If you’re like most people, you probably have at least two gaming devices in your home: a PlayStation 4 and a Nintendo Switch. But if you want to play games on the go with your PS4 controller, you’ll need to connect it to your Switch. Here’s how to do it. First, make sure that your Switch and PS4 are both turned on and connected to the same network. If they aren’t, you can use the Nintendo Switch Online app or a web browser on a PC or Mac to connect them. Once they’re connected, open the Nintendo Switch Online app and select “System Settings.” Under “Devices,” select “Add New Device.” Select “PS4 Controller (Original)” from the list of devices and press OK. Your PS4 controller should now be listed under “Devices Registered for Use with this System.” To use it with games on your PS4, just open the game and press the button corresponding to the direction pad, joystick or buttons on your controller. For example, if you have a DualShock 4 controller, pressing the D-pad will move you around in games like Uncharted 4 or Call of Duty: Black Ops III. ..
