Introduction

In this project we created a racing car game with an analog joystick input to control the car's speed and direction. The SD card reader is used to store the sound file of the project which is output by the Class D speaker. The uLCD is used to display the game and the SD card slot behind the uLCD is used to store the picture of the loading and fail screen. As the game start, the car is travel at a speed which could be controlled by the user. The user will win the game by travel a certain distance and dodge some randomly generated obstacle. If the car hit any obstacle the game will display the losing screen.
