Welcome to the Arduino Sound-Activated Projects repository! This repository contains Arduino sketches for creating interactive projects using sound sensors and relay modules. These projects are ...

This system is a flashing LED TV backlight that contains a sensitive mic sensor that allows the LED lights to dance to the music tempo. The device uses a mic sensor as an input as it receives the ...

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 ...

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 ...
