Hello,
Im quite a novice when it comes arduino so please excuse me if this is a bizarre question. I have a display monitor that I got second hand but it’s basically a brick, it requires an app to work. Is it possible for me remove the mother board and simply connect an arduino and power to it and turn the display on? I’m only using this for USB playback.
The Arduino does not have a display driver so it will not drive a monitor of any type. Typically it communicates via USB to a host computer running the Arduino IDE. The IDE communicates with the PC for input and output. The IDE running on the PC uses the PCs keyboard and monitor.
If you can get this to work with a PC or Raspberry Pi then via the IDE you can use it.
