My Barduino (shameless self promotion).<p>Ruby + Arduino = Drink dispensing Barmonkey driven by a Ruby DSL that cost me like $50 to build.<p>Example recipe:<p>drink 'Screwdriver' do<p><pre><code> serve_in 'Highball Glass'
ingredients do
2.ounces :vodka
5.ounces :orange_juice
end

The micrcontroller community today is analogous to the personal computer/homebrew computer clubs in the early 70's - except with more embedded applications.<p>I've written code for one Arduino to run a python script to order pizza when one pushes a button (this used to be on my fridge.)<p>I used Arduinos as the processing, communications, and power modules for an augmented reality/robotics project where virtual balls projected on a dry erase board bounced off robotic devices (like a see-saw) and the devices reacted appropriately.<p>Currently I'm writing a program for the Atmel to query how many days left until YC demo day - and light up a corresponding massive LED display mounted on our wall.<p>You should check out LadyAda's site - most of her modules totally rock - especially the xbee and motor shield stuff. <a href="http://adafruit.com/" rel="nofollow">http://adafruit.com/</a>
I'm using mine to replace the ignition system on my motorcycle (1979 Honda CX500). The original system is a lovely piece of electrical engineering, but is prone to stator coil and capacitor failure (respectively, by heat and age). The Arduino will allow proper ignition timing to be maintained even as three of four timing coils fail.
I was lucky enough to work on this: <a href="http://www.bbc.co.uk/blogs/radiolabs/2008/12/the_rockterscale.shtml" rel="nofollow">http://www.bbc.co.uk/blogs/radiolabs/2008/12/the_rockterscal...</a><p>The hat of rock was my invention :-)<p>Abdel A Saleh, <a href="https://twitter.com/abdels" rel="nofollow">https://twitter.com/abdels</a>

The brief description of this little Arduino project why did was enough to get me started: <a href="http://twitter.com/_why/status/1065757843" rel="nofollow">http://twitter.com/_why/status/1065757843</a><p>I'd love to see it in person.

Here is my twitter based home security system. I'm using phidgets but I have ordered an Arduino and will update the code. Making software do things in the "real" world is a lot of fun.<p><a href="http://www.instructables.com/id/Combining-security-system-with-phidges-and-twitter/" rel="nofollow">http://www.instructables.com/id/Combining-security-system-wi...</a>

I connected a PS2 barcode reader to a Sanguino, and programmed it to store the scans in memory, then dump them when sent a specific serial command. This allows me to scan a pile of books for LibraryThing when I'm not at my computer.
On my wall at work, used to monitor the health of my servers.<p><a href="http://www.82smugglers.com/blog/?p=7" rel="nofollow">http://www.82smugglers.com/blog/?p=7</a>
