microcontroller from the ATMEGA328P family is connected to the LCD. Additionally, the user uses a Bluetooth receiver to receive the messages that the android transmits, decode them, and then pass them to the microcontroller for additional processing. The message is then shown on the LCD screen by the microcontroller. Through the use of a transformer, a 12 V supply powers the complete circuit. This cutting-edge technique can be utilised in many locations, such as train stations, schools, universities, and offices, to immediately show emergency announcements on screens by voicing out the message rather than typing it in each time. As a result, voice-based notice board projects are quite helpful in a variety of organizations.
