 There is a delay statement at the end of the loop.  Think about how many data points will be taken if you take data for 5 minutes.  Will you need data this often?  More often?  Less often?  Adjust the delay accordingly.

 While power is disconnected from the Arduino, go ahead and insert the microSD card into the adapter module. Plug in the Arduino (to USB), connect the 9V battery, and open the file at File -> Examples -> ENGR100-950 -> Lab3-SDtester and upload/run it. This script will throw an error statement in the serial monitor if the SD logger is not working properly. Once this script runs and appears to have worked for a few moments, go ahead and disconnect power, remove the SD card, and open the contents on your computer. You should see a file titled `DATALOG.CSV` which should be a CSV file with sample headers (names of the sensors we are using) and rows of data that are numbered 0-7 for each column. If this appears correct, then congratulations, you have successfully connected your SD logger and you are ready to meet up with Group B once they have finished their part! Make sure to clear this SD card and empty the trash!

-When Group B is ready to move on, take both of your breadboards and move all the jumpers running from their Arduino into the same pins on your Arduino, so that everything is wired into one microcontroller (you need not physically move the components, but rather just their jumpers, leaving two breadboards side by side. They can lock together!). Once this is done, follow the link below to jump back into the normal lab manual together.

They can lock together!). Connecting these breadboards is best done by moving ONLY the analog jumpers from Group B's Arduino to Group A's Arduino, and then connecting a jumper from the 5V rail of Group A to the 5V rail to Group B (do this for the 3.3V rail and the GND rails as well). As one last final check, Group B's original Arduino should have nothing plugged into it, so you can remove any jumpers remaining for power or GND.
