DESCRIPTION

       The arduino integrated development environment allows editing, compiling and uploading
       sketches (programs) for Arduino (and compatible) microcontroller boards.

       Normally, running the arduino command starts the IDE, optionally loading any .ino files
       specified on the commandline.

       Alternatively, if any of the following command line options is given, no graphical
       interface will be shown and instead a one-off verify (compile) or upload will be done. A
       single .ino file should be given. If the sketch contains multiple .ino files, any one can
       be specified on the commandline, but the entire sketch will be compiled.

       When running in a one-off mode, it might be useful to set the build.path preference to
       allow keeping intermediate build results between multiple runs and only recompile the
       files that changed.

       Note that on MacOS X, the main executable is Arduino.app/Contents/MacOS/Arduino instead of
       arduino.

       Note that on Windows, due to the diffence between GUI and console apps, that the
       arduino_debug.exe is the appropriate executable to use if you want to use the majority of
       these command line options. The arduino.exe GUI version of the launcher may perform some
       of the functions described below, but will not output any messages to the console, meaning
       it is pretty useless if you want any feedback or to be able to keep log files for
       automated testing, etc.

       ACTIONS

       --verify
           Build the sketch.

       --upload
           Build and upload the sketch.

       --get-pref [preference]
           Prints the value of the given preference to the standard output stream. When the value
           does not exist, nothing is printed and the exit status is set (see EXIT STATUS below).
           If no preference is given as parameter, it prints all preferences.

       --install-boards package name:platform architecture[:version]
           Fetches available board support (platform) list and install the specified one, along
           with its related tools. If version is omitted, the latest is installed. If a platform
           with the same version is already installed, nothing is installed and program exits
           with exit code 1. If a platform with a different version is already installed, it’s
           replaced.

       --install-library library name[:version]
           Fetches available libraries list and install the specified one. If version is omitted,
           the latest is installed. If a library with the same version is already installed,
           nothing is installed and program exits with exit code 1. If a library with a different
           version is already installed, it’s replaced. Multiple libraries can be specified,
           separated by a comma.

       --version
           Print the version information and exit.

OPTIONS

       --board package:arch:board[:parameters]
           Select the board to compile for.

           •   package is the identifier of the vendor (the first level folders inside the
               hardware directory). Default arduino boards use arduino.

           •   architecture is the architecture of the board (second level folders inside the
               hardware directory). Default arduino boards use either arduino:avr for all
               AVR-based boards (like Uno, Mega or Leonardo) or arduino:sam for 32bit SAM-based
               boards (like Arduino Due).

           •   board is the actual board to use, as defined in boards.txt contained in the
               architecture folder selected. For example, arduino:avr:uno for the Arduino Uno,
               arduino:avr:diecimila for the Arduino Duemilanove or Diecimila, or
               arduino:avr:mega for the Arduino Mega.

           •   parameters is a comma-separated list of boards specific parameters that are
               normally shown under submenus of the "Tools" menu. For example
               arduino:avr:nano:cpu=atmega168 to Select the mega168 variant of the Arduino Nano
               board.

           If this option is not passed, the value from the current preferences is used (e.g.,
           the last board selected in the IDE).

       --port portname
           Select the serial port to perform upload of the sketch. On linux and MacOS X, this
           should be the path to a device file (e.g., /dev/ttyACM0). On Windows, this should be
           the name of the serial port (e.g., COM3).

           If this option is not passed, the value from the current preferences is used (e.g.,
           the last port selected in the IDE).

       --verbose-build
           Enable verbose mode during build. If this option is not given, verbose mode during
           build is disabled regardless of the current preferences.

       --preserve-temp-files
           Keep temporary files (preprocessed sketch, object files...) after termination. If
           omitted, temporary files are deleted.

           This option is only valid together with --verify or --upload.

       --useprogrammer
           Upload using a programmer. Set if you’re using an external programmer, or using the
           Arduino as ISP.

       --verbose-upload
           Enable verbose mode during upload. If this option is not given, verbose mode during
           upload is disabled regardless of the current preferences.

           This option is only valid together with --verify or --upload.

       -v, --verbose
           Enable verbose mode during build and upload. This option has the same effect of using
           both --verbose-build and --verbose-upload.

           This option is only valid together with --verify or --upload.

       --preferences-file filename
           Read and store preferences from the specified filename instead of the default one.

       --pref name=value
           Sets the preference name to the given value.

           Note that the preferences you set with this option are not validated: Invalid names
           will be set but never used, invalid values might lead to an error later on.

       --save-prefs
           Save any (changed) preferences to preferences.txt. In particular --board, --port,
           --pref, --verbose, --verbose-build and --verbose-upload may alter the current
           preferences.

PREFERENCES

       Arduino keeps a list of preferences, as simple name and value pairs. Below, a few of them
       are documented but a lot more are available.

       sketchbook.path
           The path where sketches are (usually) stored. This path can also contain some special
           subdirectories (see FILES below).

       update.check
           When set to true, the IDE checks for a new version on startup.

       editor.external
           When set to true, use an external editor (the IDE does not allow editing and reloads
           each file before verifying).

       build.path
           The path to use for building. This is where things like the preprocessed .cpp file,
           compiled .o files and the final .hex file go.

           If set, this directory should already exist before running the arduino command.

           If this preference is not set (which is normally the case), a new temporary build
           folder is created on every run and deleted again when the application is closed.

EXIT STATUS

       0
           Success

       1
           Build failed or upload failed

       2
           Sketch not found

       3
           Invalid (argument for) commandline option

       4
           Preference passed to --get-pref does not exist

FILES

       %LOCALAPPDATA%/Arduino15/preferences.txt (Windows), ~/Library/Arduino15/preferences.txt
       (Max OS X), ~/.arduino15/preferences.txt (Linux)
           This file stores the preferences used for the IDE, building and uploading sketches.

       My Documents/Arduino/ (Windows), ~/Documents/Arduino/ (Mac OS X), ~/Arduino/ (Linux)
           This directory is referred to as the "Sketchbook" and contains the user’s sketches.
           The path can be changed through the sketchbook.path preference.

           Apart from sketches, three special directories can be inside the sketchbook:

           libraries
               Libraries can be put inside this directory, one library per subdirectory.

           hardware
               Support for third-party hardware can be added through this directory.

           tools
               External code-processing tools (that can be run through the Tools menu of the IDE)
               can be added here.

EXAMPLES

       Start the Arduino IDE, with two files open:

           arduino /path/to/sketch/sketch.ino /path/to/sketch/extra.ino

       Compile and upload a sketch using the last selected board and serial port

           arduino --upload /path/to/sketch/sketch.ino

       Compile and upload a sketch to an Arduino Nano, with an Atmega168 CPU, connected on port
       /dev/ttyACM0:

           arduino --board arduino:avr:nano:cpu=atmega168 --port /dev/ttyACM0 --upload /path/to/sketch/sketch.ino

       Compile a sketch, put the build results in the build directory an re-use any previous
       build results in that directory.

           arduino --pref build.path=/path/to/sketch/build --verify /path/to/sketch/sketch.ino

       Change the selected board and build path and do nothing else.

           arduino --pref build.path=/path/to/sketch/build --board arduino:avr:uno --save-prefs

       Install latest SAM board support

           arduino --install-boards "arduino:sam"

       Install AVR board support, 1.6.2

           arduino --install-boards "arduino:avr:1.6.2"

       Install Bridge library version 1.0.0

           arduino --install-library "Bridge:1.0.0"

       Install Bridge and Servo libraries

           arduino --install-library "Bridge:1.0.0,Servo:1.2.0"

HISTORY

       1.5.2
           Added initial commandline support. This introduced --verify, --upload, --board,
           --port, --verbose and -v.

       1.5.5
           Added support for board-specific parameters to --board.

           Sketch filenames are now interpreted relative to the current directory instead of the
           location of the arduino command itself.

       1.5.6
           Introduced --pref, --preferences-file, --verbose-build and --verbose-upload.

           Preferences set through --pref are remembered, preferences set through --board, --port
           or the --verbose options are not.

           When running with --verify or --upload, the full GUI is no longer shown. Error
           messages still use a graphical popup and on Windows, the splash screen is still shown.

       1.5.8
           Introduced --save-prefs.

       1.6.2
           Main executable in MacOS X changed from Arduino.app/Contents/MacOS/JavaApplicationStub
           to Arduino.app/Contents/MacOS/Arduino.

       1.6.4
           Introduced --install-boards and --install-library.

           --pref options are now not saved to the preferences file, just like --board and
           --port, unless --save-prefs is specified.

           A path passed to --preferences-file, or set in the build.path, preferences.path or
           settings.path is now interpreted relative to the current directory instead of the
           location of the arduino command itself.
