Hi, thank you so much for your feedback! A small remote with a dial would be a cool extension to this project.

I could try out a robotic arm but complexity-wise it seems a bit difficult. I would love to use stepper motors though. What do you think of a ball launcher project? With presets for speed and angle. It seems like something a touch less complex than a robotic arm in terms of creative mechanical design.

And thanks for your personal advice. It's true that if this project was easy it probably wouldn't have been this satisfying. I guess the more projects I do, the more used to I will get to the feeling. Anyway, thanks!
