Gamepad Test

Controller problems explained

• Stick drift: an axis reads above ~0.10 with the stick untouched. Clean around the stick and recalibrate. Persistent drift usually needs a replacement stick module.
• Button not lighting up: the contact pad is worn or dirty. Clean it or replace the controller.
• Controller not detected: press a button after connecting, since browsers only reveal controllers once used. Try another USB port or cable.
• Works with PlayStation, Xbox, Switch Pro and most generic USB or Bluetooth controllers.

How this gamepad test works

Your browser includes a Gamepad API that reports every button and stick on a connected controller. This page reads that data many times a second and displays it. Each button number lights up while you hold it, and each stick or trigger shows a live value, so you can see exactly what the controller is sending to a game.

Reading the results

• Buttons: numbered 0 and up. Press each one and check that the matching number lights up.
• Axes: values run from -1.00 to 1.00. Left stick left/right and up/down are usually axes 0 and 1, and the right stick axes 2 and 3.
• Resting position: with your hands off, the sticks should read close to 0.00. A steady reading above 0.10 means drift.

Connecting your controller

Plug it in with a data-capable USB cable, or pair it over Bluetooth, then press any button. Browsers hide a controller until it is used, which is why it may not appear straight away. Chrome and Edge support controllers best.
