• Environmental variable monitoring
• Data collection for subsequent analysis

Tutorial: How to use Logging Shield

The Logging Shield is an Arduino module that allows data recording on an external memory. Useful for projects that require real-time data logging.

What you need

• Arduino
• MicroSD Card
• USB Cable
• MicroSD Card Reader (optional)

Steps

1. 1. Installation: Download and install the SD library for Arduino from the Arduino repository.
2. 2. Connection: Connect the Logging Shield to your Arduino using the following connectors: VCC to 5V, GND to GND, SDA to SDA, SCL to SCL.
3. 3. Insert the MicroSD Card into the dedicated slot on the Logging Shield.
4. 4. Upload the example Sketch code to your Arduino.
5. 5. Configure the file name and write frequency in the code.
6. 6. Run the code and check the folder of swap directories for the presence of the log file.
7. 7. Turn off the Arduino and remove the MicroSD Card.
8. 8. Read the data with a MicroSD Card reader (optional).

Example code

```cpp
#include <SD.h>

File myFile;

void setup() {
  Serial.begin(9600);
  if (!SD.begin(4)) {
    Serial.println("Card failed, or not present");
    return;
  }
  Serial.println("Card initialized.");
  myFile = SD.open("log.txt", FILE_WRITE);
  if (!myFile) {
    Serial.println("Errore apertura file");
    return;
  }
  Serial.println("Scrivo nel file");
  myFile.println("Hello, world!");
  myFile.close();
  Serial.println("File chiuso");
}

void loop() {
  // Nessuna logica qui
}
```

Mini project

Create a temperature sensor that logs data to a MicroSD Card every 5 minutes.
