Questions
What parts does the Smart LED Controller use?
19 parts, built around the ATMEGA328P-PU. 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 Smart LED Controller KiCad files?
From the Venkat1512-git/Smart-LED-Controller-PCB repository on GitHub, at the commit this page was made from: the board is Hardware/PCB/Smart LED Controller.kicad_pcb and its schematic Hardware/Schematic/Smart LED Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart LED Controller 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).
