Gamepad Tester
Test a game controller: every button and trigger, the sticks with their drift and circularity, and the vibration
Connect a controller, then press one of its buttons
By USB or Bluetooth. Browsers show a controller to a page only once a button is pressed. What it sends stays in your browser.
The browser doesn't know where this controller's buttons are: they are listed below as the controller numbers them.
Sticks
Left stick
Right stick
Turn each stick slowly around its edge a few times to trace it: the farther the outline from the circle, the higher the error. Then let go:
where it rests is its drift. Games ignore a small circle around the center, the dead zone, often 0.1 to 0.25 wide, so drift under it goes unnoticed.
Vibration
100%
The weak motor buzzes high, the strong one rumbles low. Only Xbox controllers have motors in their triggers.
This browser can't make this controller vibrate.
