An Arduino-based system that detects loud sounds (like a baby's cry) and alerts the user via an LED and LCD screen. This project was built as part of an academic electronics module at ENSTTIC. It ...

The Noise Level Detector is an Arduino-based project designed to measure and display the intensity of noise using a sound sensor module and a 16x2 LCD display. It provides a simple and cost-effective ...

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 ...
