I am drawing out diagrams for a project I want to do to involve loads of buttons in a 8x8 grid but… I don’t know how to go about driving them, if someone could show a simple way to not use a lot of pins to accomplish this I’d be happy as then I’d be able to continue drawing out my plans.
This is my first electrical project, so loads of learning to do
No python allowed in this project. The point is for me to code a microcontroller to do something on my own
