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 *.ino and *.pde sketches as well as raw *.c and *.cpp.
  • Support for Arduino Software versions 1.x as well as 0.x.
  • 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.


From source:

  • Download latest source tarball
  • Or clone it from GitHub: git clone git://
  • Do make install to perform installation under /usr/local
  • Or see INSTALL for instructions on changing destination directory

With Python setup tools:

  • Either pip install ino
  • Or easy_install ino


  • Python 2.6+
  • Arduino IDE distribution
  • picocom for serial communication


  • As for current version, ino works only in Linux and MacOS. However it was created with other OS users in mind, so it will eventually get full cross-platform support. Help from Windows-developers is much appreciated.
