Set up and run experiment
If you wish to set up and run an experiment, start by clicking on the
Brick Datalog Settings button in the bottom right corner, symbolized
by a wrench. Use the Down and Right buttons to navigate to it and
the Centre button to click OK.
You can now decide the sample rate of your experiment, ranging
from one sample per minute to a thousand samples per second.
Use the Up and Down buttons to highlight Rate, then use the Left
and Right buttons to select the sample rate you wish to use for your
experiment.
Next, you can choose what sensor to use for your experiment.
Highlight Sensor Setup and click OK with the Centre button.
You will now get a list of sensors connected to your EV3 Brick. Use
the Up and Down buttons to highlight the sensor you want to use.
When a sensor is highlighted, use the Left and Right buttons to
select sensor mode (for example, whether the Colour Sensor should
measure colour or ambient light). Once you have found the correct
sensor mode, use the Centre button to click OK and you will be
taken back to the Settings screen. On the Settings screen, click the
check mark button and you are now back at the main EV3 Brick
Datalog screen.
To run your experiment, select and click on the Record button (next
to the Settings button with the wrench).
A live graph will now show the incoming values from the selected
sensor. To the right you can see the statistics of your experiment,
including duration. The flashing Record button and pulsing green
EV3 Brick Buttons Light indicate that your experiment is running. To
stop your experiment, click the Centre button.
When stopping your experiment, you will be asked to name your
experiment or accept the default name. Once you are done, click
OK and your experiment is now saved in the BrkDL_SAVE folder
that can be accessed from the File Navigation screen (please refer
to page 30).

NOTE:
The live graph is not
supported when logging data at
higher rates than ten samples per
seconds. The incoming values
will then only be shown
as numbers.
