Tutorial: How to use Micro LD3320

The Micro LD3320 is a non-specific voice recognition module that allows controlling devices with voice commands. Useful for electronic and maker projects.

What you need

• Micro LD3320
• Arduino
• 10kΩ Resistor
• 5V Power Cable
• Ground Cable
• Microphone

Steps

1. 1. Install the module on an Arduino using a shield.
2. 2. Connect the microphone to the VCC and GND pins of the module.
3. 3. Connect a 10kΩ resistor between VCC and GND of the module.
4. 4. Connect VCC of the module to the 5V of Arduino.
5. 5. Connect GND of the module to the GND of Arduino.
6. 6. Load the provided Arduino code.
7. 7. Try speaking to the predefined voice commands.
8. 8. Check the datasheet for further settings.

Example code

```cpp
#include <LD3320.h>

LD3320 voiceControl;

void setup() {
  voiceControl.begin();
}

void loop() {
  if (voiceControl.isCommand()) {
    Serial.println(voiceControl.getLastCommand());
  }
}
```

Mini project

Create a voice switch to turn on/off an LED.

Common mistakes

• Do not connect the microphone correctly.
• Use a resistor other than 10kΩ.
• Do not check the settings on the datasheet.
• Omit the verification of the Arduino code.

Recommended accessories

• LED and current limiting resistor
• 100Ω resistor
• Ground wire
• High-quality microphone
