This is the first project posted here on Codeduino.com and what a belter! The Romance Pants are a pair of jeans that dim the lights and turn up the music when the fly zipper is pulled down. When the waist button is undone, candles are automatically ignited to create the perfect mood - handy for when you are too busy to do it yourself.
This entry to the Red Bull Creation Contest 2012 goes to show that the Arduino isn't all about serious, boring projects!
