Wireless electronics notice boards are a faster alternative to other notice boards (GSM based and low range communicating systems.The proposed system uses Bluetooth and Wi-Fi based wireless serial data communication using programmed (esp32 devkit v1) microcontroller for transmitting user data.At receiver end a low cost microcontroller board (ATMega328P) is programmed to receive and display any above information from the transmitting side (through user). A major constraint of this method used so far is of small size display board. We use advanced larger display board with low power consumption with reduced data transmission time from sender /user to the receiver end display. The developed system will therefore aim in wirelessly sharing the information through Bluetooth and displaying in a notice board.

Whether it’s through the internet or television, people want to be informed and up-to-date with the latest events happening around the world (J. S. Lee 2007). Wired network connection such as Ethernet has many limitations depending on the need and type of connection. Now a day’s people prefer wireless connection because they can interact with people easily and it require less time. The main objective of this project is to develop a wireless notice board that display message sent from the user and to design a simple, easy to install, user friendly system, which can receive and display notice in a particular manner with respect to date and time which will help the user to easily keep the track of notice board every day and each time he uses the system. Wi-Fi is the wireless technology used and also using a Bluetooth technology. This Document gives basic introduction to Digital signage which can operate using Wi-Fi and Bluetooth. Now a day we have very less option for advertising and it is very lengthy and boring process to advertise and also we have very less efficiency of that. So we have one good option to reach over a people is Digital signage system. Recently we have a digital signage but we have to change its content using USB drives or using internet when we are in the local or in wide area network. So this document gives us better idea how to change the contents of Digital display using Wi-Fi and Bluetooth. So for that we use some Embedded as well as communication idea and using ESP32devkit v1 board and HC-12 Bluetooth module we try to implement our system. The OLED used as to 16-bit level the information are to be displayed.it specifies the characters and to display it whenever type to show the text in to the user language. All major urban areas are currently covered by both WI-FI network providers, and soon every single corner of the peoples has used in mobiles in a very poor villages to call away. The method to need for constant communication with family and friends, coupled with the relatively cheap method of sending short text messages to them, has information a WI-FI revolution in the country. In fact, rarely will a used this method use his cell phone to make a phone call, Preferring to anything and everything. All mobile phones has available in WI-FI network. Then WI- FI network has been used to provide wide area network allows as to communicate with the information into text message through OLED display to move the notice board. Information can passing through for a specific service provide as chatting and to transmit and receive the information.
