So I have been watching a few videos on youtube and people use HUD's on their computer to control led's, so if anyone knows a way to create a HUD that would be great!!
Perhaps you have links to whatever it is you have been watching? What part does the arduino play?
Did you mean "HID" (Human Interface Device)?
A HUD is a Head-Up Display, and is a passive display, so doesn't control anything.
You might be right AWOL sorry for the confusion im really new to arduino! So yeah
