“Works a treat on an Adafruit RP2040 feather. The standard library was too temperamental on my standard Adriano UNO due to limited memory. but Adafruit warn you of that.”
“You plug it in download the library, find a Wii nunchuck. It just works. You can also use this with other Wii peripherals that use the same connection. I haven't fully tested that part of it yet. As still finding my classic controller.”
“Simple and effective. Has no protective guards so be extremely careful - it is trivial to connect it upside down & you will fry something. Really could use some basic protective shielding to avoid this”
