Project Title
Abstract
The purpose of this project is to create an automated chessboard, displaying moves made by users playing chess. The web application server will be hosted on a Beaglebone Black. Users log in and play a chess game hosted using Node.js. As moves are made on the web app,the pieces will be physically moved on the chessboard.

Parts List & Cost
Give a simple list of the cost of your project broken down by components. Do not write long stories here.
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
XY Plotter Hardware
Computer Aided Design Chess Pieces
Electromagnet
Hardware Interface
The chess game is hosted on a Beaglebone Black (BBB). The BBB is a open-source hardware single-board computer that runs an embedded Linux. The game is ran in Node.JS, and ran as a local host such that any computer device can connect to it and play the game. As plays are made on the chess game, the changes in moves are processed, and a string is transmitted over UART to the SJ-One board. The SJ-One interprets the string, and translates these to physical moves. By commanding the stepper motors, it moves chess pieces to reflect the changes made in game.
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
Stepper motor drivers are very easy to fry.
As current flows into a stepper motor, it stores this energy in magnetic fields. The reverse is true. That is, when current is no longer supplied to the motor, the magnetic field collapses creating current, known as back EMF. The stepper motor drivers contain circuitry to protect itself from this back EMF. However, adjusting the current setting or unplugging the stepper motor driver while engaged WILL damage the driver.
We fried two sets of stepper motor drivers.
My Issue #2
My Issue #3
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?

Special thanks to Hugo Quiroz. He provided mechanical knowledge, access to laboratory and equipment, and dedication to our project. We wouldn't have our chess board if it weren't for him.
Special thanks to Professor Peter Reischl. He went out of his way to educate us on constructing the electromagnet. Without him, we wouldn't have our electromagnet.
