EV3 Brick Interface

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 Center 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 Center 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, if the Color Sensor should

measure color or ambient light). Once you have found the correct

sensor mode, use the Center 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 Center 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 (see page 25).
