Abstract—This project looks at a cool & innovative way to show messages on an electronic display board using wireless tech. Notice boards are a must-have in any organization or public places like hospitals, airports, bus stations, railway stations, shopping malls, & parks. Writing down different notices by hand can take a lot of time and is quite boring. To fix this problem, we come up with the idea of a wireless digital display board here.
The main goal of this project is to create a notice board that can get & show messages from a trusted user from anywhere around the globe using IOT and also GSM technology. The development of IoT-based projects facilitates rapid data transformation and remote accessibility, enabling users to access information from anywhere globally. A cloud-connected display continuously monitors for user messages, automatically updating the TFT display upon receiving data uploads through the server. Utilizing the System Wi-Fi, users can upload messages to the TFT display by accessing a server-connected website from anywhere in the world. This setup reduces update timeframes and efficiently transfers data to end-users, enhancing overall information dissemination.
In scenarios where internet connectivity is unavailable, GSM technology provides an alternative solution for data transmission. By integrating a SIM card into the GSM module connected to the wireless display board, authorized users with mobile phones can send messages that are received and displayed on the notice board. This setup enables seamless communication and efficient information dissemination. With GSM technology, trusted users can send messages from anywhere globally to be displayed on the notice board, ensuring timely and reliable communication.
