Overview

3-D cube of LEDs Audio/visual effects in real time Completed within budget Presented at URC in April

Problem Definition

Build cube of LEDs 8x8x8 single color LEDs

or 5x5x5 RGB LEDs

Program LEDs To light up in different patterns To change in sync with music playing

Control with computer

Design Objectives

Block Diagram

Start with 3x3x3 single color LED cube Experimentation Learn how to use Arduino microcontroller Work on light and music programming Mimic expected design for second cube to

become familiar with final circuit on a smaller scale

Design

Goal: 8x8x8 single color LED or 5x5x5 RGB LED

Enabling LEDs

Design does not allow for LEDs in separate columns to light simultaneously

Flash LEDs faster that human eye can detect (persistence of vision)

Anode & Cathode Mapping

Solder Cube Check solder points

before adding next layer

Construct LED driver circuitry

Wooden base LED Casing

Building

Major part of project Testing- results will not be qualitative Programming

Get acquainted with Arduino software Lighting- patterns Music- spectrum analysis

Testing & Programming

Size 3 single color cube Size 8 single color or size 5 RGB cube Effective light and music synchronization

Programming development has no definitive end

Dependent on time and knowledge of Arduino software
