Hi, I'm trying to build an RGB matrix driven etch-a-sketch of sorts. What can I use for the input knobs? Can I use motors or stepper motors or something? I need to be able to turn in either direction forever and to be able to detect how fast it's being moved. I'm using this with an Arduino Mega.
this type is great for knobs and spinners, ez to hook up and there's even a library
or if you want to take a tiny bit of load off the cpu you can use this, which was done up as a mod for a non reprogrammable pic pong kit (to add paddles)
It also just occurred to me that these could also be used for some kind of "pong" type of game. I'm pretty sure the original pong game had wheels that spin on the controllers.
I think I've seen some arduino / pong projects around
