Questions

How big is the Automatic night light PCB?

It measures 36 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Automatic night light use?

15 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 Automatic night light KiCad files?

From the shubhamp2007/automatic-night-light repository on GitHub, at the commit this page was made from: the board is cad/Automatic Night Light.kicad_pcb and its schematic cad/Automatic Night Light.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Automatic night light design in my own project?

Its repository states no licence, so its author keeps all rights: ask shubhamp2007 before reusing the design.
