I'd like to build a little project where I can "press" the various buttons on a game controller. I plan on opening up the controller case and closing the circuit of each button as needed, rather than building something that has to physically press down on the buttons.
How can I achieve this using a breadboard? I think I need a relay, probably many? Do I need any resistors? There's 6-8 buttons on a controller.
Eventually I will use an Arduino to control the logic. For now, I'd be happy if I can "press" a game controller button by just connecting a battery or something.
