Projects General Guidance

Hello all,

I am in need of some advise.

To the point. I have read and searched about making an Arduino Leonardo into a game controller. I currently have a Mega and a Leo and in a little confused.

I have made my Leo work as a game controller, displaying 32 Buttons and the axes but what I am confused on is the number of available pins on the Leo.

I am new to all this but a quick study. Problem is The internet has to much loose information on the subject.

The Questions
Can you have 32 working buttons 3 axis and two sliders with the leo?
Is is a point in how you wire the buttons to achieve the 32 buttons?

Thank you in advance

You can have as many inputs as you want if you use port expander chips or parallel in serial out shift registers.
