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

Design And Solutions

Steps to Build the EBOX

1. Program the color patterns

2. Upload the code to the Arduino

3. Plug leads into the hardware

4. Solder external power source to lights and Arduino

5. CAD box to hold the hardware

6. Assemble table

7. Secure lights around the underside of the table

8. Plug in power source adapter to an outlet, place a speaker near the microphone, and enjoy!
