I'm hoping you can help give me some guidance and advice on this project. I have worked with all of these technologies on a smaller scale, but I am embarking on a project that will use many instances of what I mentioned in my title. So I feel there are some issues, warnings and technologies I should be aware of!
I am planning to use 500 - 1000 small 6-8ohm speakers, pir sensors, and leds for an installation. To clarify, that is 500-1000 instances of each of those elements. I don't have specs because I am not quite at that stage. But to give you an idea the leds would be RGB maybe around 12v. About 4 of these groupings would be placed every meter in a grid around some walls.
I would ideally like a centralized system so I can easily program this project. what kinds of technologies should I be looking for to interface all these groups of speaker/sensor/led, to make the wiring and programming simpler? I will have a crew to help me, but if there are some technologies that would make this easier/more feasible I would appreciate your recommendation!
Thank you :)
