Hi
totoe!
Unfortunately no. However, since I'm doing Arduino stuff with Construct, I found a path that works for me.
I've just built a custom controller, added the Joystick library and a tweaked sketch to the Arduino Leonardo and then use the Gamepad object in Construct. Seems to work fine!
But it would for sure be nice to have a dedicated Arduino plugin built into Construct.
I found some good youtube videos and made a playlist to help with my project. Maybe it will be useful to you?
