Hola, tengo un sketch de processing que recibe data de un sensor (on/off) conectado a un arduino. El tema es que los datos enviados de arduino son strings y necesito que sean int. Estoy intentando convertirlos pero me tira error, alguien sabe porque?
Adjunto una imagen del error
codigo arduino
// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
Serial.begin(9600);
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
Serial.println("1.");
delay(250);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
Serial.println("0.");
delay(250);
}
// Serial.println();
// //Serial.print("el boton esta en: ");
// Serial.print(buttonState);
//delay(400);
}
