My girlfriend and I have been together for more than seven years, and this year I finally had a great Valentine’s idea! I’ve combined a strip of WS2812B addressable RGB LEDs with an Arduino, a real-time clock and a beautiful heart-shaped boutique paper box to make an ornament for my wonderful Valentine.
It displays the time, in seconds, in binary, since we met… (of course, it’s slightly approximate — I forget the precise second we met, but I think I know to within about 30 minutes!) For good measure, there’s some subtle color-cycling going on in the background, and I have added some “special features” to make it more exciting and allow it to be used as a rudimentary clock as well.
