Volume control using DigiPot controlled by infrared remote control.
IR Controllable Digipot
This part of the project is a what is actually controlling sound volume. It is a digipot which is controlled by an infrared remote controller (similar to the ones used by TVs).
The design and firmware files are in the IR-Digipot folder.
IR Controller
This is a minimalistic implementation of infrared remote controller. It talks
to the IR-Digipot. Can be easily extended with more buttons to consolidate
all the remote controllers in the house!

Questions
How big is the IR Controller PCB?
It measures 40.1 × 80.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IR Controller use?
12 parts, built around the CRGCQ0402F10K, MCSLPT4644B1TR, BC-2003-TR and IN-S126ESGHIR. 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 IR Controller KiCad files?
From the sergeyvfx/IR-Volume-Control repository on GitHub, at the commit this page was made from: the board is IR-Controller/hardware/IR-Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IR 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).
