I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter ...

Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

This post describes the preliminary results of a small Hall-Sensor module. This is widely known as KY-024 module. The KY-024 sensor module I got from an online retailer is inexpensive, and the ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...

For building complex, synchronized systems for high-channel-count sound/vibration applications, the PXI-4498 and PXI-4496 dynamic signal acquisition (DSA) modules offer 16 simultaneous, 24-bit analog ...
