Datasheet

Upload the sketch to your Arduino. We'll now test it out while still 'tethered' to the computer

While the Arduno is still connected, blinking and powered, place your hand over the

photocell for a few seconds, then shine a flashlight on it. You should also squeeze the temp

sensor with your fingers to heat it up

Plotting with a spreadsheet

When you're ready to check out the data, unplug the Arduino and put the SD card into your

computer's card reader. You'll see a at least one and perhaps a couple files, one for each

time the logger ended up running

We'll open the most recent one. If you want to use the same logfile used in the graphing

demos, click here to download it (http://adafru.it/cny).

The quickest way to look at the data is using something like OpenOffice or Excel, where

you can open the .csv file and have it imported directly into the spreadsheet
