Pinball

Abstract

For our project, we wanted to design a pinball machine. We wanted to incorporate bumpers, a 7 segment LED display for the total points earned, a sound system that would go off after each bumper was hit, and LEDs around the machine. In addition, we wanted the user to be able to turn the machine on and off, as well as control the flippers.

Objectives & Introduction

Below is a high level list of the minimum functionality features our project will include.

  1. Launching Pin ball (mechanical)
  2. Play sound/music when sensors are triggered
  3. Flipper Controls (mechanical)
  4. Ball detection sensor
  5. Score Incrementation as sensors are hit
  6. Display score on 7-segment display
  7. Game Over announcement

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.

Hardware Constraints

  • Power Supply: 24V / 2.1A
  • Pinball size: 0.5 inch diameter / 8.4-8.5 grams each
  • Pinball frame width: 1.5 feet
  • Pinball frame length: 2 feet
  • Pinball frame height: TBD
  • Angle: ~5 degrees inclined

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.

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:

My Issue #1

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?

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