README
README.mdProgrammable Light Controller
Programmable light is a low cost and easy to build LED light controller. The main objective of this project is to design a maintenance free light which automatically on and off at the predetermined time of the day.
This light controller is based on ATmega8 microcontroller and DS1307 real time clock. It is designed to handle commonly available 24V - 7W LED modules.
This is certified open source hardware project. All the design files, documentation, firmware source code are available to download at the project source repository. All the content of this project are distributed under the terms of the following license:

Questions
How big is the Programmable light PCB?
It measures 52.2 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Programmable light use?
55 parts, built around the ATMEGA8L-8AU, MC34063AD, DS1307Z+T&R and MMBT3904. 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 Programmable light KiCad files?
From the dilshan/programmable-light repository on GitHub, at the commit this page was made from: the board is design/programmable-light.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Programmable light 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).
