How to play audio files with Arduino
In this tutorial, we will learn how to play audio files with Arduino. For this we will use SD card module for keep the audio files. After this tutorial, you can make a mini mp3 player.
Hardware Required :
Project circuit :
Project circuit diagram is shown below.
Using the SD card
The first thing that we are going to do in this project is to test whether we can actually access the SD card. This will ensure that we don’t run into SD card-related problems later in the project.
