#       Arduino and Python Serial Communication with PySerial Part 1
# ===================================================================
# An arduino you can use baud rates 300, 600, 1200, 2400, 4800, 9600,
# 14400, 19200, 28800, 38400, 57600, or 115200. However 9600 is the
# standard baud rate usually used.
# ===================================================================
# ---- Establish a specific port and the connect
# ---- ser = serial.Serial('COM7',19200)
# ---- ser = serial.Serial('COM7', 115200, timeout=.1)
#ser = serial.Serial()          # create port
#ser.port     = 'COM7'
#ser.baudrate = 9600
#ser.timeout  = 0.1
#ser.open()                     # open connection
