Greetings,
I am working on an interactive audio installation. I intend to trigger different sound samples from my laptop, and a hardware sampler, using analog signals (e.g. motion detection, light detection, etc.). I have an analog to midi converter that will run my samplers. But there is one problem, the analog inputs will only take "free contacts," I guess this means basic switches. The interface's manual specifies that no voltage should reach the terminals of the analog inputs. Because I want people walk through an area, I can't use typical contact switches.
I guess this sounds like a simple presence detector project, but I am not sure about the type of contacts I can use to run my gear.
Thanks for any help.
Hugh
