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 rad.rubyforge.org
The main documentation is here: ArduinoSketch.
See also the Arduino Software reference: www.arduino.cc/en/Reference/HomePage
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: github.com/atduskgreg/rad/wikis
To install the edge gem:
# Update to RubyGems 1.2.0 before proceeding! $ gem sources -a http://gemcutter.org (you only have to do this once) $ sudo gem install madrona-rad
A very old and feature poor (though slightly more 'stable' RAD) is available from RubyGems:
$ sudo 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 end end
Attach your Arduino and use rake to compile and upload your sketch:
$ rake make:upload
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.
For OS X, Arduino should be installed in your applications directory -- install the intel or power pc drivers in /drivers
