To connect an Xbox 360 controller to an Xbox One, there are adapters. However, these adapters cost as much as a new controller.
Luckily for us, there is a completely free technique to do this without an adapter. For this you need a wired Xbox 360 controller, a computer, and a few minutes. You just need to follow the following steps:
You have to go to the Microsoft Store and install the application "Xbox console companion“.
After starting the application, you must log in to the Microsoft account that you use on your console.
Once on the home page of the application, click on “Login” at the bottom left of the screen. Then, in the “Add device” window, click on “Connect” to choose your console. All you have to do is wait a few seconds for the connection.
Connect your controller to your computer via the USB port. On the app, click on “Stream”. A login page with your console will appear. Wait a few seconds.
The connection is now complete. On your computer, you see the same as on your Xbox One. Now you can use the controller on your console.
