I apologise in advance if this question is not right for this Stack or if it has been answered before but here goes. I have been learning C/C++ using the Arduino Uno and have gotten the hang of it now (I have knowledge of other programming languages so it wasn't too difficult to get in the rhythm). I was wondering how I would go about creating a standalone solution if I wanted to display information on four or five displays similar to These. I would pull data from a network to display on them too so I would also need to accommodate an ethernet or WiFi shield.
I appreciate any help or pointers in the right direction that can get me started on my journey to creating some custom embedded systems (if that is indeed what I am describing).
