Story

The Video

(its mainly for entertainment but I do explain a bit)

SO..

The idea was for comedic purpose but for those interested on how this build was made. Id say the build is very easy the only unique I did was add the handle from a small flashlight to give a narrow sight instead of a wider view(shown in video) that a PIR sensor usually gives. All powered by a portable charger.

Some advice do not buy mp3 modules off amazon or bang good just get it off the actual website. Learn from my mistakes.

Same schematics I used just a different speaker

(not my original)

Code

Talking Toliet

you can move around the sensor output and make sure to change audio files to mp3 or wav

#include <DFPlayerMini_Fast.h>


#if !defined(UBRR1H)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
#endif

DFPlayerMini_Fast myMP3;


int PIRPin = 2;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status



//
void setup () {
  Serial.begin(115200);
  mySerial.begin(9600);
  myMP3.begin(mySerial);
  
#if !defined(UBRR1H)
  mySerial.begin(9600);
  myMP3.begin(mySerial);
  
#else
  Serial.begin(9600);
  myMP3.begin(Serial1);
#endif
  Serial.println("Volume set");
  myMP3.volume(20);
  
  
 


                                                                    

 pinMode(PIRPin, INPUT);     // declare sensor as input
}


//
void loop () 



{
                   
    
  val = digitalRead(PIRPin);  // read input value
  if (val == HIGH) {            // check if the input is HIGH       



  if (pirState == LOW) {
      // we have just turned on
      Serial.println("Motion detected!");
      // We only want to print on the output change, not state
      pirState = HIGH;
      Serial.println("Playing that good shit ");
      delay(5000);
      myMP3.play(1);
      
 

}
} else {


if (pirState == HIGH){
      // we have just turned of
      Serial.println("Motion ended!");
      // We only want to print on the output change, not state
      pirState = LOW;
        
        
 
       
}
}
