Story

Make a project that speaks / reacts with the Arduino board. You can upload lots of audio files and get answers with the many commands you send. In this tutorial we will learn how to play audio files with the Arduino. For this we will use speaker. Also we will use SD card module for keep the audio files.

Tutorial

About the SD Card Module Adapter:

The module (MicroSD Card Adapter) is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files.
