-Whenever you perform a calibration curve, or want to read accurate values to the SD card, you should do so with the battery connected. Because of the differences in voltage applied by a computer through USB and the 9V batteries we are using, there is some variation in the voltage values read by the Arduino from each sensor. Keep this in mind! +Whenever you perform a calibration curve, or want to read accurate values to the SD card, you should do so with the battery connected.

For this lab, since you don't have an SD logger connected (yet!) just calibrate using the serial monitor through USB. Keep this in mind for future labs!
