Hello,
I have this idea for using a computer for an art project, but i need or want to use, many arduinos connected to different usb ports,
so the question:
are there any issues for doing this?, if I have 4 usb ports, can i connect 4 arduinos?, if I want to use processing, is this capable of handling say one arduino for music interaction with sensors and other for video? and may be other for motors or lights?
Thank you
In Windows each one will show up as a different COM port. I have connected 2 Arduinos at the same time with no problem.
You will need to make sure and connect the same Arduino to the same USB port each time so that it gets the same COM port assignment. Otherwise you might end up programing the wrong one or wonder what happened to COM4 only to find it's now COM9.
I haven't played around with Processing enough to answer that part of your question.
Processing allows you to specify the name of the port, this will be different for each USB you plug in so you can control it that way. The normal default in a lot of processing code is to use the first port on the returned list as that is the last thing that was plugged in so you will have to do things properly.
