From the project

source code and hardware schematics for a Bluetooth phased array directional speaker built using ESP32

This repository contains the source code and hardware schematics for a Bluetooth phased array directional speaker built using ESP32 and ESP-IDF.

The project aims to create a speaker that can project a beam of sound in a specific direction using a phased array, allowing for a more targeted listening experience. The speaker is connected via Bluetooth to any compatible device, such as a smartphone or laptop.
