Gamepad Test
Digital buttons, analog stick dead zones, trigger range and rumble motors (Gamepad API).
Connect your controller via USB or Bluetooth, then press any button on it to wake the page up.
Gamepad tests
Why this tester
Visual feedback
A true-to-scale Xbox button map — every press lights up on screen, so dead buttons are obvious at a glance.
Stick & trigger precision
Beyond on/off: live X/Y axis readouts expose stick drift, and the analog triggers (LT/RT) show depth on 0-1 bars.
Driver-free, works with everything
Built on the HTML5 Gamepad API. Xbox, PlayStation, Switch Pro and third-party pads — plug in via USB or Bluetooth and test.
How to start testing
- 01 · Connect the device
Plug the controller in via USB-C / Micro-USB or pair it over Bluetooth, and make sure the system recognizes it.
- 02 · Press a button (required)
For privacy/anti-fingerprinting reasons, browsers only expose gamepad data after you physically press any button on the pad.
- 03 · Test against the screen
Follow the on-screen controller: press every button, circle both sticks and pull both triggers, confirming the animation mirrors your input.
Controller terms explained
- Deadzone
- A small ignored region around the stick center, so tiny physical offsets do not move your view in game.
- Stick drift
- Worn or dusty potentiometers keep sending movement signals even when you are not touching the stick — the classic "character walks by itself".
- Linear (analog) trigger
- Unlike a plain on/off button, LT/RT read how far you pull, outputting 0.0 to 1.0 — essential for racing games.
- Hall effect sticks
- Sticks that sense position with magnetic fields instead of resistive film. No physical wear, so they effectively never drift.
Use cases
Second-hand check
Just got a used pad? Test stick drift and sticky buttons before the return window closes.
Emulator setup
Confirm the pad actually talks to your PC before mapping buttons in Yuzu / Ryujinx / RPCS3.
In-game gremlins
Cannot parry in Sekiro? Test the bumper — is it your finger speed or a dead micro switch?
Trigger travel check
Throttle feels short in Forza? Watch the trigger bar and see whether a full pull outputs the full 1.0.
Troubleshooting guide
Charges but never connects
Most likely a charge-only cable with no data lines. Swap in a known data USB-C / Micro-USB cable.
Drift without replacing sticks
WD-40 precision electronics cleaner (not the rust version) sprayed into the stick base, worked around, then dried, fixes most dust drift temporarily.
High Bluetooth latency
A loose antenna or a crowded 2.4 GHz band (headsets, other pads) adds lag. A dedicated 2.4 GHz dongle is the most stable option.
Buttons scrambled in Steam
Fine here but wrong in game? Steam → Settings → Controller, and enable configuration support for your pad type.
Frequently asked questions
My pad is plugged in — why does the page say "no gamepad detected"?
First, you must press any button on the controller while the page is open to activate the Gamepad API. Second, use an up-to-date Chromium browser (Chrome / Edge). Third, PS4/PS5 pads sometimes need DS4Windows to appear as an Xbox pad.
The stick dot does not return to center — is it broken?
A tiny offset is normal tolerance that in-game deadzones hide. A large offset that never re-centers is classic stick drift — the stick is worn out.
Can I test the rumble motors?
Browser security limits prevent web pages from triggering vibration in most browsers. Verify rumble in Steam Big Picture mode or in a game.
Why are my Switch Pro buttons swapped?
Not on this page. Browsers report face buttons by physical position (button 0 is the bottom key), which on a Nintendo pad is printed B. The Switch view draws the real Joy-Con layout — A right, B bottom, X top, Y left — and aligns indices by position, so the letter that lights up always matches what is printed on your pad.
A button double-fires or sticks — what now?
That is usually worn conductive rubber or sugary drink residue. Clean with high-purity alcohol or replace the rubber pad.
Gamepad basics
Types & connection
- Standard dual-stick (Xbox / PS layout): twin sticks + D-pad + shoulder keys — the universal shape.
- Pro / esports pads: add back buttons and swappable stick modules for precise, competitive play.
- Arcade sticks: lever + button array, built for fighting games.
- Wired / 2.4G / Bluetooth: wired is lowest latency, 2.4G is close, Bluetooth wins on device compatibility.
Core metrics
- Input lag: the time from press to signal — lower feels more responsive.
- Polling rate: how often the pad reports its state — higher = finer feedback.
- Inside: the main chip handles input, the stick potentiometer ages over time, and the rumble motor adds feedback.
Ideal specs often drop in real wireless use — measure actual input lag, response and stick accuracy with the tester.
Sticks & triggers
Stick technology
- Potentiometer sticks: measure position by resistance — cheap and mainstream, but can develop "drift" as they wear.
- Hall-effect sticks: sense position through magnetic fields — no mechanical wear, essentially no drift ever.
- Drift shows up as movement or camera motion while idle; in-game deadzones can mask small offsets.
Buttons & triggers
- Microswitch quality decides click feel and lifespan.
- Adaptive triggers (e.g. PS5 DualSense) simulate different resistance in-game.
- Trigger travel lock shortens the pull for faster repeat presses in shooters.
- Back buttons and hot-swap stick modules expand control and make fixes easy.
Connection & compatibility
Connection protocols
- Wired USB: lowest latency and no battery worry — the comp pick.
- 2.4G wireless: a dedicated dongle, latency close to wired, cable-free.
- Bluetooth: the most compatible (phone / tablet / PC / some consoles) but usually higher latency.
Platform compatibility
- Console-native (Xbox, PS), PC pads and cross-platform pads all differ in protocol and driver.
- Check interface protocol and driver support — "connects but some buttons don't work" is common.
- Testing every button and axis before mapping in emulators saves setup pain.
Features & ergonomics
Ergonomics
- Grip curve and anti-slip texture decide comfort in long sessions.
- Trigger travel or adaptive resistance can be tuned per game type.
- Pick a shape and weight that matches your hand and play style.
Extras
- Rumble: linear motors feel finer and more layered than old rotor motors.
- Programmable back buttons: trigger near actions without moving your thumbs.
- Hot-swap stick modules and remapping software are the rising "custom pad" scene.
Using & maintaining your gamepad
Quick fault checks
- Stick drift (idle character/camera motion): worn potentiometer or dust inside.
- Dead / slow buttons: aging microswitches or bad contact.
- Wireless dropouts: interference, low battery or receiver too far away.
- Test each button, stick travel and center point first — pin it down before opening anything.
Daily care
- Brush dust out of stick gaps and around buttons regularly.
- Avoid storing the sticks fully deflected (e.g. crushed under weight).
- Don't leave wireless batteries fully drained for long; cycle them now and then.
- For light drift, recalibrate the deadzone in the OS or software before replacing modules.
Buying guide
Use cases
- Casual / console: the official first-party pad is enough for most.
- Competitive: wired or 2.4G with low latency, plus back buttons.
- Multi-platform: a cross-platform pad with one-key connection switching.
Sticks & connection
- Prefer Hall-effect sticks if budget allows — no future drift.
- For old-school pots, check module replacement and warranty.
- Wired / 2.4G for low latency; Bluetooth for portability and devices.
Verify what you buy
- Test real button response, centered stick travel and any drift signal first.
- Do it within the warranty window to catch QC issues and swap early.
- Calibrate deadzones in-game or in the system to match real behavior.
Brands & budget
- International: Microsoft, Sony, Logitech — solid first-party build and ecosystem.
- Value Chinese: 8BitDo, Flydigi, Zhengdian — cross-platform and price/performance.
- Enthusiast: GuliKit, Scuf — Hall-effect modules and pro programmable pads.
- Budget from casual to flagship — the leap is sticks, adaptive triggers and modular design.
