Mar 27, 2024 · In this project, I will talk about one of the most commonly used Voice Recorder Modules in the electronics hobbyist community, the ISD 1820 Voice Recorder Module and show you how to control it with the help of Arduino.

This module is easy to use which you could direct control by push button on board or by Microcontroller such as Arduino, STM32, ChipKit etc. From these, you can easy control record , playback and repeat and so on.

Feb 9, 2025 · Arduino ISD1820 Voice Recorder & Playback Module- In this tutorial, you will learn how to interface the ISD1820 Voice Recorder and Playback Module with Arduino and play different recorded messages using different Sensors.

To use the functions of the library first we must create an instance of class ISD1820 called with any name (in the program example is called module) and in the parameters you must specify the pins connected to the module REC , PLAY_E , PLAY_L.

This circuit features an Arduino UNO microcontroller interfaced with an ISD 1820 voice recording and playback module and an HC-SR04 ultrasonic sensor. The Arduino controls the playback of the ISD 1820 module and reads distance measurements from the HC-SR04 sensor.

Apr 15, 2025 · The ISD1820 is a small ready-made module which can record human voice for short time and then play it back. It is based on the ISD1820 IC which is a voice record and playback chip.

Jun 12, 2018 · The Voice Record Module is based on the ISD1820 chip, a multiple‐message record/playback device. It can offer true single‐chip voice recording, non-volatile storage, and playback capability for 8 to 20 seconds.

Jan 5, 2022 · How to operate the ISD1820 recorder module? Connect a small 8Ω speaker at the output end of the module, that is, across the SP + and SP- pins. Press the record button (REC) on the module, and the module starts recording. Keep pressing the button until the complete message is recorded (for example, about 10 seconds).

Feb 4, 2025 · The most commonly used voice recorder used in this interfacing is the ISD 1820 voice recorder module which shows how to control it using an Arduino board. The ISD1820 voice recorder module stores the messages in its non-volatile memory from 8 Sec to 20 Sec lengths.

Jul 13, 2018 · Voice Record Module is base on ISD1820, which a multiple‐message record/playback device. It can offers true single‐chip voice recording, no‐volatile storage, and playback capability for 8 to 20 seconds. The sample is 3.2k and the total 20s for the Recorder.
