Upload the following code to your Arduino UNO: pinMode(micPin, INPUT); // Configures the sound sensor pin as input pinMode(ledPin, OUTPUT); // Configures the LED pin as output // Read the sound sensor value micValue = digitalRead(micPin); // Check if the sound. Upload the following code to your Arduino UNO: pinMode(micPin, INPUT); // Configures the sound sensor pin as input pinMode(ledPin, OUTPUT); // Configures the LED pin as output // Read the sound sensor value micValue = digitalRead(micPin); // Check if the sound. In this tutorial, we are going to learn how to use Arduino and sound sensor to detect the sound. In detail, we will learn: Afterward, you can tweak the code to make it activate an LED or a light (via a relay) when it detects sound, or even make a servo motor rotate. The module provides two outputs: a digital output (LOW/HIGH) and an analog output. 2 – English Thank you for choosing Talking Products Ltd. We hope you enjoy using this sound module and we are here for support if you need any assistance. Please see contact details overleaf. Please read these instructions carefully and retain. With the help of two Arduino sketches, we will be able to create a sound detection project whereby a clap sound will toggle the state of a LED connected with the Arduino board. Connect the sound sensor's DO (Digital. Light Sensor Sound Module is ideal for musical boxes, interactive display units, marketing materials with voice, special gifts, school projects, talking invitations, etc. Sound module can be recorded from videos, sound files (any format), voice recordings, phone messages, etc Light Sensor Sound.
