[ELECTRICAL] I am planning a project and need help (beehaw.org)

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

Can I reply on beehaw? Testing 1 2 3.

It's essentially a custom mechanical keyboard, so there are plenty of resources from that community.

Wire them in columns on 1 pin, and rows on the other with diodes between each switch on the rows. Then connect every row and every column to a microcontroller. Teensy, Arduino, whatever you like or can find pre-existing software for.
