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.

Electronic for Dummies

For who want to program Arduino  and use electronic products and same time do not understand Electronic can always buy the book "Electronic for Dummies." It is my suggestion!

I used this book to remember the basics of electronics. Long ago I didn't play with electronic! It was good times!
