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:

Getting Started

Install the gem:

$ 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

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

$ rake make:upload
