[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

If you want something simple to set up, I've used the Adafruit Trellis Neo in the past, you can solder many many boards together in a grid and communicate over I2C or USB to a microcontroller. The only hitch is that control requires CircuitPython, which can be a pain to install.

No python allowed in this project. The point is for me to code a microcontroller to do something on my own

I2C is a simple standard, you can manually control it if you want.
