Often times, we have the need for a way to store data in our projects, and most of the time, the EEPROM which comes readily to mind has a limited storage capacity, and issues with the format and nature of data it can hold. All this and more makes it probably not the best for storing data like text, CSV, audio, video or image files. To get around this we could use an SD card to store the data, and remove the card when we need to view on some other platform etc. That is why today’s project is focusing on how to interface an SD card module with an Arduino.
The Arduino Micro SD card Module is an SPI Communication based device. It is compatible with the TF SD cards used in mobile phones and can be used to provide some sort of external storage for micro controller and microprocessor based projects, to store different kind of data types from images to videos. SD cards generally are 3.3v logic level based devices, but with the aid of the Micro SD card module, the signals are converted to 5v via a logic level converter implemented on the SD card Module.
To achieve the goals of this tutorial i.e. learn to interface the Arduino with the Micro SD card module, we will need the following components;
