How to interface SD or Micro SD cards with Arduino?

I want to create a temperature logging circuit which will store its temp. readings every minute. I would like a detailed reply plz.

What have you tried? What SD shield do you have? What temperature sensor? What clock?

The Adafruit folks seem to have a great new shield containing a SD reader/writer/logger and a built in real time clock, all assembled for just $20. Seems to have tested library support, hard to see a better solution for the price, I may have to pick one up myself. http://www.adafruit.com/products/1141

@John and Lefty. That does look like a nice unit, but it appears to be incompatible with the Mega, and that is what I use. There is no ICSP socket to connect the SPI data lines. :(

This is from that page.

Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported.

I'm not sure how it can be Leonardo and Mega compatible without the ICSP connector. Maybe you need jumpers to digital pins 50-52 or the ICSP connector?

On the Mega you use "Soft SPI" on pins 10-13. http://forums.adafruit.com/viewtopic.php?f=31&t=24867

Thanks John. So I guess what they mean is:
If you use the Adafruit SD library with the Mega and Leonardo, it will work.
If you use the standard Arduino SD library with them, it will fail.

I will believe it, but wouldn’t buy it.

SdFat has a soft SPI mode and I wrote soft I2C libraries so the AdaFruit Shield can be used on Mega, Leonardo, and 328 Arduinos.

Here is an example sketch and the libraries - AdafruitLogger20121219.zip http://code.google.com/p/beta-lib/downloads/list.

The previous version plus this version of the sketch and libraries have been downloaded over 1000 times.
