Question by stevensu1838 · Feb 15, 2019 at 08:33 AM · arduinoserialportaccess denied

Need help with Arduino to Unity "IO:Exception Access is Denied",Need help with sending data from Arduino to Unity "IO:Exception Access is Denied"

Hello,

I seem to be having an issue with using an Arduino to control a cube objects within a scene. When I apply my code to in the scene I get the error in the Unity console"IO: Exception Access is Denied". Can any of you experts help me out? Thanks a million.

My C# code:

 using System.Collections;
 
 using System.Collections.Generic;
 
 using UnityEngine;
 
 using System.IO.Ports;
 
 public class MoveHand : MonoBehaviour {
 
 public float increment;
 
 SerialPort stream = new SerialPort("COM5", 9600);
 
 // Use this for initialization`
 
 void Start () {
 stream.Open();
 stream.ReadTimeout = 25;
 }
 // Update is called once per frame`
 void Update () {
 Vector3 temp = transform.position;
 
 if (stream.IsOpen) {
 try {
 float data = stream.ReadByte();
 data = Mathf.Clamp(data, 5, 25);
 data -= 5;
 data /= 20;
 data *= 10;
 data -= 5;
 temp.x = data;
 } catch (System.Exception) {
 Debug.Log("timeout");
 }
 transform.position = temp;
 }
 
 }
 
 }

My Arduino code:

 const int TRIG = 9;
 
 const int ECHO = 10;
 
 void setup() {
 
 Serial.begin(9600);
 
 pinMode(TRIG, OUTPUT);
 
 pinMode(ECHO, INPUT);
 
 }
 
 void loop() {
 
 int data = GetUltra(TRIG, ECHO);
 
 Serial.write(data);
 
 delay(20);
 
 }
 
 double GetUltra (int trig, int echo){
 
 digitalWrite(trig , LOW);
 
 delayMicroseconds(2);
 
 digitalWrite(trig, HIGH);
 
 delayMicroseconds(8);
 
 digitalWrite(trig, LOW);
 
 double distance = ( pulseIn(echo, HIGH) )* 343.2 / 20000;
 
 return distance;
 }

Are you running the console/debugger for Arduino right now? I worked with Arduino/Unity once and would get this error if I attempted to play the Unity scene while the Arduino console was connected to the device.
