Hi
I need to connect several arduino to one computer...and I don'( see how to to that with serial...if not having 10 serial ports....Any idea ?
Off the top of my head (ie. I've not tried it), how about using Two-Wire Interface (TWI)...?
Connect 1 arduino to the computer via USB and set it to be the TWI master.
Set the other 9 arduinos up to be TWI slaves and connect them to the master via SDA & SCL (12 and 13 on shield connector I think).
