Tutorial: How to use Stackable SD Card

This expansion board allows you to read and write to an SD card, ideal for projects that require data storage. Suitable for beginners and intermediates.

What you need

• Arduino
• SD Card
• Duemilanove cable
• 10kΩ resistor

Steps

1. 1. Installation: Download and install the SD library for Arduino.
2. 2. Connection: Connect the SD card to the stackable card.
3. 3. Connection: Connect the stackable card to your Arduino.
4. 4. Connection: Connect the 10kΩ resistor between VCC and GND of the stackable card.
5. 5. Code: Copy the minimal code to read and write.
6. 6. Upload: Upload the code to Arduino.
7. 7. Test: Insert an SD card and verify read and write operations.
8. 8. Covering: Cover the SD card with the provided cover.

Example code

```void setup() {  SD.begin(4);  // Inizia la comunicazione con la scheda SD}void loop() {  // Codice per leggere e scrivere su scheda SD}```

Mini project

Create a temperature log using a temperature sensor and the SD card.

Common mistakes

• Connect the 10kΩ resistor only between VCC and GND of the stackable card.
• Check the datasheet to see if your SD card supports SPI communication.
• Make sure the SD library is correctly installed.
• Check the correct connection of the pins.

Recommended accessories

• Temperature sensor
• Cover to protect the SD card
• Duemilanove cable
• 10kΩ resistor
