Home-made electronics. It's probably full of mistakes but it's fun to learn.
4017-chaser
The simplest possible use of a 4017 IC with a 555 to clock it. Works with 10mm LEDs that I had on hand.

Questions
What parts does the 4017-chaser use?
28 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 4017-chaser KiCad files?
From the pierreca/circuits repository on GitHub, at the commit this page was made from: the board is 4017-chaser/4017-chaser.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 4017-chaser design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
