Example code

void setup() {
  Serial.begin(9600);
  // Inizializza il display LCD
}
void loop() {
  // Leggi i dati dal misuratore di potenza
  // Verifica sul datasheet per i dettagli di lettura specifici
  Serial.print("Corrente:");
  Serial.print(current);
  Serial.print(" V");
  Serial.print(" Tensione:");
  Serial.print(voltage);
  Serial.print(" V");
  Serial.print(" Potenza:");
  Serial.print(power);
  Serial.println(" W");
}
