Datasheet

Build It!

Items you'll need:

Arduino (of course!) a Atmega328 type is best (http://adafru.it/50)- we always

recommend going with an official 'classic' Arduino such as the Uno.

Adafruit data logger shield (http://adafru.it/1141) - assembled

SD card formatted for FAT (http://adafru.it/102) and tested using our example

sketch (http://adafru.it/clN)

CdS photocell (http://adafru.it/161) and a matching 10K pulldown resistor

Temperature sensor with analog out, such as TMP36 (http://adafru.it/165)

Battery pack such as a 6-AA 'brick' and a 2.1mm DC jack. (http://adafru.it/248)

or you can use a 9V clip for a power supply (http://adafru.it/80) but a 9V powered

logger will last only a couple hours so we suggest 6xAA's

Some 22 AWG wire (http://adafru.it/c79), soldering iron, solder (http://adafru.it/doU),

etc.

You can get most everything in that list in a discounted pack in the Adafruit

shop! (http://adafru.it/249)
