Been working on Elden Ring Seamless Co-op with some friends - actually two groups, but one plays intermittently so I fork my character to another slot every time. Trying to get my SO to play PlateUp but not much luck there. Also playing Hades Star on mobile but it just makes me want to play EVE hahaha.
Yup, pretty much this. I have a small touchscreen Arduino device that I keep plugged into my PC. When I hit a button on the touchscreen it sends some text over serial (which is really a USB wire). I have a Python script on the PC that continuously reads from the serial port and parses the received data to figure out what to do. Specifically it tells my Discord bot to play a sound :)
