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

4. Design Objectives Build cube of LEDs Program 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

6. Design Goal: 8x8x8 single color LED or 5x5x5 RGB LED
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
Bobby

7. 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)

9. Building Solder Cube Construct LED driver circuitry Wooden base
Check solder points before adding next layer
Construct LED driver circuitry
Wooden base
LED Casing

10. Testing & Programming Major part of project
Testing- results will not be qualitative
Programming
Get acquainted with Arduino software
Lighting- patterns
Music- spectrum analysis
Matt

11. 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
Matt
