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 ...

This project demonstrates a clap/sound-controlled smart switch using an Arduino, a microphone sensor, and a relay module. When the sensor detects a clap or loud sound, the Arduino toggles the relay ...

This project is a sound-controlled LED system built using a microphone sound sensor module and an Arduino. The system detects clap sounds and changes LED states based on the number of detected sound ...
