LittleBits Ruby Gem

A Ruby Gem for communicating with littleBits modules.

Currently supported are:

• cloudBit
• Arduino Module

• Ruby
• RubyGems
• Bundler
• Arduino IDE

Add this line to your application's Gemfile:

gem 'little_bits'

And then execute:

$ bundle

Or install it yourself as:

$ gem install little_bits

You'll need the Access Token and Device ID from the Settings page of the littleBits CloudBit Control Panel

You can then start up irb or create a script with the following code:

require 'little_bits'

cloud_bit = LittleBits::CloudBit.new('your-access-token', 'your-device-id')

# Set output to 100% for 3 seconds (3000 milliseconds)
cloud_bit.output(100, 3000)

# Set output to 50% indefinitely (-1 for duration)
cloud_Bit.output(50, -1)

The first argument is the percentage which should be between 0 and 100.

The second argument is the duration which should be between 0 and 32000. You can send -1 if you want the duration to be indefinite.

First, follow the littleBits Arduino Module Getting Started Guide to set up your Arduino module.

You'll need to know the serial port that the Arduino is plugged into.

You'll also need to load the StandardFirmata sketch onto your Arduino Module:

• Start the Arduino IDE
• Plug in a USB cable from your computer to the Arduino Module
• Select the serial port your Arduino is on from Tools > Serial Port
• Switch to the Arduino Leonardo board by clicking on the Tools menu, then Board > Arduino Leonardo
• Select the File menu, then Example > Firmata > Standard Firmata
• Select the File menu, then Upload

You can then start up irb or create a Ruby script with the following code:

require 'little_bits'

arduino_module = LittleBits::ArduinoModule.new('/your/serial_port')

# Turn on d1
arduino_module.d1(true)

# Set d5 to max output
arduino_module.d5(255)

# Set d9 to min output
arduino_module.d9(0)

The d1 method can be sent true or false.

The d5 and d9 methods can be sent true, false, or a number between 0 and 255.
