help to use value from arduino in unity :)

hey there everyone, so here’s what i’m trying to do :
I have a arduino board with a gyroscope, i’m using it to retrieve the rotation and take it into unity. In unity i want to use the data to rotate a cube, based on the rotation from the arduino. the sad thing is that i have no idea how to use the data i’m receiving from the arduino :confused: anyone got an idea ? thx ^^

here is my arduino code :

#include<Wire.h>

const int MPU = 0x68;
int16_t AcX, AcY, AcZ, Tmp, GyX, GyY, GyZ;
long Ax, Ay, Az;
void setup() {
  Wire.begin();
  Wire.beginTransmission(MPU);
  Wire.write(0x6B);
  Wire.write(0);
  Wire.endTransmission(true);
  Serial.begin(9600);
}


void loop() {

  Wire.beginTransmission(MPU);
  Wire.write(0x3B);
  Wire.endTransmission(false);
  Wire.requestFrom(MPU, 12, true);
  AcX = Wire.read() << 8 | Wire.read();
  AcY = Wire.read() << 8 | Wire.read();
  AcZ = Wire.read() << 8 | Wire.read();
  GyX = Wire.read() << 8 | Wire.read();
  GyY = Wire.read() << 8 | Wire.read();
  GyZ = Wire.read() << 8 | Wire.read();

  //Serial.print("Accelerometer: ");
  //Serial.print("X = "); Serial.print(AcX);
  //Serial.print(" | Y = "); Serial.print(AcY);
  //Serial.print(" | Z = "); Serial.println(AcZ);

  //Serial.print("Gyroscope: ");
  //Serial.print("X = "); Serial.print(GyX);
  //Serial.print(" | Y = "); Serial.print(GyY);
  //Serial.print(" | Z = "); Serial.println(GyZ);
  //Serial.println(" ");

  //Ax += GyX;
  Ay += GyY + 20;
  //Az += GyZ;

  //Serial.print(Ax);
  //Serial.print(", ");
  Serial.print(Ay/8000.f *360.f);
  //Serial.print(", ");
  //Serial.print(Az);
  Serial.println("");

  delay(33);
}

and in unity i have this :

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO.Ports;

public class COMARDUINO : MonoBehaviour
{

    SerialPort arduinoport = new SerialPort("COM3", 9600);
    // Start is called before the first frame update
    void Start()
    {
        arduinoport.Open();
    }

    // Update is called once per frame
    void Update()
    {
        string arduinomsg = arduinoport.ReadLine();
        Debug.Log(arduinomsg);
    }
}

it work fine the debug log is showing me the data, but i don’t know how to use them :confused:

You’d need to use standard C# string parsing to take the string and convert it into numerical values. Since I have no idea what the numbers in those strings represent, I can’t tell you what to do with them specifically. But I’m going to guess you’ll either be calling Rotate, or setting the transform.rotation directly.
