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 ...

Sound direction detection is a fascinating concept in robotics and automation. It allows a device to "hear" and determine the direction of a sound. This concept has numerous applications, including ...

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 ...

This project is an interactive Arduino-based piano that plays musical notes and a song stored on an SD card. It also includes a sound spectrum visualizer using an LED matrix, which reacts to the audio ...
