    Serial Com VB 2010

    hi guys. i`m new to vb and here to seek advice regarding data received in serial com. i`m trying to make external hardware to control Interface in vb, which is arduino. the thing is, both serial works fine, however when i try to send "1" from arduino (even though when i monitor the serial output, it do came out "1") vb receive higher value which is 255. does the data receive thru serial to vb add up as it receive? i already tried to receive string input, end up the same and sometimes dont even works. what did i do wrong in serial receive? thanks in advanced

    Public Class Form1
        Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            pic1.Visible = False
            pic2.Visible = False
        End Sub
        Private Sub btnOpen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpen.Click
            SerialPort1.PortName = "com3"
            SerialPort1.BaudRate = 9600
            SerialPort1.Encoding = System.Text.Encoding.Default
            btnOpen.Enabled = False
        End Sub
        Sub DataReceived()
            Dim receiveData As Integer
            receiveData = SerialPort1.ReadChar
            txtReceive.Text = receiveData
            If receiveData = 1 Then
                pic1.Visible = True
            End If
            If receiveData = 2 Then
                pic2.Visible = True
            End If
        End Sub
        Delegate Sub ConnectedCallBack()
        Private Sub SerialPort1_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
            Dim D As New ConnectedCallBack(AddressOf DataReceived)
            Catch ex As Exception
            End Try
