In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

The bizarre properties of discrete time crystals could be harnessed to detect extremely subtle oscillations of magnetic ...

Named after the Italian word for "21," Ventuno Q is Qualcomm's first attempt to soothe the wary Arduino community. The UK chip designer acquired the Italian ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

After acquiring Arduino last October Qualcomm has announced a new single-board computer called the Ventuno Q. Pricing and availability aren’t known, but it will be powered by a Dragonwing IQ8 ...

Regular readers will know that Hackaday generally steers clear of active crowdfunding campaigns. But occasionally we do run across a project that’s unique enough that we feel compelled to dust off our ...

A basic building block is often the key to completing an analog signal path in various applications, such as automated test equipment.

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...
