Communicating between PC and Arduino (Correction)

On March 19th, 2012, a youtube user called Sophie333C found a problem on video "Communicating between PC and Arduino".

Sophie333C's comment:
Hi, There seems to be a problem when you press send the second time around,
it only seems to update every second press of the button!

After two days, she sent me a solution. I tested her solution and it works fine. Now I can receive a answer
when I press the button for first time. Here is code of solution:

  answer = port_arduino.ReadByte()
        TextBox2.Text = Chr(answer)

I would like thank to Sophie333C to found out this problem.

You will need install Visual Basic 2008 and Arduino environment. With Arduino environment, copy the code source from the next image.

Finally, copy the next code source to Visual Basic 2008 from the next images.

The User Interface (UI) is something like this:
