Great, thanks for the advice and extra resource.
I have a very clear project in mind, manipulation of video using gestures (or instead a smartphone/tablet as an touch interface). The project already functions in the web, but I want to up the resolution of the video, which I think TD can probably handle HD. I’m on pretty low resolution imagery in the web.
I have good experience with Processing/P5.js, and a little with Max, so I hope I just need to sit down with the right tutorials and guides and follow along. (I really hope it is that easy for me!!).
Edit: I know from when I first tried to learn arduino, that just doing tutorials didn’t help anything stick. To @arctor023 's point, it only really clicked when I had a well defined outcome I needed to create; then it all fell into place.
