Introduction
Traditional notice boards are slow, costly, and require manual updates.
Problem: Lack of real-time, wireless, sustainable solutions.
Aim: Replace conventional notice boards with a GSM-based wireless display system.
Objectives:
Develop prototype using Arduino + GSM modem + LCD/LED display.
Implement SMS-based notice display.
Ensure security with authorized numbers.
Test performance in real-world scenarios.
