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 ...

When a clap sound is detected, the relay toggles the bulb ON/OFF. Useful for smart home and assistive tech. Clap sound is detected by the sound sensor. Arduino reads the signal. Relay switches the ...

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 ...

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 ...
