  This application lets you interact with the [GrovePi+](https://www.dexterindustries.com/grovepi/)
  and any connected sensors in Elixir. It will automatically start with your
  application an initiate a connection to the GrovePi+ board.

  To see that everything is functioning, check the firmware version on the board.

  ```elixir
  iex> GrovePi.Board.firmware_version()
  "1.2.2"
  ```

  If this doesn't work, then nothing else will. If you're running Raspbian,
  double check that I2C is enabled in `raspi-config`.
