UnitySerianHandloerのUnity2018で使えたやつ

Unityボタン側スクリプト
Btn.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Btn : MonoBehaviour
{
//先ほど作成したクラス
public SerialHandler serialHandler;
void Start()
{
//信号を受信したときに、そのメッセージの処理を行う
serialHandler.OnDataReceived += OnDataReceived;
}
void Updata()
{
//文字列を送信
// serialHandler.Write("hogehoge");
}
//受信した信号(message)に対する処理
void OnDataReceived(string message)
{
var data = message.Split(
new string[] { "\t" }, System.StringSplitOptions.None);
if (data.Length < 2) return;
try
{
}
catch (System.Exception e)
{
Debug.LogWarning(e.Message);
}
}
/////ここから追加します

public void sendOn()
{
//Arduinoに文字列onを送る
serialHandler.Write("4");
}
public void sendOff()
{
//
serialHandler.Write("5");
}
public void ledOn()

Arduino側コード
