This repository contains the Artoo (http://artoo.io/) adaptor and drivers for Arduino and Arduino-compatible microcontrollers (http://arduino.cc/) using the Firmata protocol (http://firmata.org).
Artoo is a open source micro-framework for robotics using Ruby.
For more information abut Artoo, check out our repo at https://github.com/hybridgroup/artoo
This gem makes extensive use of the hybridgroup fork of the firmata gem (https://github.com/hybridgroup/firmata) thanks to @hardbap with code borrrowed from the arduino_firmata gem (https://github.com/shokai/arduino_firmata) thanks to @shokai
gem install artoo-arduino
require 'artoo'
connection :arduino, :adaptor => :firmata, :port => '/dev/ttyACM0' #linux
device :board, :driver => :device_info
device :led, :driver => :led, :pin => 13
work do
puts "Firmware name #{board.firmware_name}"
puts "Firmata version #{board.version}"
every 1.second do
led.toggle
end
end
The following hardware devices have driver support via the artoo-gpio gem:
- Button
- LED
- Maxbotix ultrasonic range finder
- Analog sensor
- Motor (DC)
- Servo
The following hardware devices have driver support via the artoo-i2c gem:
- Wiichuck controller
- Wiiclassic controller
The main steps are:
- Install the artoo-arduino gem
- Find out what serial port your arduino is connected to
- Upload the Firmata protocol to the arduino
- Connect to the device via Artoo
First plug the Arduino into your computer via the USB/serial port. A dialog box will appear telling you that a new network interface has been detected. Click "Network Preferences...", and when it opens, simply click "Apply".
Install the artoo-arduino gem:
$ gem install artoo-arduino
Install the hybridgroup-serialport gem:
$ gem install hybridgroup-serialport
Once plugged in, use the artoo connect scan -t serial
command to find out your connection info and serial port address:
$ artoo connect scan -t serial
Use the artoo firmata install
command to install avrdude,
this will allow us to upload firmata to the arduino:
$ artoo firmata install
Once the avrdude uploader is installed we upload the firmata protocol to
the arduino, use the arduino serial port address found when you ran artoo connect scan -t serial
, or leave it blank to use the default address /dev/ttyACM0
:
$ artoo firmata upload /dev/ttyACM0
Change the example to use the correct serial port address
connection :arduino, :adaptor => :firmata, :port => '/dev/ttyACM0' #linux
connection :arduino, :adaptor => :firmata, :port => '/dev/tty.usbmodem1411' #osx
We are currently working with the Celluloid team to add Windows support. Please check back soon!
