Example code

// Codice Arduino minimo
// Collega un relé alla scheda TPA3116D2 se si utilizza il controllo remoto.
int relayPin = 7; // Pin del relé collegato all'amplificatore
void setup() {
    pinMode(relayPin, OUTPUT);
}
void loop() {
    digitalWrite(relayPin, HIGH); // Accende l'amplificatore
    delay(5000); // Aspetta 5 secondi
    digitalWrite(relayPin, LOW); // Spegne l'amplificatore
}
