Notice board is the most consistent and main appliances in every university, school, or public place location such as bus stations, train stations, parks. But fixing and updating specific instructions on every day is a difficult operation. Wireless electronic notice boards are a faster alternative to conventional pin-up type notice boards. The main goal of this project is to design a wireless notice board to displays notifications that are received from a smartphone user. In this paper, the development of a simple and low-cost Android-based wireless notice board is presented. A prism-shaped device, having a portable circuit inside and an LCD outside is a solution for displaying any messages or notices immediately. A user can type a message in the app and the message will be displayed on the notice board instantly. It is a convenient substitute for a traditional noticeboard where written papers are pinned on the board. Other than institutional purposes, the same technology can be used in traffic signals, railway stations, bus stands, shopping malls, and in every public place where people can get messages or emergency alerts. The wireless notice board display is configured using NodeMCU, 16 × 02 LCD Display, I2C Adapter for 16 × 02 LCD Display, Buzzer, Mini Breadboard, Jumper Wires, and PVC Boards. As the electronic notice board is wireless so it minimizes the hassles of wires as well as it is very easy to operate and consumes less power.
