I wish we didn’t have to have such a long topic just to get the forum to accept it.
So, I like the idea of having my Panels separated with a left and right side similar to the example from the MKII version shown on youtube. However, I would probably make the bottom sections connect to the vertical portions. So having two L shaped boxes one on each side of the monitor.
When OIS starts it connects to my Arduino just fine and I can play about with it. I wondered though, does OIS connect to any number of Arduinos or simply the first one that responds?
If OIS responds to multiple Arduino’s, I don’t really have to run cables between both panels but instead, use two USB connections to the PC.
