In an effort to increase the distance of busy little hands from vintage hardware, I created an adapter that lets a WiiMote be used as a wireless controller.  The current hardware supports two joysticks (directions, trigger, and both potentiometer signals) and uses an ESP32 for the bluetooth connection to WiiMote.  Proof of concept Arduino code is working with one WiiMote that outputs to both joystick connectors.  More details on hardware and design here: https://hackaday.io/project/179786-
