FUNWITHCODE: Binary Christmas Calendar

Disclosure: Please do not judge me on the pertinence of working on this project. The background of this prototype development is that I have a girlfriend who really loves Christmas. And I am a boyfriend, who really loves binary.

Ok so let’s start on that journey by showing you the end result. Of course, it is not the most beautiful Christmas calendar. But it is a working binary calendar, teaching my girlfriend how to read binary day numbers.

Right, so here the actual working calendar, on Tuesday 6th December 2018:

The actual calendar feature is to transcribe the current date day number into its binary representation and display this on the LEDs accordingly. Additionally, during the Advent period of this month of this December, my girlfriend has to unroll post-its on which she can see the binary representation of the day as well.
