Project Title
Death Race - A car racing game using FreeRTOS
Git Link - [1]
Abstract
Real-time adaptation of computer games can content the users’ abilities, skills and also enhance the players' engagement and immersion. We are planning to design a car racing video game between two players. There will be car-race tracks for each player and the player can shift horizontally on the track. Each player can move on the track (RGB LED Matrix Display) by tilting the SJone Player boards. The players will encounter two kinds of obstacles during the game- square obstacles and triangular obstacles. The score for a particular player is incremented for collecting the square boxes and it will be decremented every time when it hits the triangular obstacles. The obstacles are generated randomly and the criticality of the game (randomness of obstacles) increases with time. The game UI will have user options like - indication for players connectivity, start and quit the game. The individual player score will be displayed and updated from time to time on the LCD Display Matrix.

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.
Player Module
Player Module is responsible for sending the accelerometer sensor values from the two player consoles (SJOne boards) to the Master Module (SJOne board) in order to horizontally move the cars left or right of respective players on the display (RGB LED Display Matrix).
Hardware Design
Discuss your hardware design here. Show detailed schematics and the interface here.
Make diagram made in the book and attach image.......
Accelerometer
SJOne board has MMA8452Q sensor which is a low-power, digital output 3-axis linear accelerometer with an I2C interface. Accelerometers are used to find the tilt angle of the device with respect to the earth, by measuring the amount of static acceleration due to gravity.
By incorporating more intelligence from movements and tilt positions, the accelerometers have had a significant impact on user interaction. Most motion-based games are derived from analyses of static acceleration, which are based on gravity to determine the change in tilt angles. Accelerometers provide a new way for navigating, scrolling, and displaying information and thus, provide entertainment in motion-based games. In this project, accelerometer changed the design of the Player Module by minimizing the need for buttons on the board and including motion inputs.
Hardware Interface
In this project, the on-board accelerometer sensor (interfaced on the I2C2 Bus) is used to detect the left or right movements of the board by calculating the tilt angle. The change in the acceleration sensor values due to the orientation of the Player Module boards, in the left or right direction, is used to horizontally move the cars of each player on the RGB LED Display Matrix. The accelerometer sensor values are wirelessly sent to the Master module. Depending upon the sensor values received by the master module from the Player Module, the master module displays and moves the cars on the display in real-time.
The board needs to be held in such a way that, the X-axis is pointing to the right, Y-axis in the front away from you, and Z-axis facing upwards against the ground. On tilting the board left or right, we get left, straight or right orientation values. Y-axis remains constant since we rotate the board across the Y-axis. Only, X and Z axes change and so the angle is dependent on x and y values. The angle is given by:
angle = sin(z/x) where, x = X-axis values of the accelerometer
z = Z-axis values of the accelerometer
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.
Attach flowchart made.......
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.

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.
