Abstract

Bubble shooter is an arcade game that has bubbles or balls present on the screen. The bubbles are of different colors and the goal is to clear them by forming a group of bubbles (3 or more) of the same color. Points are earned upon clearing the bubbles and increases with the number of bubbles cleared in a single shot. The player wins upon clearing the screen and loses when the bubbles touch the bottom of the screen.

Hardware Design & Implementation

Analog Joystick

An ADA512 2-axis Analog Joystick and Button is used for controlling the movement of the launcher and shooting the ball. The data from the joystick is read using the ADC pins of the SJTwo board. The button switch is detected using a digital pin on the board.

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 the 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 the exact code, but you may show pseudocode and fragments of code. Keep in mind that you are showing the DESIGN of your software, not the inner workings of it.

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 implementations.

Testing & Technical Challenges

Describe the challenges of your project. What advice would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to the 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 learned from this project. How has this project increased your knowledge?

Project Video

Upload a video of your project and post the link here.

Project Source Code

References

Acknowledgement

Any acknowledgment that you may wish to provide can be included here.

References Used

List any references used in the project.

Appendix

You can list the references you used.
