    I am trying to set up multiple light sensors that will trigger sound. I'm using both arduino and processing.. Does anyone know what I should put into y code to allow this to happen? The bit that sorta says "if light sensor 1 reads value 0, trigger sound1'. I've tried this multiple times but doing it with more than one sensor doesn't seem to work. Hope someone can help or direct me where else to look!
