Video sam vas post na YouTube kanalu o SPI vezi i DHT11, da ne bih prepisivao sa ekrana nasao sam ovaj kod i Arduino IDE ga je dobro uplodovao na Croduino Basic2
Medjutim, SD kartica nece da se inicijalizuje, proverio sam i MISO i ostale (prema uputstvu sa vaseg YouTube kanala) i mislim da sam sve dobro prikacio.
Svaka sugestija je dobrodosla

// Arduino data logger with SD card and DHT11 humidity and temperature sensor
#include <SPI.h> // Include SPI library (needed for the SD card)
#include <SD.h> // Include SD library
#include <DHT.h> // Include DHT sensor library
File dataFile;
#define DHTPIN 4 // DHT11 data pin is connected to Arduino pin 4
#define DHTTYPE DHT11 // DHT11 sensor is used
DHT dht(DHTPIN, DHTTYPE); // Initialize DHT library
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial)
; // wait for serial port to connect. Needed for native USB port only
Serial.print("Initializing SD card...");
if (!SD.begin()) {
Serial.println("initialization failed!");
while (1);
}
Serial.println("initialization done.");
delay(2000);
}
uint16_t line = 1;
void loop() {
delay(1000);
// Read humidity
byte RH = dht.readHumidity();
//Read temperature in degree Celsius
byte Temp = dht.readTemperature();
dataFile = SD.open("DHT11Log.txt", FILE_WRITE);
// if the file opened okay, write to it:
if (dataFile) {
Serial.print(line);
Serial.print(": Temperature = ");
Serial.print(Temp);
Serial.print("°C, Humidity = ");
Serial.print(RH);
Serial.println("%");
// Write data to SD card file (DHT11Log.txt)
dataFile.print(line++);
dataFile.print(": Temperature = ");
dataFile.print(Temp);
dataFile.print("°C, Humidity = ");
dataFile.print(RH);
dataFile.println("%");
dataFile.close();
}
// if the file didn't open, print an error:
else
Serial.println("error opening DHT11Log.txt");
}
