RubyPins! The simple way to control your Raspberry Pi's GPIO pins, with Ruby!

Tested operating systems: Raspian

To install, from a terminal, run:

gem install ruby_pins

If you are using a Gemfile, such as with a Ruby on Rails application add:

gem 'ruby_pins'

to your Gemfile, and run

bundle

Create a new pin:

# Pins accept a pin #, a state (:on, :off), a name, and a host.
# If you running the code on the PI itself, the pin just needs a pin number!
# The default state is off
pin = RubyPins::Pin.new pin: 17

Turn the pin on:

pin.on

Turn the pin off:

pin.off

Say what? You wanna control a Pi on your network, but run the code from a different computer? ruby_pins has you covered!

Create a host:

pi_host = RubyPins::Host.new address: <ip_address>,
                             user: <unix_user(probably 'pi')>,
                             password: <unix password>

Add this host to your pin

pin.host = pi_host

Turn the pin on:

pin.on

Turn the pin off:

pin.off

Now rewire your whole house to be interfaced from your Ruby app!

ruby_pins expects the pin number to be the pin's GPIO number. For example, when looking at the following pinout chart, if you wanted to set your pin number to the 11th pin, or GPIO17, you would pass in

pin: 17
