Overview Problem Definition Design Objectives Block Diagram Design Testing & Programming Goals Budget Project Timeline Kendra

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

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 Kendra

Block Diagram BOBBY!!!!

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

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) Bobby

Anode & Cathode Mapping Bobby

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

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

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

Budget Parts Cost Arduino Mega 2560 Microcontroller $65 RGB LEDs or Single Color LEDs $80 Plexiglass for casing $30 Decoders (2-to-4 & 3-to-8) $15 General Components (resistors, capacitors, transistors, etc.) $70 Breadboards $20 Shipping and Handling Total $310 Matt
