-When a user logs into the 'Play' page, socket.io will designate that user to a specific socket. If another user logs onto the play page, they will both be running off the same socket. This allows for the real-time aspect. When the user makes a move a string will be sent to the SJOne Board via UART.

 === Issue #3: Stepper Motor Calibration ===
 The XY Plotter was purchased from MakeBlock. The kit included a portion of code to control the stepper motor. The code is originally written for the Arduino so it needed to ported over to the SJOne Board. However, once the code was ported over, there were several #defines and const variables on the Arduino side that did not match on the SJOne Board. We needed to calibrate the stepper so that it performs exactly how it does on the Arduino side.
 == Conclusion ==
 Overall, it would seem that a lot of effort went into creating a "over-the-top" version of a simple game. However, the chessboard we created draws from the various lessons learned though this class the and years we have been in engineering. A UART driver was implemented between two microcontrollers and ensured that the transmissions were read and properly processed. A driver was created for the XY Plotter from scratch, with all locations being mapped and programmed accordingly. An electromagnet was created, and though ultimately scrapped, it was successful in its intended purpose. FreeRTOS was used to prioritize the tasks of our board in order to ensure that all necessary functions were carried out properly and efficiently. By working on this project, the gap between knowledge attained in class and the actual implementation of these lessons was bridged.

 == 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.

 ===== Tasks and Semaphores =====
-A FreeRTOS system was used to hold our system together. We used 2 tasks. One task was used at high priority (getFromBBB) to store UART strings into a character queue. This was set at high priority because the inputs coming from the web application should not be delayed.
