   Hi Lucas,
   Glad you're enjoying the library!
   Strange issue with rerunning codes in input mode. I'm out of town at the
   moment, but I'll try and reproduce it & plan a fix when I get home. Thanks
   for pointing it out!

   Hi,

   Before explaining the issue I have with your project, let me express how
   great I find it ! It is doing exactly what I need, thank you !

   However I had some troubles when using a pin mode as "INPUT". For instance
   when running the following simple example :

   from Arduino import Arduino

   board = Arduino('9600') #plugged in via USB, serial com at rate 9600
   board.pinMode(5,"INPUT")
   board.close()

   everything runs fine. However, if I run this same code a second time I get
   the following output :

   File "./TestArduino.py", line 23, in
   board = Arduino('9600') #plugged in via USB, serial com at rate 9600
   File
   "/usr/local/lib/python2.6/dist-packages/arduino_python-0.2-py2.6.egg/Arduino/arduino.py",
   line 106, in init
   raise ValueError("Could not find port.")
   ValueError: Could not find port.

   But then it works again if I disconnect and reconnect the Arduino. Such an
   issue is not happening if I replace "INPUT" by "OUTPUT". The versions of
   Python and python-serial are respectively 2.6.5 and 2.7.

   The issue I have is then not a major obstacle since I can just reconnect
   the Arduino board. But I was thinking that you may want to give this a look.
