 == Conclusion ==
 We were successfully able to design the UFO game which has been a classic 8bit game since the induction of game industry. We were able to learn about and implement wireless communications between the controller and the console. While designing the project we faced a few problems regarding software and hardware implementation. The display that was used did not have any organized documentation but we were able to infer knowledge from the Arduino code and the graphics library in order to interface the display to the SJOne board. After the basic game was designed we were very motivated in doing something extra and providing features that were not present in the original game such as varying speed objects and an enemy UFO. Overall, it was a great learning experience but more than that it was extremely fun.
