Key Concepts
- State management to handle time and button controls.
- Using React effects for timing events.
- Implementing UI updates without page reloads.
- Applying Tailwind CSS for styling and layout.
Learning Objectives
After completing this project, students will be able to:
- Use the useState and useEffect hooks to manage dynamic behavior and timing.
- Design simple yet functional user interfaces.
- Implement basic control logic for interactive components.
- Enhance UI using a CSS utility framework.
