ESP32 Music Receiver

This project implements a music receiver using an ESP32 microcontroller. It combines WiFi, Bluetooth A2DP, IR remote control, and physical button functionality to create a versatile audio device.

Features

• WiFi connectivity for network-based features
• Bluetooth A2DP sink for wireless audio streaming
• IR remote control support for device control
• Physical buttons for play/pause, next, and previous track control
• FreeRTOS task for responsive button handling

Hardware Requirements

• ESP32 development board
• IR receiver (e.g., TSOP38238)
• IR transmitter (optional)
• Push buttons (3x)
• Audio output device (e.g., I2S DAC or amplifier)

Software Dependencies

• Arduino core for ESP32
• ESP32-A2DP library
• Arduino-audio-tools library
• IRremote library

Setup

1. Clone this repository
2. Open the project in PlatformIO
3. Copy credentials_example.h to credentials.h and update with your WiFi credentials
4. Update config.h with your specific pin assignments and other settings
5. Build and upload the project to your ESP32

Usage

• Power on the device and wait for it to connect to WiFi
• Pair your Bluetooth device with "ESP32 Music Receiver"
• Use the IR remote or physical buttons to control playback
• The device will automatically reconnect to WiFi if the connection is lost

File Structure

• main.cpp: Main program logic
• config.h: Configuration settings
• credentials.h: WiFi credentials (not tracked in git)
• wifi_manager.h/cpp: WiFi connection management
• bluetooth_manager.h/cpp: Bluetooth A2DP functionality
• ir_manager.h/cpp: IR remote control handling
• button_manager.h/cpp: Physical button handling
