[Audio] User-Friendly Interfaces: M-I-T App Inventor and similar tools enable management of messages and their display so as to enhance arrangement of messages in public. Environmental Benefits: Moving away from paper to digital notices minimizes waste as well as supports the reduction of paper used in society. They show applies the possibilities of developing technologies and unexpected ways of their application in nano-devices. research A-N-D methodology To ensure the success of our project, thorough research is essential. We discuss the methodologies used in designing and developing Electronic Notice board. This includes requirements analysis, design and prototyping, software development, integration and testing, and deployment and maintenance. By following a systematic approach, we can create a well-functioning Electronic Notice board. It involves a series of steps and processes aimed at achieving the desired functionality and performance of the board. 1. Agile Development: Iterative and incremental approach, emphasising flexibility and rapid delivery. 2. Waterfall Methodology: Linear and sequential approach. Muchemphasised proper planning and documentation are done. 3. Scrum Framework:Approach using collaboration in iterative manner conducted through sprints and stand-ups every day. 4. _Kanban Methodology:It is a visual approach with much flexibility around continuous improvement and delivery. 5. Rapid Prototyping: Iterative and experimental approach that emphasises fast testing and refinement. 6. User-entered Design (U-C-D--): Human-entered approach; it places a great emphasis on user needs and experiences..

[Audio] 7. Test-Driven Development-TDD: A development approach that is highly focused on automated testing and validation. 8. Extreme Programming-XP: An iterative-incremental software development method that focuses greatly on technical excellence and teamwork. 9. Lean Software Development: This efficient, waste-reducing approach is highly engaged with continuous improvement. 10. Hybrid Methodology:The combination of elements from multiple methodologies that can provide a better fit for the unique demands of a project. These methodologies can be applied to different aspects of the development of the Electronics Notice Board, such as but not limited to: a) Hardware design and development b) Software development and integration c) User interface and user experience design d) Testing and quality assurance e) Deployment and maintenance Thus, the selection of an appropriate methodology or combination of methodologies ensures the successful and effective implementation of the Electronics Notice Board. Simulation software The electronic notice boards with E-S-P-3-2 and dot matrix displays often provide an enabling environment through the use of different components and libraries. 1. Communicational functionality with max7219: In most cases, the max7319 module serves the purpose of driving L-E-D dot matrix displays connected to ESP32. Thus, an accumulated message in the dot matrix can be built using the libraries . 2. Mobile Applications: The applications created from M-I-T App Inventor also allow sending messages to E-S-P-3-2 over Wi-Fi where the messages are then appropriated on the dot matrix..

[Audio] 3. Web Interface: Other works implemented a web based system through which the users could send messages which the E-S-P-3-2 would display on the matrix. Collectively, these features aim at improving both the usefulness and the interaction experience of electronic notice boards with end users. Conclusion In this project, an ESP32-C6 WiFi Module can be interfaced with an 8-in-1 max7219 Dot Matrix L-E-D Display. ESP32-C6 connects to WiFi network and creates web page. It is possible to view the webpage through the local IP address of the ESP32-C6. Any message can be sent and displayed using the Dot Matrix L-E-D Display with the help of the Web Dashboard..
