Project Title
2D Plotter
Abstract
The 2D Plotter is a printing device. The printing device draws in two dimensions in a limited square space. Our project intends to draw a square from a computer-aided design file. Although more is possible, the 2D plotter will only draw a square.
Objectives & Introduction
Show list of your objectives. This section includes the high level details of your project. You can write about the various sensors or peripherals you used to get your project completed.
The Objectives of this project are as follows:
1. To have the SJSUONE board run the servo-motors through GPIOs to create movement in the x and y direction. 2. To build a wooden enclosing to house the SJSUONE board and servo-motors. 3. To extend the wooden enclosing to include a platform for printing, which would include rails in the x and y direction, a print top for printing, wood to move the pen and the attached pen itself. 4. Program the SJSUONE board to read and write a simple Computer-Aided-Design file from an SD card, issue some error or initialization signals and output the design on the print top.

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.
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:
Wifi Connection Issues
Many wifi connection issues were encountered. To solve this problem, a dedicated task was created to re-connect to wifi if the connection was ever lost.
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?
Project Video
Upload a video of your project and post the link here.
Project Source Code
Send me your zipped source code and I will upload this to SourceForge and link it for you.

None. Preet Kang and Dr. Ozemek did not really help us. They just graded us. If only they spent more time helping us rather than grading us. Just saying.
