for a project I need to store values. I searched the forum and playground etc. and think the uFat solution is the best for me (small footprint but still readable on a PC).
However I have questions (beeing a noob :-? in such things)
How do I compile this? I tink not in the arduino IDE?
(1) The library you linked is put in its own directory under the Arduino toolset, like hardware/libraries/uFat. This lets the IDE find it, compile it as necessary, and incorporate it into your Arduino sketch program.
(2) There are a couple Arduino shields (daughter-boards) that incorporate an SD card slot holder component, and these are routed appropriately to some digital I/O lines of the Arduino.
One example is the Adafruit Wave Shield, pictured below. There are others. It's not easy to use without soldering to a printed circuit board, however.
