i am pretty much newbie with arduino and want to start my first project so i may be asking stupid questions.
My goal is to make usb controller for android tv (running on raspberry pi or s905). I want it rotary, so turning will be "arrow up/down" or "left/right" (i dont know exact android tv menu controlling) and "return" on push. I found this rotary switch on ebay, is it suitable?
To communicate i want to use arduino. I found libraries MouseKeyboard, which might be suitable for my needs, will arduino nano support this library or do i need arduino uno?
Do i need something else, or just connect switch to pins on arduino and plug arduino to raspberry?
As i need this controller to operate in menu, not just in some application, will this work as some mouse or keyboard connected via otg to android and function immediately?
