Welcome to the Arduino Sound-Activated Projects repository! This repository contains Arduino sketches for creating interactive projects using sound sensors and relay modules. These projects are ...

What are the types of sound sensors? There are different types of microphones that are known as sound sensors like dynamic, condenser, ribbon, carbon, etc. What are the advantages of a sound sensor?

Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like ...

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 ...

The KY-038 sound sensor pinout has 4 pins: VCC, GND, Digital Out, and Analog Out. We can either use the AO pin as an output for analog reading or the DO pin as an output for digital readout. The Sound ...
