The LVL1 community will be joining in on the world-wide celebration of Arduino Day on April 2nd and we'd love for you to join us.  We will be celebrating one of the ubiquitous tools of the Maker Movement that has helped so many people by running a workshop on the Arduino hosted by Nathan Armentrout, displaying Arduino-based projects, and other activities as we get this organized.
Nathan's workshop will be from 12 to 4pm and you can sign up on the EventBrite.
Here are some of the many Arduino-based projects folks have built; many of which you can see at our space:
Many of our Sumobots are powered by Arduino.
This project converted braille to RGB light as part of a hackathon designed to make useless things.
This space monitoring station gathers various information from different sensors via an Arduino compatible chip and displays the information.
Another useless project entry; this is a 2D printer designed to self destruct when it completes a line.
One of my personal favorites; the Bad Idea Robot uses an Arduino to animate the LEDs when you press the button and it gives you a bad idea.
You can also check our Wiki for projects that use Arduino and other technologies; for example there's the Magic 8-Ball Valentines Heart and the old-school LEGO Robotics Kit given new life via Arduino.
Of course we can't forget a long-time favorite and fixture of the space; Butterscotch the Fire-breathing Robotic Pony of Doom:
