- 0002.mp3 → "User not recognized"
---
🔌 DFPlayer Mini Wiring with Arduino:
| DFPlayer Pin | Ard
| VCC | 5V |
| GND | GND |
| TX | Pin 10 |
| RX | Pin 9 |
| SPK_1 & SPK_2| Speaker
📜 Arduino Code Example:
cpp
#include <SoftwareSerial.h>
#include <DFRobotDFPlayerMi
SoftwareSerial mySerial(10, 9); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
void setup() {
mySerial.begin(9600);
Serial.begin(9600);
if (!myDFPlayer.begin(mySerial)) {
Serial.println("Unable to begin DFPlayer Mini")
while (true);
}
myDFPlayer.volume(25); // Volume: 0 to 30
myDFPlayer.play(1); // Play 0001.mp3
}
void loop() {
// Fingerprint detect hone par
// myDFPlayer.play(fileNumber);
}
🧠 Logic:
- جب Fingerprint match ہو:
- Arduino کو file number بتاؤ
- DFPlayer وہ mp3 file play کرے گا
---
🧪 Example:
- User ID = 3
- 0003.mp3 plays → "Welcome User 3" (in selected language)
---

from gtts import gTTS
import os
r = sr.Recognizer()
translator = Translator()
with sr.Microphone() as source:
print("Speak now...")
audio = r.listen(source)
text = r.recognize_google(audio, language="ur") # User spoke in Urdu
print("You said:", text)
translated = translator.translate(text, dest='en') # Translate to English
print("Translated:", translated.text)
tts = gTTS(translated.text, lang='en')
tts.save("output.mp3")
os.system("start output.mp3")
```
