When my girlfriend and I moved into our small apartment in San Francisco we wanted to setup some sort of compact liquor cabinet and wine rack. After a quick trip to IKEA we had a bookshelf we could easily convert into a fancy boozeshelf unit! *insert music montage here* After adding holders for wine glasses and bottles it was good, but still a bit boring and not quite perfect. At night it would just stand there against the wall in a shadow, not presenting our handiwork at all. A true insult to all the alcohol we had on display. I felt like it needed something more — some light…and sensors…and might as well throw in a dance party while I’m at it.
The simple LED fading demos are great for learning Arduino, but when you actually need your processor to be doing something — like receiving serial input or reading a sensor — fading your LEDS can get in the way.
