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

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
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
Building
 Solder Cube
 Check solder points
before adding next layer
 Construct LED driver
circuitry
 Wooden base
 LED Casing
Testing & Programming
 Major part of project
 Testing- results will not be qualitative
 Programming
 Get acquainted with Arduino software
 Lighting- patterns
 Music- spectrum analysis
Goals
 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
