Project Proposal
Overview
We created an audio responsive LED lighting system integrated on a desk that can be used as a fun addition to one's home entertainment and lighting systems. The EBOX has 3 modes that the user can set with a tap of a touch sensor to customize the dynamic light patterns to fit any mood.

Objectives
- Use an Arduino to implement a Fast Fourier Transform(FFT)
- Integrate the FFT through the Arduino with our LED lights
- Make the LED lights respond music with a specific, non-random color scheme
- Have the Light intensity change with the decibel level of the music
- User interface
Challenges
- learn Arduino
- Soldering
- learn complex circuitry
- carpentry
- writing the code and interfacing the Arduino with the LEDs and Sound receptor
- Learn to not short our entire project
- Learn how to use transistors
- Make sure nothing blows up
- Staying under budget
