Tutorial: How to use ISD1820 Voice Sound Recording Module

The ISD1820 is an audio module for Arduino that allows recording and playing back voice messages. Ideal for interactive projects such as home alarms or voice guidance.

What you need

• Arduino
• microphone
• USB power supply

Steps

1. Connect the GND, VCC, and SPK pins of the ISD1820 module to the corresponding Arduino power supply.
2. Connect the microphone to the MIC input of the ISD1820 module.
3. Download the ISD1820 library for Arduino from the official website or GitHub.
4. Open a new sketch in Arduino IDE and include the installed library.
5. Insert the provided code in the tutorial, making sure to correctly configure the ISD1820 module pins.
6. Save the sketch as ‘ISD1820_Example’ in Arduino IDE.
7. Upload the sketch to your Arduino connected to the computer.
8. Press the PLAY button on the card to listen to the recording.

Example code

// Includi la libreria ISD1820
#include <ISD1820.h>

// Definisci i pin del modulo ISD1820
#define ISD1820_RESET_PIN 9
#define ISD1820_RECORD_PIN 10
#define ISD1820_PLAYBACK_PIN 11

ISD1820 isd;

void setup() {
 // Inizializza i pin del modulo ISD1820 come uscita
 pinMode(ISD1820_RESET_PIN, OUTPUT);
 pinMode(ISD1820_RECORD_PIN, OUTPUT);
 pinMode(ISD1820_PLAYBACK_PIN, OUTPUT);
}

void loop() {
 // Inizia la registrazione premendo il pulsante RECORD sulla scheda ISD1820
 isd.startRecording();
 delay(5000); // Registra per 5 secondi
 isd.stopRecording();
 
 // Riproduci il messaggio registrato premendo PLAY sul modulo
 isd.playMessage();
}

Mini project

Create a voice alarm that records and plays a warning message when triggered by a motion sensor.
