3️⃣ How to Make a Sound-Playing Toy? (Step-by-Step Guide)

📌 Required Components:

✔️ DFPlayer Mini or ISD1820
✔️ Arduino Nano / ATtiny85
✔️ 8Ω 1W Speaker
✔️ Li-ion Battery (3.7V or 5V)
✔️ Push Button or Motion Sensor
✔️ Jumper Wires and Soldering Kit

🔧 Connections (Wiring Diagram)

1️⃣ Connect DFPlayer Mini to Arduino:

• VCC → 5V, GND → GND

• TX → Arduino RX, RX → Arduino TX

• Connect the speaker to DFPlayer's output

2️⃣ Add Push Button / Sensor:

• Audio plays when the button is pressed

3️⃣ Programming (Code Upload)

• Install DFPlayer Mini Library in Arduino IDE

• Write and upload the code to play audio

#include <SoftwareSerial.h>
#include <DFRobotDFPlayerMini.h>

SoftwareSerial mySoftwareSerial(10, 11);
DFRobotDFPlayerMini myDFPlayer;

void setup() {
  mySoftwareSerial.begin(9600);
  Serial.begin(115200);
  if (!myDFPlayer.begin(mySoftwareSerial)) {
    Serial.println("DFPlayer Mini not detected!");
    while (true);
  }
  myDFPlayer.volume(30);  // Set volume (0-30)
}

void loop() {
  if (digitalRead(2) == LOW) {  // If button is pressed  
    myDFPlayer.play(1);  // Play track 1  
    delay(2000);
  }
}
