Tutorial: How to use the LD3320 Voice Module

The LD3320 voice module is ideal for projects that require voice interaction. Useful for beginners and intermediates, it allows you to add audio features to your projects.

What you need

• Arduino or compatible
• Power cable
• 10kΩ resistor
• Microphone (optional)
• Arduino breadboard
• Audio setup (for testing)

Steps

1. 1. Connect the module to the Arduino via digital pins and GND.
2. 2. Connect the 10kΩ resistor between VCC and GND.
3. 3. Connect the microphone (if used) to the audio input pin.
4. 4. Power the module with a USB cable or a battery.
5. 5. Upload the code to Arduino.
6. 6. Check the serial communication to verify the connection.
7. 7. Try speaking into the microphone and verify the voice response.
8. 8. Adapt the code to your specific needs.

Example code

```cpp
#include <SoftwareSerial.h>

SoftwareSerial vocale(10, 11); // RX, TX

void setup() {
  Serial.begin(9600);
  vocale.begin(9600);
}

void loop() {
  if (vocale.available()) {
    Serial.write(vocale.read());
  }
}
```
