Final Project: 1. Create and play a simple Snake Game using Python and the Sense HAT emulator. Control the snake with arrow keys to eat food and avoid hitting yourself! • Controls: Arrow keys or joystick directions • Snake grows when it eats food • Food appears randomly on the board • Game over when snake hits itself • Wrap-around edges (snake appears on the other side)
