Show off your Arduino skills in our Arduino Challenge, brought to you by RadioShack!

The only rule for entry is that your Instructable must involve an Arduino. This can be an official Arduino, an Arduino derivative, or even Arduino Programming. Bonus points for including any code you use. What you use the Arduino for is completely up to you!

So get to it and show us something awesome. We have lots of prizes to give away for fantastic entries including a Canon Rebel DSLR and lots and lots of Arduinos and shields from RadioShack.com. We can't wait to see what you'll make!

Multiple entries are accepted, but each entrant can only win one prize. Contest is open to entries from US, Canada [excluding Quebec], UK, China, Belgium, Netherlands, and Australia. Contest closes for entries at 11:59pm PT, April 30, 2012.

The Arduino Challenge is closed.
