Bulletin board is the primary thing in any utility institution / organization or public places such as bus stations, railway stations and parks. However, pasting up multiple day-to-day ads is a difficult process. A separate person is required to care for this notice screen. This project is about an advanced high-tech wireless bulletin board. The main goal of the project is to develop a wireless bulletin board that displays messages when a message is sent from the user's Android application device. Remote operation is achieved by any Smartphone / Tablet, etc., with Android OS, through a graphical user interface (GUI) based on touch screen operation. While the user sends the message from the Android application device, it is received and retrieved by the Bluetooth device on the display unit. The Bluetooth access password will only be known by the user. It is then sent to the microcontroller which further shows the notification sent by the user to the electronic bulletin board which is equipped with a 16X2 LCD screen. It uses a microcontroller of the family 8051.


The power supply consists of a 230 / 12V lowering transformer, which lowers the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The undulations are removed using a capacitive filter and then regulated to +5 V using a 7805 voltage regulator which is required for the operation of the microcontroller and other components. This circular system of embedded messages puts into play a microcontroller 89S51. This is an extremely flexible and cost-effective solution. The power supply is used to provide a regular power of 5V to several ICs in the embedded circular message circuit. An encoder is used which is a transducer to translate data from the given format to the required format, this is done only to save and accelerate the processes. This circular embedded message system mainly contains a microcontroller, a RF MODULE, an encoder, a power supply unit, a decoder and an LCD display. The use of this wireless system incorporated in this assignment as a substitute of common purpose computers has the benefit of performing a narrow series of works. This translates into a decrease in overhead costs and complications. The decoder used in this system is only contrast with the encoder used to collect the original information.
