README.mdComputerController
Custom Computer Controller that uses a custom PCB to control the media functions of the device it is connected to, as well as view the loudness of the room.
Key Project Features
- MODE switching button that changes the use of the rotary encoder between VOLUME, MIC GAIN, BRIGHTNESS, and MIC SENSITIVITY
- PLAY, NEXT, BACK, MUTE MIC buttons
- LCD Screen that shows the current volume, mic loudness and gain, mode, if the volume is muted, if the mic is muted, and when each button is pressed
- Each component has a coupling and bulk capacitor
- LED Ring that displays the current volume level in green, and turns red when muted

Questions
How big is the ComputerController PCB?
It measures 164.5 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ComputerController use?
20 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 ComputerController KiCad files?
From the phanayden/ComputerController repository on GitHub, at the commit this page was made from: the board is hardware/design/ComputerController.kicad_pcb and its schematic hardware/schematic/ComputerController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ComputerController design in my own project?
Its repository states no licence, so its author keeps all rights: ask phanayden before reusing the design.
