Serial.println(volume.blocksPerCluster() * volume.clusterCount()) Serial.println(volume.blocksPerCluster()) Serial.println("Could not find FAT16/FAT32 partition.\nMake sure you've formatted the card") Now we will try to open the 'volume'/'partition' - it should be FAT16 or FAT32 Serial.println("Wiring is correct and a card is present.") Serial.println("* did you change the chipSelect pin to match your shield or module?") Serial.println("* is your wiring correct?") since we're just testing if the card is working!

Open serial communications and wait for port to open: set up variables using the SD utility library functions: Interfacing Arduino with SD card example (get SD card info) I got the code below from arduino examples (with minor modifications), it collects information about the SD card connected to the Arduino and print it to Arduino IDE serial monitor. The SD card MISO is connected directly to the arduino because this path is used by the SD card to send data to the arduino (with voltage of 3.3V).Ĭonnecting the SD card directly to the arduino without voltage level converters or voltage dividers may damage it. The Arduino sends these signals from pins 13, 11 and 10 respectively.

The voltage dividers are used for SD card signals: SCK (serial clock), MOSI (master out slave in) and SS (chip select). In the circuit there are 3 voltage dividers, each one consists of 2.2K and 3.3K resistors, they are used to step down 5V that comes from the arduino into 3V which is sufficient for the SD card signals. The SD card is supplied from the Arduino board with 3.3V. (Grounded terminals are connected together)

SD card with FAT16 or FAT32 file systemĮxample circuit schematic diagram is shown below.

This can be the hardware SS pin – pin 10 (on most Arduino boards) or pin 53 (on the Mega) – or another pin specified in the call to SD.begin(). Additionally, another pin must be used to select the SD card. The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). The library supports FAT16 and FAT32 file systems on standard SD cards and SDHC cards. It is built on sdfatlib by William Greiman. The Arduino SD library allows for reading from and writing to SD cards. Also Proteus simulation of the Arduino and SD card is available with a small video.Īrduino has a very nice SD card library, with this library the interfacing is very simple.

The example reports volume type, free space and other information using the SD library, sending it over the serial port.

This example shows how to read information about a SD card. This topic shows how to get started with Arduino and SD card (microSD cards).
