Is it possible to make somthing out of the void loop() ? etc. somthing like "void writeSd()", that can save data to a SD-card. If that is possible, how do i call the WriteSd() from the loop, ONLY one time??. I my mind it is not nessecary to read the whole loop, when the program has to write to the SD-card, ect. every 10 minutes. This will only cost on the performance.
Sorry for my bad english, but this is a fantastic help-site, for learning.
