Arduino sd card tutorial deutsch

This Micro SD Card is used weil das transfering dünn to und from a typical sd card. Die pin out zu sein directly compatible with Arduino and so can be provided with other microcontrollers. It enable us zu add fixed storage and data logging zu our project.

Features

Input Voltage: 3.3V/5V through all SD SPI Pins out :MOSI, SCK, MISO und CS ,for further link Through programming, you kann read und write to ns SD card making use of your arduino Make her SD application more easier und simple communicate with Arduino utilizing SPI user interface Push-pop socket through card contempt over die edge des the PCB deswegen its easy kommen sie insert und remove 4 mounting holes with 2.2mm diameter just use 4 I/O pins on ns Arduino Size: 42mm x 25mm ns 5mm

Micro SD map Module

This module uses ns standard SPI interface zum communication, i m sorry involve SPI buses, MISO, MOSI, SCK, und a CS signal pin. With programming, ns data kann easily be read und wrote right into SD Card by using the Arduino or other microcontrollers.

CS (chip select)SCK (serial clock)MOSI (master out slave in)VCC (3.3V or 5V)GND (ground)

Diagram over shows ns simple connection between Micro SD card Module und Arduino UNO:

Connect VCC v 5V in the Arduino.Then, connect ns GND of SD map to ns ground des Arduino.Connect CS kommen sie pin 14Connect SCK to pin 13MOSI attach to die pin 11Lastly, affix MISO zu pin 12

After completing die connection, connect the Arduino to power supply with USB cable.

The adhering to result will be displayed in the monitor. An this example, ns .txt paper named "test.txt" was created und the sentence "testing 1,2,3." were composed into die .txt file. After this, ns sentence "testing 1,2,3." were read back from .txt file und display ~ above serial monitor.

Hi, thank freundin very much zum this posts, it ist very interesting weil das me. But I have a question around how zu read from SD card. Zum example, I have number 3 and I write zu SD card as soon as every minute. How kann I get data at any type of point in time?


Hey,myFile = SD.open("test.txt"); if (myFile) Serial.println("test.txt:"); while (myFile.available()) Serial.write(myFile.read()); myFile.close(); rather Serial.println("error opened test.txt");return; that have to work. What ns code is doing is that the will zuerst open die file, climate it wollen chack if that document existes. Then it wollen go v every char an the file und print it on the serial monitor.Bust von luck,Electronics_boy
