Can I control multiple arduinos together?

Hi,

Can I control multiple (four) arduinos together through a single computer with usb hub?

Processing consequently sending an array of numbers (ex [7]) and each arduinos get 2 of them (ex. arduino1([0],[1]) arduino2([2],[3]), arduino3([4],[5]), arduino4([6],[7]) …

Thanks!

Yes, for : you can add several Arduinos to your computer using one or more hubs!

I have never used Processing so I can’t tell how it handles the devices.
