[Tom Goff]’s kids had some pretty cool ideas for building a decoration, like a musical, lighted sleigh complete with robotic Santa Claus. While that’s a little much to pull off for this year, they did salvage the music and lights part for their Hackvent calendar.

There are 24 small LEDs for December 1st through the 24th, and a big white star for December 25th. Each day, the kids just push the button and the day’s LED lights up. On the big day, all the small lights cascade off and the white one lights up, then it plays Jingle Bells through a sound playback module.

Each LED is connected directly to an input on an Arduino Mega. While there are several ways of lighting up 25 LEDs, this one is pretty kid-friendly.
