Project Title
Hand gesture controlled multiplayer game
Abstract
This project involves implementation of a wireless and hand-gesture controlled multiplayer ping pong (2D) game using the Adafruit's 16x32 RGB LED Matrix. It incorporates the on-board RF Nordic wireless transceiver for wireless communication and the on-board acceleration sensor to translate the hand movement into the slider movement on the display.

Schedule
Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

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.
Accelerometer Sensor
The SJOne board has an accelerometer which is interfaced on the I2C2 bus. Accelerometers are electromechanical devices that sense either static or dynamic forces of acceleration. Static forces include gravity, while dynamic forces can include vibrations and movement.The measurements are on 3-axis and these values can be calibrated to find the desired values.
In our project, accelerometer is used for detecting the up-down movement of the wrist. We are using accelerometers on two SJ-One Boards for gesture recognition. The movement from accelerometer sensor will be used to control the slider movement on the RGB LED Matrix.
Wireless Module
Nordic wireless chip nRF24L01+ is interfaced with SJone board using SPI bus protocol.
Hardware Interface Diagram
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:
<Bug/issue name>
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?
Project Video
