X350 USB Sound Audio Board

Description

What it is

The X350 USB audio card is a device that allows for audio signal acquisition and amplification. This component is designed to be used in various types of projects, especially those based on Arduino.

Features

• Multifunction audio card with audio input and integrated amplifier
• Direct USB connection to a computer for configuration or debugging

What it is for

The X350 USB Sound card is ideal for projects that require audio signal acquisition and processing. You can use it to create simple audio recording systems by connecting a microphone to the card and reading the sound values with an Arduino. The acquired data can then be saved to an SD card.

Tutorial: How to use X350 USB Sound

The X350 USB Sound is a multi-functional audio card ideal for projects requiring audio input and amplification. Useful for beginners and intermediates, it supports direct USB connection to a computer.

What you need

• X350 USB Sound
• Arduino or compatible microcontroller
• Microphones or audio sources
• 5V Power Supply (from Arduino or another source)

Steps

1. 1. Connect the 5V power supply to the X350 USB Sound.
2. 2. Connect the microcontroller (e.g., Arduino) to the X350 USB Sound via the power and reset pins.
3. 3. Connect a microphone or audio source to the audio input pin of the X350 USB Sound.
4. 4. Connect the audio output pins to your project or audio system.
5. 5. Upload the code to Arduino.
6. 6. Check that the microcontroller correctly detects the audio input.
7. 7. Verify the audio power specifications in the datasheet.
8. 8. Test the audio amplification.

Example code

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

void loop() {
  int soundLevel = analogRead(A0);
  Serial.println(soundLevel);
}
```

Mini project

Create a simple audio recording system. Connect a microphone to the X350 USB Sound, then read the sound values with an Arduino and save the data on an SD card.

Common mistakes
