Worked with @kymwatts to figure out bluetooth serial communication yesterday. Need to document how to get it all working so others can use it.

Windows is actually already supported if you specify the COM port manually:

board = Arduino("COM5")

Adding windows support should be as simple as adjusting the regex to match open COM ports as well.

Also need to update the documentation.

I am getting the following error when I try to compile the file:

python led.py
Traceback (most recent call last):
  File "led.py", line 7, in <module>
    from BreakfastSerial import Led, Arduino
  File "/Users/.../anaconda/lib/python3.6/site-packages/BreakfastSerial/__init__.py", line 5, in <module>
    from components import *
ModuleNotFoundError: No module named 'components'

Any idea what the problem is?

The RGB LED that came with my arduino kit is reverse polarity; that is, the common lead is actually Vcc and the individual color inputs have to be pulled LOW to turn on. I don't know if I have a weirdo defective LED or if this is a common thing.

If it's the latter, it'd be nice if we had a switch to reverse the polarity of the RGBLed object so that it pulled the pins lower to make colors brighter for LEDs configured that way.

Getting this once in a while. Looks like a pyFirmata issue.

I have problems with using the Sensor .value returning a NoneType. I can't perform any math on it.

Create a component for DC motor and document it.

This is the script I'm using to test BreakfastSerial

from BreakfastSerial import Arduino, Servo

from time import sleep

board = Arduino()
servo = Servo(board, 10)

import code
code.InteractiveConsole(locals=globals()).interact()

When running this on an Ubuntu Virtual Machine, it works fine. When running this with Raspberry Pi, this consistently happens:
