Since this was just a demo sketch to show how to read and write files, there was no point to run the code multiple times so they were all placed in the void setup() function which runs just once, instead of putting it in a void loop which runs for as long as you have power. It should be noted that the prefs.txt file was already created on the SD card initially or else we would have an error when we tried to open it. After the data has been read, we close the file. The first thing we do is open the file, then we use the next line of code to print each line of the text found in the file using the readline() function.

With that done we then move to the second part of the void setup where we will attempt to read the data stored in a file and display it on the serial monitor. This section of the void setup() function was just used to demonstrate how easy it is to write text/data to a file. We then initialize the SD card with the next line of code, after which we create a file named test.txt and then write to it using the writeToFile() function. The first thing we do is start the serial communication at 9600 baud rate. Next we move to the setup() function of the arduino code. After declaring the pin, we then create an object file, which will be used later on to store data on the SD card. We didn’t need to declare the other SPI pins since we are connected to the generic SPI pins and we have the SPI library included. The CS pin is the only one that is not really fixed as any of the Arduino digital pin. Get the latest version of the code here: // We will basically be using the Arduino SD library and the SPI.h library which allows us to easily use the Arduino hardware SPI. So to jump right in, the first thing we do in the code is include the libraries that we will be using as shown below.

The code will also be attached in a zip file at the end of this post.

The aim of this code is to basically show us the functions that can be performed with the SD card module, including read, write, etc.Īs usual, I will do a breakdown of the code here, and will then drop the full code at the end. It is one of the libraries that comes with the the installation of the IDE. The code for this tutorial will be based on the standard SD.h arduino library. To further highlight the connection made in the fritzing schematics above, below is a pin map of the connection between the SD card and the Arduino Uno The SPI pins on an Arduino differs from one arduino to the other, but on the UNO which was used for this project, it is found between pin 10 to 12. The SD card module as earlier stated, communicates with the arduino over the SPI (serial Peripheral interface) communication protocol and it is connected to the arduino hardware SPI pins. SchematicsĬonnect all the components as shown in the schematics below. learn to interface the Arduino with the Micro SD card module, we will need the following components Īs usual, the exact components used for this tutorial can be gotten by clicking on the components above.
To achieve the goals of this tutorial i.e. 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. 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. * * Created by * * This example code is in the public domain * * Tutorial page: */ # include # define PIN_SPI_CS 4 File myFile int myInt = -52 float myFloat = -12.7 String myString = "HELLO" char m圜harArray = "ArduinoGetStarted.The Arduino Micro SD card Module is an SPI Communication based device.
