The human ear can decipher the loudness of a sound. Also, given two sound signals of different intensities, it can distinguish the differences. But is there a device that can do the same? If you are ...

The Arduino Mega interfaces with a microphone sound sensor module to detect sound levels and frequencies, ideal for audio monitoring, sound-activated systems, and noise measurement applications in ...

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 ...

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 ...
