“In this project we will make our own audio player with esp 32. This project is a simple project to test a voice output from esp 32.
We can seemany projectsin the internet to play music with esp 32 usingI2S Protocol. For that you need a separate SD card slot where you can plug in your SD card filled with music. You can play that mp3 file of that SD card with the help of speaker by using I2S protocol. In this project we are doing the same thing differently without using SD card module. In this project ESP 32 Based Audio Player We have connected one of the DAC pin of Esp -32 to amplifier where two terminals of speaker are connected. The audio output may not be loud but this application shows the ability of the ESP32 board to play audio files.”
