Android Controlled Notice Board Project
Project Idea
An electronic notice board controlled by an Android device via Bluetooth. It eliminates the need for physically updating notices daily by receiving messages wirelessly from the Android app, then displaying them on an LCD using an 8051 microcontroller.
 
Project Description
This project uses an 8051 microcontroller interfaced with a Bluetooth module and a 16x2 LCD to display real-time messages sent from an Android device. The Bluetooth module receives messages transmitted from the Android app, which are processed by the microcontroller and shown on the LCD screen. This improves information dissemination in places like colleges, offices, railway stations, and airports, making notice updates effortless and maintenance-free.
