To develop an interactive traffic signal simulation using React.js, which visually represents the behavior of a traffic light system with changing signals (red, yellow, and green). The goal is to demonstrate state management, component rendering, and timing functionalities in React.

???? Core Features:

1. Traffic Signal Components:

• The traffic signal is represented as a set of React components (e.g., TrafficLight, Signal, Button, etc.).
• Each signal (Red, Yellow, Green) is displayed as a colored circle or light.
• Components will dynamically change color based on the current signal.

2. Signal Cycling:

• The traffic light cycles through the following states:
• Red -> Green -> Yellow -> Red (repeat)
• This cycle is controlled by setInterval or setTimeout in JavaScript, and React updates the state accordingly.

3. Manual Control (Optional):

• Users can manually control the signal (e.g., switch to red, green, or yellow using buttons).
• This can be implemented using React state to change the color of the signal based on button clicks.

4. State Management:

• React's state is used to manage the current signal (e.g., red, yellow, green).
• The state is updated at specific time intervals, simulating the timing of real traffic signals.

5. Timer Display (Optional):

• Display a countdown for each signal color (e.g., 30 seconds for green, 5 seconds for yellow).
• This can be implemented by adding a timer state that decreases every second until the signal switches.

????️ Technology Stack:

• React.js – for building components and handling state management
• JavaScript – for handling the timing logic (signal switching, countdown timer)
• CSS/Styled Components – for styling the traffic light components and the page layout
• Hooks (useState, useEffect) – to manage signal states and timing

✅ Project Outcome:

• A fully functional traffic signal simulator with:
• Automatic cycling between red, green, and yellow signals
• Optional manual control to change the signal
• Optional countdown timer for each signal
• Demonstrates:
• React component structure
• State management using useState and useEffect
• Event handling and timing logic
