## 🚀 Features  
- Play retro games like Tetris, Snake, and Space Invaders directly on ESP32.  
- Compact design using **ESP32** and **ILI9341 TFT display**.  
- Low-power consumption and portable build.  
- Built-in joystick and push buttons for control.  
- Easy to program and extend with additional games.

## 🛠️ Hardware Requirements

| Component              | Quantity | Description |
|------------------------|----------|-------------|
| ESP32 Dev Board        | 1        | Main microcontroller for game logic and graphics |
| ILI9341 TFT Display    | 1        | 240x320 pixel display for game output |
| Joystick Module        | 1        | Used for player navigation and control |
| Push Buttons           | 2–4      | Action buttons for gameplay |
| Breadboard & Wires     | As req.  | For circuit connections |
| Power Supply (5V)      | 1        | USB or external power source |

---

## ⚙️ How It Works  
1. The **ESP32** runs the retro game logic programmed in Arduino C++.  
2. Game graphics are rendered on the **TFT ILI9341 display** using SPI communication.  
3. The **joystick module** provides analog values that are read via ESP32 ADC pins for directional control.  
4. **Push buttons** serve as action keys (jump, fire, rotate, etc.).  
5. The ESP32 processes player inputs and updates the display in real-time, creating a smooth gameplay experience.

## 🧠 Troubleshooting

| Issue                         | Possible Cause | Solution |
|-------------------------------|----------------|----------|
| Display not powering on       | Wrong wiring or no 3.3V | Check TFT power and ground pins |
| Screen flickering             | Loose SPI connections | Ensure wires are firmly connected |
| Joystick not responding       | Incorrect ADC mapping | Verify pin assignments in code |
| Buttons unresponsive          | Floating inputs | Use pull-down resistors if required |
| Game lagging                  | Low SPI speed | Increase SPI clock in code |
