The Gemma has a very tiny disk drive so we have disabled Mac OS X indexing
which could take up that valuable space.
So *please* do not remove the empty .fseventsd/no_log, .metadata_never_index
or .Trashes files!
#############################
The pre-loaded demo shows off what your Gemma M0 can do with CircuitPython:
* The built in DotStar LED can show any color, it will swirl through the rainbow
* Pin A0 is a true analog output, you will see the voltage slowly rise
* Pin A1 is an analog input, the REPL will display the voltage on this pin
(0-3.3V is the max range)
* Pin A2 is a capacitive input, when touched, it will turn on the red LED.
If you update main.py to uncomment the relevant lines, it will act as a
mini keyboard and emulate an 'a' key-press whenever A2 is touched.

CircuitPython Quick Start:
Changing the code is as easy as editing main.py in your favorite text editor.
We recommend Atom, Notepad++, or Visual Studio Code. After the file is saved,
CircuitPython will automatically reload the latest code. Try enabling the
capacitive keyboard (HINT: look for the "# optional! uncomment below..." text)
Connecting to the serial port will give you access to better error messages and
interactive CircuitPython (known as the REPL). On Windows we recommend Tera Term
or PuTTY. On Mac OSX and Linux, 'screen' can be used from a terminal.
