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 ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

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 ...
