Example code

/* Esempio di codice per stabilire una connessione Bluetooth con XH-A158 */
#include <SoftwareSerial.h>

SoftwareSerial BTSerial(10, 11); // RX | TX

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

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

Mini project

Create a home alarm system with a microphone and a speaker connected to the XH-A158 module. The system sends an audio alarm when noise is detected.

Common mistakes

• Setting the power too high and damaging the power supply or the speaker
• Do not check Bluetooth connectivity before connecting the speaker
• Do not configure volume and other settings correctly
• Do not verify the compatibility of the microcontroller with the module

Recommended accessories

• External speaker
• Microphone
• 18650 battery
