I have a arduino project that I am working on. I need the 10 characters changed from ASCII to Hex and Base32. I have the Hex working but I can not figure out how to convert to the Base32. Here is my code. I have been all overGoogle and I cannot find any clear answer. Any help or a point in the right direction would be great.

Code:
    Private Sub Clear_Click(sender As Object, e As EventArgs) Handles Clear.Click
        txtbox.Text = ""
        arduino.Text = ""
        Auth.Text = ""
    End Sub

    Private Sub Ok_Click(sender As Object, e As EventArgs) Handles Ok.Click

        arduino.Text = "{" & String.Join(", ", txtbox.Text.Select(Function(c) String.Format("0x{0:X2}", Convert.ToInt32(c)))) & "}"

    End Sub

End Class
