I need to build a system where I have to control 4 or 5 small solenoid valves independent of each other using LabVIEW. I have two options: 12 V DC, 2W or 12/24 V DC, 6W. I am really new to LabView and interfacing. So this may sound dumb: 1.Do I need Arduino or some other kind of embedded system for controlling the valves? Or labview has some kind of module for that? 2.Will each of the valves need separate power source? Any suggestions are welcome. Thanks
