ISD1820 Voice Recorder module


৳ 345.00

The ISD1820 Voice Recorder Module is based on the ISD1820 IC, which is a single chip Voice recorder IC for single message record and playback. I am not sure about the availability of only the IC but it is frequently found in the module with all the necessary components and circuitry.

A major feature of the ISD1820 Voice Recorder Module is that is can store the messages in its non-volatile memory and can be configured to store messages of length between 8 Seconds to 20 Seconds.

The ISD1820 Voice Recorder Module used in this project is shown below. As you can see, there are a lot of components on the board that help the ISD1820 IC in recording and playback.

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.

Sample code

int rec=2;
int play=3;
int sensor=4;
int led=13;

void setup()
{
pinMode(rec,OUTPUT);
pinMode(play,OUTPUT);
pinMode(led,OUTPUT);
pinMode(sensor,INPUT);

digitalWrite(rec,LOW);
digitalWrite(play,LOW);
digitalWrite(led,LOW);
if(digitalRead(sensor))
{
while(digitalRead(sensor));
}
}

void loop()
{

if(digitalRead(sensor))
{
digitalWrite(led,HIGH);
digitalWrite(rec,HIGH);
delay(5000);
digitalWrite(led,LOW);
digitalWrite(rec,LOW);
delay(1000);
digitalWrite(play,HIGH);
delay(6000);
digitalWrite(play,LOW);
while(digitalRead(sensor));
}
