Arduino Halloween Project 2021

The Code:

The code is fairly straight forward, and if you have read the two guides mentioned above you will know exactly what is going on.

//Include Libraries
#include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"

SoftwareSerial mySoftwareSerial(10,11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;

//Pin To Read PIR Sensor Data
int pirPin = 7;

//Variable To Store PIR Sensor Data
int pirValue;

// Set Duration Sound Effects Will Loop For
int soundLoop = 20000;

// Set Volume Level 0-30
int volLvl = 15;

void setup() {
  Serial.begin(9600);
  mySoftwareSerial.begin(9600);
  myDFPlayer.begin(mySoftwareSerial);
  myDFPlayer.volume(volLvl);
  pinMode(pirPin,INPUT);

  //Add Delay To Stabilize PIR Sensor
  Serial.println("10 Second Wait While Sensor Stabilizes");
  delay(10000);
}

void loop() {
  // Read PIR Pin
  pirValue = digitalRead(pirPin);
  
  // Set Trigger Condition
  if (pirValue == 1){
    Serial.println("Motion Detected");    
    myDFPlayer.enableLoopAll(); // Uncomment to Loop All
    //myDFPlayer.randomAll(); // Uncomment to Randomize   
    delay(soundLoop);           
  }else{
    Serial.println("No Motion");
  }
  myDFPlayer.disableLoopAll();  
  delay(1000);
}
