ISD 1820 Voice Recording Module (ISD1820) [S082]



https://www.youtube.com/watch?v=cj9h0Bzwcok


*GitHub : 


* Specs

ISD1820 Voice Recording Module is another very interesting stuff. You don't need to prepare a speaker and a mic - both are included in this module! After connecting to the power, you can press REC to record a 10 second voice. Press PLAYE to play the complete voice once. Press and hold PLAYL it will play the voice and it stop when the button is released. It can also be controlled by Arduino. Combined with Laser Detector and Laser Module, you can make a doorbell, security system, and power-saving light along corridor for instance.

int Rec = 11;

int Play = 13;


void setup()

  pinMode(Rec, OUTPUT); 

  pinMode(Play, OUTPUT);


  lcd.init();  // initialize the lcd 

  lcd.backlight();

  lcd.print("start LCD2004");


  delay(1000);


  lcd.clear();

}


void loop()

{

  lcd.setCursor(0,0);

  lcd.print("S082:ISD1820 Module");


  digitalWrite(Rec, HIGH); // record 10sec

  lcd.setCursor(0,1);

  lcd.print("Rec: HIGH ");


  delay(10000);

  digitalWrite(Rec, LOW); // end record 

  lcd.setCursor(0,1);

  lcd.print("Rec: LOW  ");

  delay(5000);

FM Radio Receiver Module 87-108MHz with Serial Control [S222]



https://www.youtube.com/watch?v=CpoA0x5llbk


* Specs

Features

-adopt the advanced technology of DSP and FM modulation PLL to make sound more realistic, more stable performance,

long working hours without frequency offset.

-LCD display more intuitive and accurate, with very low power consumption and minimal noise interference.

-30 range digital volume adjustment, can be easily operated with keystrokes.

-Automatic memory data before the power failure.

-Automatically switched speaker and reciver output

-Adopt quartz crystal frequency stabilization, the temperature change is no longer receiving frequency drift.

-The professional audio DSP audio signal analysis and processing, automatic mute

no signal or weak when FM signal noise, get rid of traditional FM radio in the absence

of signal or weak signal when annoying rustling.
