Hiya
When I want to interface between a component and a computer I use my raspberry PI 400 and it’s GPIO. It’s good stuff.
Sometimes I wish I could just GPIO out of my PC.
Last time I needed to do that I grabbed an Arduino nano, wrote some code that took binary instructions via USB serial which punched out GPIO instructions. Fun and effective but took ages because I was inventing a protocol.
Has someone made a GPIO tool that USB-Cs into a computer?
