Story

Ā 

In this Project, we will learn, how we can make security alarm by using PIR sensor and DF player Mini. This system detect motion in room and play audio, Security Alert ! some one entered in the room. You can use this as welcome audio player for guests.

Ā 

For making this project, I am using:-

Ā 

-Arduino UNO

Ā 

-DF player Mini

Ā 

-Alarm Speaker

Ā 

-SD Card

Ā 

-PIR sensor (Motion sensor)

Ā 

-5 Volt Audio Amplifier

CODE
#include "DFRobotDFPlayerMini.h"
const int buttonPin = 7;
int buttonState = 0;
DFRobotDFPlayerMini player;

void setup() {
  
pinMode(buttonPin, INPUT);
  // Init USB serial port for debugging
  Serial.begin(9600);
  // Init serial port for DFPlayer Mini
  //softwareSerial.begin(9600);

  // Start communication with DFPlayer Mini
  if (player.begin(Serial)) {
   Serial.println("OK");

    // Set volume to maximum (0 to 30).
    player.volume(30);
    // Play the first MP3 file on the SD card
    //player.play(1);
  } else {
    Serial.println("Connecting to DFPlayer Mini failed!");
  }
}

void loop() {
  buttonState = digitalRead(buttonPin);
   if (buttonState == HIGH) {
    player.play(1);
  }
}
