 Il codice è l'adattamento del codice SD datalogger e del codice RTC by zappoco 2019
 
 SD card datalogger

 This example shows how to log data from three analog sensors
 to an SD card using the SD library.

 The circuit:
 * analog sensors on analog ins 0, 1, and 2
 * SD card attached to SPI bus as follows:
 ** MOSI - pin 11
 ** MISO - pin 12
 ** CLK -  pin 13
 ** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)
