Christmas Book Marker

Project developed for the Julialabs PCB Challenge 2021

With every New Year comes New Years's resolutions, and 2022 it will not be different.

This year I made a resolution to read more books, so I decided to make this year's PCB something to help me out with my resolution. And that's how the Christmas Book Marker was born.

It's a simple circuit using a 555 and a 4017 to make 10 LEDs light up in a linear pattern. The circuit uses a CR2032 battery to power it up.

As simple as it is, this book marker can still be very useful and give your favorite book that extra blinking lights that everybody loves.
