## 🔍 Troubleshooting

### Common Issues

1. **Permission Errors**
   ```bash
   sudo usermod -a -G gpio,i2c,spi $USER
   # Then log out and back in
   ```

2. **I2C Not Working**
   ```bash
   sudo raspi-config  # Enable I2C
   sudo i2cdetect -y 1  # Check for devices
   ```

3. **GPIO Already in Use**
   ```python
   import RPi.GPIO as GPIO
   GPIO.cleanup()  # Clean up before running
   ```

4. **Web Server Port in Use**
   ```bash
   sudo lsof -i :5000  # Check what's using port 5000
   # Or use a different port in FlaskServer(port=8080)
   ```
