Project Proposal

Introduction

Statement of Purpose

We are creating a LED sound display that is connected to a speaker system. The device will receive audio input from a 3.5 mm and use an Arduino to convert the sound information into a colorful display of lights representing an equalizer. The audio will then be outputted into two giant speakers for maximum listening pleasure.
