-Assume you are writing to someone who wants to know how to use the device.  Show a picture
-of it. Note the importance of soldering the display on correctly. Give wiring instructions.
-Be specific, where do I wire the power?  Where does the clock go, etc.  How is the voltage
-level converter wired in? Show a picture of the wiring.

 This is a very simple code implementation that is only to verify that the matrix works. For a further implementation of the 8x8 Matrix see the Mini Project 4 project here: [https://github.com/draneaw/MiniProject4.git Node.js Advanced Implementation]

 This page details project work done while working on the 8x8 Bicolor LED Pixel Matrix from Adafruit found here: [https://www.adafruit.com/products/902 Store Link]
 IMPORTANT!!! When soldering the led matrix to the controller make sure that it is placed correctly. If it is not, then the device will still communicate but the LED Matrix will not turn on.

−	The current LED Matrix is fully functional except for a minor issue with alignment of the rows. It is shifted up by one LED and puts the top row at the bottom. The former issues encountered with the device was due to a miss-wiring of the matrix to the I2C Part.

-The device relies on the 5V source on the board and to insure functionality an I2C voltage up-converter is used to boost the 3.3V I2C voltage to 5V.
