Multi-Touch LED Matrix Display

Twitter Board with LED matrices here, has Arduino library for text

Place he got led matrices from Sure Electronics. 125 for a big board >.< and less for a lot of 10, but they aren't 5mm, but might not be able to read light data from it. Want 5mm LED's either way

Tom Igoe Arduino Playground tutorial here with simple code. More optimized code here

Mike Cook reading LED's article + theory…got almost all the way there with LED matrix…

Tom Igoe simpler example here on Arduino playground

CMU Student Final Project for Gadgets, Sensors, and Activity Recognition “Laser Command” Final Project. good explanatory overview

Dimension-X.net Best discussion on the internet about this stuff. Series of forum postings.

Paper by Scott Hudson, HCI Prof at CMU. Patent by Jeff Han.

Senior Project at Cal Poly,REALLY EXPENSIVE!! 64×64 pixel board, have to worry about light levels, but pretty good. Need a computer not an Arduino to do that many analog inputs and updates that quickly

Monome leds plus buttons, really spendy but good sources

Peggy…good for graphics but no input

Interactive Game of Life

Tetris with “touch” controls that always light up on the side

Space Invaders…oooohhh… :

Pong, Tetris, Snake, Source Code + Project here

NerdKits Theremin Great example of using two timer counters hooked together for high-resolution audio output. 440.5 Hz is now possible, but you have to do some math first… Try to understand/copy their well documented source code and simple functions.

Example of really good tones with reverb with source code: Physical Tone Matrix

Buy red/green displays off of Sparkfun here $7 each . Maybe get some analog muxes too to read/control everything here $3-4.
