Use all your old-school game controllers with the turn of a dial
IT professional (and Arduino cap fan) John Milner had a minor problem. While his retro gaming setup could emulate a wide variety of systems and games, it was still missing the tactile feedback of the original controllers. Rather than “submit” to playing with only an Xbox 360 controller, he developed the Multijoy Retro Gaming System that can change gamepads with the turn of a knob using an Arduino Micro.
The resulting system lets him not only choose the original controller for each game, but if you want to mix things up and see how Super Mario Bros. would feel on a PlayStation 1, or even a Genesis controller, you can do that too! It also features shortcut buttons on the new console.
The Arduino presents itself as two joypads with native plug-and-play support for Microsoft Windows 7+ and Linux/RetroPie. The selector is simply a ring of LEDs with a potentiometer in the center, using the knob will move the lit LED to the desired controller pictured in that position, a simple system with an unexpected bonus of being a little retro in its appearance.
