TEAM 10: Seeing Sound!
Spring 2011


MEMBERS


PROJECT CONCEPT

Our project will create an entire light show on the spot based on any sound input. The prototype will take in any sound form, from a song to a person talking, and use LEDs to make a matching light show.

MOTIVATION

iTunes and other music players make visual shows to go along with songs, but these players only use songs, and they have to look ahead in the song due to a delay from the song to the visualization. Our prototype will be able to create a light show from any sound in real time.

RISKS & MITIGATION STRATEGIES

                             Risk

                       Mitigation

2 shields need the same pin on Arduino

Jump the shields to other Arduino pins,
make changes to pins used in software

Audio signal being diminished by audio
splitter

Add amplifier in audio splitter

Microphone breaks

Use iPod for audio input

Speakers not being loud enough for demo

Use headphones

Microphone picking up background noise
during demo

Use iPod

LEDs are not bright enough during demo

Turn off the lights in Rangos :P

Canít get lighting DMX protocol working

Build our own LED matrix

DMX shield doesn't work

Build our own DMX shield

TIME LAPSE

To be completed.
