Unity to Arduino

Projects Programming

Hello,
I have some problems to get a serial connection between Unity and my Arduino. When I use Serial.read(); the connection from Unity to my Arduino works fine but I'm only able to send one byte. In the code below happens the following. When I send a 0 to the Arduino (via the Serial Monitor) I get a 48. When I send a 10 I get a 49 and a 48.
When I use Serial.parseInt(); my Arduino works fine (it responds a 10 when I send a 10) but I get the IOException error on Unity.
Is there any way to read data like parseInt but use Serial.read(); so I can connect to Unity?

I count not find any solution in this forum but I'm not really familiar with Arduino, so maybe I already found something but wasn't able to understand it.

#include <Servo.h>

Servo myservo;
int input;
int state;
void setup()
{
  myservo.attach(9);
  Serial.begin(57600);
  myservo.write(75);
  delay(10);
}

void loop() {


  if (Serial.available()>0) {
    input = Serial.read();
    myservo.write(input);
    Serial.println(input);
    delay (1);
    }
 }

Greetings

I found a way to fix it... I'm not sure whether this is the best way or not, but it works for me.

#include <Servo.h>

Servo myservo;
int input;
int state;
String readString;
String emptyString;

void setup()
{
  myservo.attach(9);
  Serial.begin(57600);
  myservo.write(75);
  delay(10);
}

void loop() {
  
  while (Serial.available()) {
    delay(3);  //delay to allow buffer to fill 
    if (Serial.available() >0) {
      char c = Serial.read();  //gets one byte from serial buffer
      readString += c; //makes the string readString
    } 
  }

  if (readString.length() >0) {
      Serial.println(readString); //see what was received
      input = readString.toInt(); //get the first four characters
      myservo.write(input);
      readString = emptyString;
}
}
