can you save data to a database ?

is it possible to connect the arduino to a hard disk and save data to a database / text file ?

It is possible to save data directly to a micro-SD card from an Arduino. It would also be possible to transmit data over serial/ethernet to a server that stored that data in some format as well.

Check - http://code.google.com/p/sdfatlib/ - the sd fat library

especially for logging is this shield - Data-Logger Shield for Arduino -

it adds a RTC RealTime Clock so you can timetag your samples.

awesome - that is going to be sooooo handy

cheers
