I constructed the arduino-LED system and mapped the inputs to their proper locations. Additionally, I worked on the microphone data plot on C#. For the arduino, I helped figure out the proper way of serial input.

I configured the C# program to communicate with the Arduino UNO accordingly. This was achieved by writing output generated from visual studio into a serial port, running at a rate of 9600 BAUD, and reading this output from the Arduino board directly

Hubert Yang
I worked on implementing the fourier-transformation algorithm and creating the graph of frequencies and magnitudes from the inputted data. I also helped in transferring this data through the serial port to be run on the Arduino.
