Objectives
- Understand the problem statement and define clear functional requirements for the system.
- Structure the application into clean, reusable modules with proper data handling and validation.
- Design and implement the complete solution using Java, MySQL, Spring Boot, Bootstrap.
- Test the implementation, document the results, and prepare a working demonstration.

Software and Tools
- Arduino IDE

Technology Stack
Java, MySQL, Spring Boot, Bootstrap, jQuery, HTML, CSS

Working Principle and Implementation
The application follows a modular structure: a user-facing interface collects input, the core logic processes the data and applies the required rules, and the results are stored or presented back to the user. Data is managed through MySQL. The project is organised so that each module can be developed, tested and extended independently.

Applications
- Academic mini/major project submission for B.Tech and Diploma (Java).
- Base platform that can be extended with additional features for real-world use.
- Hands-on practice with Java, MySQL, Spring Boot.

Learning Outcomes
- Practical understanding of Java, MySQL, Spring Boot.
- End-to-end project workflow: requirement analysis, design, implementation and testing.
- Documentation and presentation of a complete engineering project.
