Serial Output to Arduino LED Display

Question

I recently completed this project with my Arduino (a fairly new hobby for me):

http://www.instructables.com/id/Make-a-24X6-LED-matrix/?ALLSTEPS

I can change the code to make whatever messages I want scroll accross the matrix but I thought it might be cool to have live information, like stock quotes, scroll accross. I think I could figure out how to do that except I would like to use it at work where there are lots of firewalls in place and I doubt Arduino software is on the approved list of programs. Is it possible to send messages to the Arduino through a USB without installing any drivers?

Answer 1

No it is impossible because data in Arduino is sent via serial command, the USB is only for convenience, but arduino work with FTD driver that emulate a serial connection. You should choose another type of connection bluetooth or wifi. Hope this help you.
