🚦 Traffic Light Signal Simulator (Python + Tkinter)

A simple GUI-based Traffic Light Simulation built using Python and Tkinter. This project visually represents real-world traffic signals with a countdown timer for each light (Green, Yellow, Red).

📌 Features

• 🚦 Realistic Traffic Light Simulation
• ⏳ Countdown Timer for each signal
• 🖼️ Image-based light display (Green, Yellow, Red)
• 🔄 Continuous automatic cycling
• 🧠 Event-driven programming using Tkinter (after())

---

🛠️ Tech Stack

• Python
• Tkinter (for GUI)
• Pillow (PIL) (for image handling)

---

🚀 How to Run

1. Clone the repository

https://github.com/ashishkumardata/Traffic-Light-using-Python-While-Loop-.git

2. Install dependencies

pip install pillow

3. Run the program

python main.py

🖼️ Requirements

Make sure these image files are present in the same directory:

• green.png
• yellow.png
• red.png

⚙️ How It Works

• The program cycles through traffic light states:

  • 🟢 Green (15 seconds)
  • 🟡 Yellow (5 seconds)
  • 🔴 Red (15 seconds)
  • 🟡 Yellow (5 seconds)

• Uses Tkinter’s after() method for smooth, non-blocking updates.

• Updates GUI every second with a countdown timer.

🔧 Future Improvements

• 🎨 Replace images with animated shapes (Canvas)
• ⏯️ Add Start/Stop buttons
• 🚶 Add pedestrian crossing signal
• 📊 Integrate traffic density logic (AI/ML extension)
