Microcontroller Monday Read and Write to an SD card with Arduino
A standard microSD card has an operating voltage of 3.3 V. As a result, we cannot connect it directly to circuits that use 5V logic; in fact, any voltages above 3.6V may permanently damage the microSD card. That is why the module includes an onboard ultra-low dropout voltage regulator capable of regulating voltage to 3.3V.
Arduino micro SD Card Data Logger
Pinout Micro SD Card Module includes 6 pins: VCC pin: connect to the Arduino's 5V pin. GND pin: connect this pin to the Arduino's GND. MISO pin: (Master In Slave Out) connect this pin to the Arduino's MOSI pin. MOSI pin: (Master Out Slave In) connect this pin to the Arduino's MISO pin. SCK pin: connect this pin to the Arduino's SCK pin.
How to Use an SD Card With Your Arduino Arduino Maker Pro
Connecting the SD-card module to Arduino. After preliminary preparation of the SD card, we can begin to connect the microSD and Arduino expansion board. The expansion card makes the connection much easier. It has a regulator that converts the voltage of 3.3 - 6 V to 3.3 V (I2C).
Arduino SD Card Reader Technology Tutorials
Using the SD Card. The other half of the data logger shield is the SD card. The SD card is how we store long term data. While the Arduino chip has a permanent EEPROM storage, its only a couple hundred bytes - tiny compared to a 2 gig SD card. SD cards are so cheap and easy to get, its an obvious choice for long term storage so we use them for.
