This project uses a sound sensor to control an LED with an Arduino. The LED lights up when the sound sensor detects noise above a certain threshold, making it a fun way to create sound-reactive ...

This Arduino project controls the brightness of an LED based on input from an ultrasonic distance sensor and a sound sensor. The LED's brightness is dynamically adjusted according to the distance ...

The brilliant metallic blue wings of Morpho butterflies dazzle the eye. Branched nanostructures on the wings scatter light in complex ways to produce this characteristic iridescent hue. By harnessing ...

A new type of sound sensor system has been developed to predict the likelihood of a landslide. Thought to be the first system of its kind in the world, it works by measuring and analyzing the acoustic ...

[Tobe] has an intervalometer for his camera, but he wanted a device that could trigger the shutter using several different methods, not just time. He calls his creation the Megavallometer, which can ...
