DESIGN AND DEVELOPMENT OF AN ESP32-BASED SMART NOTICE BOARD

The developed Smart Notice Board was implemented and tested to evaluate its performance in terms of real-time notification delivery, display response, reliability, and ease of use. The system successfully displayed the notices received from the authorized user without requiring manual replacement of printed notices. This made the overall process of updating information faster and more convenient compared with the conventional notice board system. During testing, different types of messages such as academic announcements, examination updates, event information, and general notifications were transmitted to the notice board. The messages were received and displayed correctly, demonstrating that the proposed system can be used for regular institutional communication. The system also allowed notices to be updated remotely, reducing the need for staff or students to physically visit the notice board whenever a new announcement had to be displayed. The response of the system was found to be satisfactory for normal usage. Once a notice was submitted through the user interface, it was transferred through the communication network and displayed on the digital board with minimal delay. The display remained clear and readable, allowing students and staff to easily view the information. The system also reduced the use of paper and the manual effort involved in printing, collecting, and replacing notices. Another important observation was the convenience provided to the administrator. Since the notice can be modified or updated digitally, incorrect or outdated information can be replaced quickly. This improves the reliability of communication and helps ensure that the latest information is available to users. The proposed approach is therefore suitable for educational institutions where announcements are frequently changed or updated. Overall, the experimental results indicate that the Smart Notice Board provides a simple, efficient, and practical method for digital information sharing. The system reduces manual work, improves the speed of communication, and provides a more flexible alternative to conventional paper-based notice boards. With further improvements such as notification alerts, scheduled announcements, mobile access, and enhanced security, the system can be extended for wider smart-campus applications.
