# Custom Sonos Arc sound-profile controller

One-click and scheduled profiles for volume, EQ and subwoofer settings instead of repeatedly opening the stock app.

## Hardware
Sonos Arc

The software changes the real speaker’s volume, EQ and subwoofer settings.

## Shopping list

This changes control software, not the soundbar hardware. Reuse an installed Arc and its cables; no additional sensor, display or microcontroller is established.

Quantities are for one build. Unless marked source-specified, they are planning quantities; confirm kit contents and the chosen configuration before ordering.
