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 ...

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 ...

Presented here is an Arduino-based noise/sound level monitor that displays sound levels in decibels (dB) and corresponding voltage levels on an LCD. A noise monitoring system is used in many ...

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 ...

The Circuit diagram of smart whistle counter is shown in figure-1, It is based on Arduino Mega 2560 board. LM393 based sound sensor module is used for detection of sound of whistle. It operates at 5V ...
