Hi all,
Just wanted to share a project I worked on some time ago, and I recently polished it a bit before publishing the code. Based on a previous project, I built a cabinet with an RGB LED Matrix and a PiTop[4], using the potentiometers and buttons as the controller of the games.
The Pong game works quite well if the buttons are not connected to the PiTop[4]. I suspect there might be a conflict on the GPIO between the RGB Matrix and the digital inputs of the board.
Nevertheless, it was a fun project that I built with my kids (the “gamepads” are their contribution 
).
