README

FunTime is a simple DIY clock kit, that doubles up as automatic night lamp. While building this kit we learn about how time is computed, converted to secs, mins, hours, days and eventually into years! We will also learn about measuring light and controlling a LED depending on time and light. The end goal is build a cool wall clock, use the time and the light intensity to turn on the night lamp. It will take about an hour to solder and assemble the kit.

Questions
How big is the Explore Clock PCB?
It measures 75.1 × 45.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Explore Clock use?
34 parts, built around the ATMEGA328P-PU, BC547, BD139 and CR2032弯脚电池片铜 3V. 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 Explore Clock KiCad files?
From the ExploreEmbedded/FunTime repository on GitHub, at the commit this page was made from: the board is HW Design/Kicad Files/Explore Clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Explore Clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
