Fig. 1: Circuit diagram of the noise level monitor. When sound is detected by the microphone in the sound sensor module, corresponding voltage and sound levels are displayed in dB on LCD1. Sound ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital ... Arduino ...

Arduino Soil Moisture Sensor Circuit – Connection Diagram. Now that we have a complete understanding of how a Soil Moisture sensor works, we can connect all the required wires to the Arduino UNO board ...

This project uses a sound sensor to control an LED with an Arduino. The LED lights up when the sound sensor detects noise above a certain threshold, making it a fun way to create sound-reactive ...

Mega 🔥 A simple home automation project using Arduino Mega, a sound sensor (KY-038), and a 5V relay module to control a 7W AC LED bulb with a clap. 🔧 Features: Clap to turn the light ON/OFF Uses a ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons. The goal here was to keep things as simple as ...

This circuit is brought to life by an Arduino sketch that first includes the wire.h library to provide low-level functions to communicate over the I 2 C lines. These functions are used right away in ...

This all-in-one kit provides an ideal platform for learning the basics of UNO programming and sensor interfacing, making it perfect for hands-on projects. The kit includes 18 essential items, ...
