Hi there, thanks for the response, here are some answers:
What are the inputs to the system? How should it decide when & where to direct the air flow?
I would like to do it so have an arduino system is hooked up to a PC or MAC that controls when and where to direct air flow. there would be one source of air flowing that is fed into a manifold that branches out into many tubes with valves that would need to be mechanically controlled by actuators that are controlled by the arduino... commands from a computer will execute some command that opens/closes valves with a constant source of air going the whole time,
What are the outputs of the system? Are these high-pressure air valves, or duct dampers?
not really sure
What level of control do you need? Simple on/off control, or do you need to balance/control the flow rate in each pipe?
