Hello,

I have got a project [b]video and painting[/b] and I want to present in a space.

I want to use a sensor on Arduino to star video when entering a man in space. I don't want one video but I want others video.How to put others video? Also, How to use a sensor when entering a man in space so that to star video? Each video.
I need your help to use with arduino and processing. I don't know Arduino and I am not good processing.
