Consulta sobre programacion (Consultation on programming)

Saludos a toda la comunidad, tengo una pequeña duda para hacerles, ya que soy nuevo en el tema, estamos armando junto a unos compañeros un proyecto de domotica para una muesta que se realizara dentro de poco, mi duda esta en esta parte de codigo que adjunto, a la hora de ingresar por puerto serial ya sea por teclado o por BT, "encender baño" o "apagar baño" el arduino no reconoce la opcion, pero si saco la letra "ñ" funciona correctamente. Uds tienen alguna sugerencia para poder seguir usando el comando ideal que seria "encender baño". Desde ya muchas gracias

Greetings to the whole community, I have a small question for you, since I'm new to the subject, am working together with some
companions of school a project home automation for an exposition that will be soon, my question is in this part of code that when entering by serial port either by keyboard or by BT, "encender baño" or "apagar baño" the arduino does not recognize the option, but if I remove the letter "ñ" works correctly. You have any suggestions to continue using the ideal command that would would "encender baño" and "apagar baño". From already thank you very much

char inChar;
String string="";
void setup() {
string.reserve(200);
pinMode(4,OUTPUT);
Serial.begin(9600);
}

void loop() {
  if (Serial.available()){
  inChar = Serial.read();
  string+=inChar;
    if (inChar=='.'){
      Serial.print("Lectura: ");
      Serial.println(string);
      if(string=="encender baño.")){
                digitalWrite(4,HIGH);
                Serial.print("luz de baño encendida");}
      if(string=="apagar baño"){
                digitalWrite(4,LOW);
               Serial.print("luz de baño apagada");}
      string="";}
    }
}

The Arduino understands characters whose ASCII code is in the range -128 to 127. Of course, there are none with negative values. What is the ASCII code for 'ñ'?

PaulS thank you for answering. the ASCII code for the letter ñ in arduino is 241

Then, according to what you tell me i will not be able write the letter ñ for this job? Excuse my ignorance

Excuse my ignorance

Ignorance is a problem only if no effort is made to correct it. That does not apply to you.
