So I'm a bit of a newbie here, but have reached a dead-end on a project I'm trying for class. I made a simple gaming controller using a Nano that will control stepper motors run by a Mega.
I'm using a spliced USB cable to power the Nano from the Mega's power, but I was curious if I could program the other 2 USB wires (Data+ and Data- / Green and White) to act as my RX/TX connection between the two.
I only need to send data (controls) from the Nano to the Mega.
Is this possible without being overly complex?
My backup plan is to run a separate wire taped to the USB for the Nano TX to the Mega RX, but it would be nice to have it all nice and cleanly wrapped up in the USB cable.
