Hi
This is not a real project, it's begging with a case study: how to use a arduino, leds, a lcd and linux devices in order to display some info in real time.
As dd-wrt is linux, it was easier to me to make test in one of my router, at the end I got some time to make it fancy.
I just posted some pictures, and code, later will post some details about wiring and how it was made.
I'm not a coder, arduino code is very basic, the goal was not programming, but obtain data from linux devices and send data to the display and to LED.
