Artoo Adaptor For Raspberry Pi
This repository contains the Artoo (http://artoo.io/) adaptor for the Raspberry Pi (http://www.raspberrypi.org/) tiny Linux computer's General Purpose Input/Output (GPIO).
Artoo is a open source micro-framework for robotics using Ruby.
For more information about Artoo, check out our repo at https://github.com/hybridgroup/artoo
This gem makes extensive us the the pi_piper gem (https://github.com/jwhitehorn/pi_piper) thanks to @jwhitehorn
Installing On Raspberry Pi
If you do not already have Ruby installed, first you'll need to:
sudo apt-get install ruby ruby1.9.1-dev
Despite one of the packages being titled "ruby1.9.1-dev", the above command will install Ruby 1.9.3 (as of January 2013) and the Ruby dev tools.
Then install the artoo-raspi gem:
sudo gem install artoo-raspi
Using
require 'artoo'
connection :raspi, :adaptor => :raspi
device :led, :driver => :raspi_pin, :pin => 17, :direction => :out
work do
every 1.second do
led.toggle
end
end
To run the examples, requires sudo access on the Raspberry Pi:
sudo ruby examples/raspi_led.rb
Connecting to Raspberry Pi GPIO
This gem only works on a real Raspberry Pi. Do not bother trying on any other kind of computer it will not work. Also note you will need to connect actual circuits to the Raspberry Pi's GPIO pins. Here is an example of wiring the circuits for the GPIO to connect a single LED:
To add the button used in the example, add a momentary contact switch to the circuit.
