# DEMO Arduino Diecimila Board and below, serial access, using standard
# Python and Windows 32 bit installs.
#
# This is an experimental idea only to test the Arduino Diecimila
# development board under Python 2.2.x to 2.6.x; (assume Python 2.6.x).
# (It is assumed that the Python install uses the default folders.)

# Copy this 'Arduino-Windows2x.py' file into the 'C:\Python26\Lib\' folder
# and you will be ready to roll... ;-)
#
# To run type:-
# >>> execfile("C:\\Python26\\Lib\\Arduino-Windows2x.py")<RETURN/ENTER>
# OR......
# >>> import Arduino-Windows2x<RETURN/ENTER>
#
# And away you go...
#
# Press ~Ctrl C~ to QUIT, OR, set input to maximum of 5V, i.e. 255.
# Do any imports as required.
