[ELECTRICAL] I am planning a project and need help

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....

paul,

@CinnamonTheCat
Take a look at some keyboard matrix designs.
This is a reasonable guide:

Hope that helps :)
