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 ...

With four independent 24-bit integrated electronics piezoelectric sensor inputs, the DT9837A is a high-performance USB module for sound and vibration analysis. The sensor inputs are synchronized with ...

Four 24-bit IEPE (ICP) sensor inputs synchronize with a tachometer input to provide data streams that are matched in time for field or laboratory use. A readback channel from the analog output ...

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 ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...
