Processing plus Arduino plus fish! :) (Read 1304 times)

Processing plus Arduino plus fish! :)

...

I'm trying to make an interface using an arduino, some photosensors and processing that makes different melodies as fish swim past a group of five sensors. (above is a prototype, using a contact mic though, and no arduino or processing...)

i have some code that i'm trying to mod but i think it might be old and have a few anomalies - either way, it's not working - can anybody help?? Smiley

this is what processing says is the problem...

Well, post the code and then we have a look at it. Looks like something to do with the Minim sound library, perhaps not initialised properly?

Are you sure your sketch finds the sound file?
