Hey my guys sorry if I don't make sense or so very tired and been tryna figure this out, so I have set alittle project for myself for the fun of it. I want to create a circuit, I have a bread board, soldering iron and rotary encoder and I was wanting to create a circuit that connects to my pc via usb and powers it and also allows my pc to use it, what the project is to start off I want to make it so the rotary encoder (believe I got the correct thing for the task) if I turn it left for example it'll scroll down on the computer like a computer mouse scroll wheel etc. I was wanting to start there and slowly add to it but I was wondering what else would I need to complete the project example like a aduino (sorry bad spelling) to run a script for the scroll and if needed what one would be best and powering wise thank you very much
