A robust and easy‑to‑use Arduino library for controlling the DY-SVAudio5W Audio Module using serial communication.
This library provides a clean, object‑oriented interface for sending audio commands, controlling playback, adjusting volume, and querying device status.

• Supports:
  • Play / Pause / Stop\
  • Volume Up / Down / Set Volume\
  • Mute / Unmute\
  • File & Folder based playback\
  • Track selection\
  • Querying module status\
  • Equalizer\
  • Looping Modes\
• Non-blocking and intuitive command structure\
• Compatibility Arduino UNO(Tested), Nano(Tested), ESP32(Not Tested), ESP8266(Not Tested), Raspberry Pi(Not Tested) and more

1. Go to Sketch → Include Library → Add .ZIP Library...\
2. Select the downloaded DYSVAudio5W.zip\
3. Done! The library will now appear under File → Examples → DYSVAudio5W

The Power pins of DYSV module should connect to 5V and GND
TX and RX of DYSV should connect to Software Serial(RX and TX) respectively
TX of DYSV -> RX of MCU
RX of DYSV -> TX of MCU

#include <SoftwareSerial.h>
#include "DYSVAudio5W.h"

//Connecting to Arduino Uno pins
int RX_PIN = 10;
int TX_PIN = 11;

SoftwareSerial Serial1(RX_PIN, TX_PIN); //Software serial is used to send UART commands to the module
DYSVAudio5W player(Serial1, 9600, Serial); //Init

void setup() {
  Serial.begin(9600); //Serial comm to computer
  Serial1.begin(9600); //Serial comm to the audio module
  player.begin();
}

void loop() {
  player.startPlayback(); //Start playing the songs
}

• Module requires valid FAT32 SD card
• Volume range: 0 to 30
• Commands are non-blocking but some modules require a short delay(Check Examples)
