Input string was not in the correct format
Anybody know why this error is happening? Input string was not in the correct format System.Int32.Parse (System.String s) This is my script.

i’m use ARDUINO in this Script

my script :

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

A way to find out what’s failing could be surrounding the parse instructions (which throw exceptions) with a try / catch block. Then you can capture the exception and analyse it to see what’s wrong.
