/diy/ - Do It Yourself

I know literally nothing at all about electronics. I can solder two wires together and that's about it.

I want to wire piezo components to the buttons of a NES controller. I know I also need the electrical equivalent of a noise gate, whatever the fuck that would be, between the piezo and the controller so it's not constantly sending signal due to ambient vibration.

A) How do I do this or
B) If you don't want to spoonfeed me, where do I start learning what I need to accomplish this?
