README
README.mdheart-pcb
I made this project with Hack Club guides from Sleepover and Stasis. This is a heart shaped PCB that has red blinking LEDs. I designed it using KiCad. I made the project because I wanted to learn how a circut board works and what the process of creating one requires. This is my first hardware project and I wanted to create something that was visually interesting (flashing lights are pretty cool). My process was recorded on Lapse.

Questions
How big is the Heart pcb PCB?
It measures 166 × 136 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heart pcb use?
23 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 Heart pcb KiCad files?
From the jadyn-h/heart-pcb repository on GitHub, at the commit this page was made from: the board is heart-pcb.kicad_pcb and its schematic heart-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heart pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask jadyn-h before reusing the design.
