Understanding the Basics of SD Card Interfacing

SD cards, including their smaller MicroSD counterparts, are a popular choice for expandable storage due to their affordability, capacity, and ease of useReading and Writing Files from an SD Card with an Arduino To connect an SD card module to an Arduino, you'll typically be using the Serial Peripheral Interface (SPI) protocolSD Card Module With Arduino How to Read/Write Data This protocol allows for efficient communication between the Arduino and the SD card reader moduleSD Card Module with Arduino How to Read or Write Data The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 on most Arduino boardsSD | Arduino Documentation

Required Hardware for Connection

To begin, you will need a few key components:

* Arduino Board: Any standard Arduino board like the Arduino Uno, Mega, or even more advanced boards like the ESP32 can be used for this projectToconnecta microSD cardto ourArduinoMega, we will use an Ethernet shield with a micro SDsloton it. There are, however, many different shields available
