I know that the communication between two arduino can be setup with serial ports TX/RX, but now, because of pratical installation issues, i need to prepare an arduino "master" able to send and receive messages via USB cable to another arduino (via USB).
Is it possible ? I know that usb communication must have HOST and CLIENTS and I know arduinos are only usb clients.
Could I solve my problem with this usb host shield?
Does anybody evere used these USB HOST shields to communicate with another arduino?
Thank you very much!!
