Command line toolkit for working with Arduino hardware

Project description

Ino is a command line toolkit for working with Arduino hardware

It allows you to:

  • Quickly create new projects
  • Build a firmware from multiple source files and libraries
  • Upload the firmware to a device
  • Perform serial communication with a device (aka serial monitor)

Ino may replace Arduino IDE UI if you prefer to work with command line and an editor of your choice or if you want to integrate Arduino build process to 3-rd party IDE.

Ino is based on make to perform builds. However Makefiles are generated automatically and you’ll never see them if you don’t want to.


  • Simple. No build scripts are necessary.
  • Out-of-source builds. Directories with source files are not cluttered with intermediate object files.
  • Support for *.pde and *.ino sketches as well as raw *.c and *cpp.
  • Automatic dependency tracking. Referred libraries are automatically included in the build process. Changes in *.h files lead to recompilation of sources which include them.
  • Pretty colorful output.
  • Support for all boards that are supported by Arduino IDE.
  • Fast. Discovered tool paths and other stuff is cached across runs. If nothing has changed, nothing is build.
  • Flexible. Support for simple ini-style config files to setup machine-specific info like used Arduino model, Arduino distribution path, etc just once.


With python setup tools:

$ sudo pip install ino
# ... or ...
$ sudo easy_install ino

Or clone from GitHub:

$ git clone git://
$ export PATH=`pwd`/ino/bin


  • Python 2.6+
  • Arduino IDE distribution
  • make and avr-gcc for building
  • picocom for serial communication


  • As for current version, ino works only in Linux. However it was created with other platform users in mind, so it will eventually get cross-platform support. Help from Windows- and MacOS- developers is much appreciated.
  • Ino is not yet well tested with release candidate of upcoming Arduino 1.0 software. Although it should be compatible.
