Dino lets you start programming your Arduino with Ruby in minutes.

gem install dino

Use the included command line tool to create a folder with the Arduino sketch you want to use and optionally configure it.

# If connecting via serial, USB or ser2net, this is all you should need:
dino generate-sketch serial

# If usng the ethernet shield, you'll want to specify unique MAC and IP addresses:
dino generate-sketch ethernet --mac XX:XX:XX:XX:XX:XX --ip XXX.XXX.XXX.XXX

# For more options:
dino help

Note: Current Ethernet shields come with a sticker indicating the MAC address you should use with them. For older shields without a dedicated MAC address, inventing a random one should work, but don't use the same one for multiple boards. Valid IP addresses depend on the configuration of your network.

• Connect the Arduino to a USB port on your machine, regardless of which sketch you're using.
• Open the normal Arduino IDE
• Open the .ino file in the sketch folder you just generated.
• Click the upload button (an arrow).

• Build the sample circuit examples/led/led.png
• From your terminal, execute ruby examples/led/led.rb
• Observe your LED blinking continuously

• Take a look in the example directory for small component examples
• Try Getting Started with Arduino and Dino from Jumpstart Lab, building a number-guessing game and a simple nightlight
