Hey, so I'm pretty new to Arduino, and this is my first forum post.
A long time ago I was shown a YouTube video of this guy who had made a "laser harp" where if you broke the stream of a laser with your hand, it would register that and make a sound. I want to supersize this project, making essentially a table (imagine a hollow coffee table with lasers running through it) of 64 lasers and sensors. (It came to that happy number because, since I am a pianist, I decided to make the "strings" 3/4 inch apart, and the table 4' long)
I didn't know exactly where to post this, so I decided to break it up into a few different topics. The first and most pressing concern for me is this: How am I going to use 64 inputs, and what hardware do I need to do that?
I want to use the method described here: http://playground.arduino.cc//Learning/LEDSensor
to make light sensors, so I need to do that for 64 LEDs. How do I go about this? What hardware do I need? Boards, breadboxes?
