Welcome to RAD (Ruby Arduino Development)

RAD is a framework for programming the Arduino physcial computing platform using Ruby. RAD converts Ruby scripts written using a set of Rails-like conventions and helpers into C source code which can be compiled and run on the Arduino microcontroller. It also provides a set of Rake tasks for automating the compilation and upload process.

For a full introduction see


The main documentation is here: ArduinoSketch.

See also the Arduino Software reference:


See the examples directory for lots of examples of RAD in action:

The atduskgreg/rad wiki also contains a growing library of examples and hardware tutorials:

Getting Started

To install the gem:

$ gem install rad

Run the rad command to create a new project:

$ rad my_project

Write a sketch that will blink a single LED every 500ms:

class MyProject < ArduinoSketch
  output_pin 13, :as => led
  def loop
    blink led, 500

Attach your Arduino and use rake to complile and upload your sketch:

$ rake make:upload

##Installing the Arduino Software

Installing RAD and the Arduino software on Linux can be a little more difficult than on OS X. Thankfully, the RAD command line tool can help. Run:

$ rad install arduino

And RAD will do its best to get the Arduino software installed on your system.

#Get Involved

##Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix on a new topic branch
  • Add specs and cukes for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Issue a pull request.
