Abstract

Dodge Cars is a fast-paced action game where players control a vehicle to avoid collisions with incoming obstacles. The objective is to maneuver the car left or right, dodging other cars or objects as they approach. As the game progresses, the speed of obstacles increases, adding difficulty. The game utilizes a 64x64 LED matrix display for visuals, with an SJ2 board for processing. A button allows players to access the menu, navigate, and pause the game (or optional photosensor). An ultrasonic sensor detects if the player is sitting too close to the screen, warning them to adjust their position. An accelerometer is used to control the left and right movements of the player car. The final score of the player will be displayed at the end of every game and a speaker attached to the board will generate the game sounds.

Introduction

Dodge Cars is an engaging and fast-paced action game designed to test players' reflexes and coordination. Players navigate a car through a dynamically changing environment, dodging incoming obstacles that become increasingly difficult to avoid as the game progresses. This interactive experience leverages modern hardware and creative gameplay mechanics, delivering a fun and challenging game suitable for players of all ages.

The game is powered by a 64x64 LED matrix display that provides a vibrant, retro-inspired visual experience. An SJ2 board acts as the central processing unit, seamlessly handling the game's inputs, outputs, and real-time logic. Players control the movement of their car using an accelerometer, adding an immersive, physical dimension to the gameplay. Safety and accessibility are also prioritized, with features like an ultrasonic sensor to promote proper player posture and a button or optional photosensor for intuitive menu navigation. To enhance the overall experience, a speaker generates immersive game sounds, and the final score is displayed at the end of each session, encouraging replayability.

Objective

The primary objective of this project is to develop an interactive game system that combines hardware and software components to deliver a compelling gaming experience. Key objectives include:

• Design an engaging game loop where players must dodge obstacles using precise control of a car, with increasing difficulty as the game progresses.

• Utilize modern hardware components like a 64x64 LED matrix for visuals, an accelerometer for motion control, and an ultrasonic sensor to enhance player safety.

• Provide intuitive user interactions through menu navigation using a button or photosensor, along with clear audio-visual feedback from the speaker and display.

• Promote player engagement and challenge by showcasing the final score at the end of each game and encouraging improvement through replayability.

• Integrate safety measures by alerting players if they are sitting too close to the screen, fostering healthier gaming habits.

This project aims to blend creativity, engineering, and user-centric design into a fun and immersive gaming system that highlights the potential of embedded systems in interactive applications.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

• LED Matrix:
  • 1. Initialized LED matrix connected pins to board IOs.
  • 2. Designed matrix driver for screen display by reading an matrix.

• MPU6050 Accelerometer:
  • 1. Initialized 2 ADC channels for taking the x, y and z reading from the sensor and input the readings into the LED matrix gameplay.
  • 2. Decoded voltage readings into joystick movement commands.

• Buttons:
  • 1. Initialized several gpio for taking binary command from button pressed.
  • 2. Enabled interrupts for each botton pressed.

• Mp3 Player:
  • 1. Initialize using UART3.
  • 2. Set device with selected sd card and volume.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

<Bug/issue name>

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
