IDUINO for maker’s life

The Level Shifter moves all signals from 3.3 or 5V down to 3.3V so you can use this
shield with any Arduino safely and not damage cards. Cheaper shields use resistors to
level shift, but this doesn't work well at high speed or at all voltage levels!
The SD library, download from here https://github.com/adafruit/SD
Real Time Clock
This is the time-keeping device. It includes the 8-pin chip, the rectangular 32KHz
crystal, and a battery holder
The battery holder must contain a battery in order for the RTC to keep track of time
when power is removed from the Arduino! Use any CR1220 compatible coin cell.

Data logger
For using the data log function, you need the following parts to get this shield work.
Arduino (of course!) an Atmega328 type is best - we always recommend going
with an official 'classic' Arduino such as the Uno.
SD card formatted for FAT and tested using our example sketch
CdS photocell and a matching 10K pulldown resistor
Temperature sensor with analog out, such as TMP36
Battery pack such as a 6-AA 'brick' and a 2.1mm DC jack.
or you can use a 9V clip for a power supply but a 9V powered logger will last
only a couple hours so we suggest 6xAA's
Some 22 AWG wire, soldering iron, solder, etc.
About how to connect the parts, we can refer the Adafruit’s tutorial from here, but
remember, this shield have soldered the pins already,
