As answered by people managing Timer Tab and HardwareTestingPro.
HardwareTestingPro's answer:
HardwareTestingPro combines 77+ hardware diagnostic tools into a single browser-based platform - no installs, no sign-ups, and no ads getting in the way. From keyboard and mouse testing to monitor, mic, camera, and gamepad checks, everything runs instantly using your browser's built-in APIs, giving accurate real-time feedback in seconds.
HardwareTestingPro's answer:
Unlike many hardware testing tools that require downloads or account creation, HardwareTestingPro works entirely in the browser with zero friction. It offers a wider range of tools (77+) in one place, a clean and fast interface, and results you can trust without worrying about privacy or bloatware.
HardwareTestingPro's answer:
Gamers checking peripherals before matches, IT professionals troubleshooting hardware issues, remote workers setting up new equipment, and everyday users who want a quick way to confirm their keyboard, mouse, webcam, or mic is working properly.
HardwareTestingPro's answer:
HardwareTestingPro was built out of frustration with clunky, ad-heavy hardware testing websites that required downloads for simple checks. The goal was to create a fast, free, no-nonsense tool that works instantly for anyone who needs to verify their hardware is functioning correctly.
HardwareTestingPro's answer:
HardwareTestingPro is built using core web technologies - HTML, CSS, and vanilla JavaScript - along with native browser APIs (such as the Web Audio API, MediaDevices API, and Gamepad API) to power the real-time hardware testing tools directly in the browser, without relying on heavy frameworks or backend dependencies.

Timer-tab.com is also great, though you can't embed it in a PPT (at least not easily) - you can set any amount of time, the time will fit your window (great if you need to split the screen), and you can set the background and alarm... Source: about 4 years ago
