The sound sensor detects clapping or any loud sound, and sends a digital signal (HIGH) to the Arduino.Based on this signal: The Arduino turns ON the motor and LED.; After a few seconds, the Arduino ...

After I graduated I decided to implement a music visualizer at home using a led strip, Arduino board, and a sound detector. I used Arduino Nano and a Sparkfun sound detector. The sound sensor takes ...

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 ...

Lucía Garbo has created an Arduino powered noise pollution monitor, powered by an Arduino Mega micro-controller and housed in a 3D printed case. Other components include a SparkFun Sound Detector ...

As Arduino projects go, it isn’t very sophisticated. The circuit contains a sound detection module and an optoisolator. The code would easily fit on a piece of notebook paper.

The Arduino Sensor Kit comes as a standalone kit for only €23.00 or $23.00, or can be purchased with the Arduino UNO Rev3 board as a great value bundle for €38.70 or $38.70.

In a third stage, we can make the system portable by using a bare ATmega328, flashed with an Arduino bootloader, connected to the sensor. Powered from a battery as long as a button is pressed, the ...

Based on Arduino, a security system model is presented in this paper. Knock pattern is produced with the construction of piezo sensor and Arduino series board. The Knock detector is a distinctive way ...
