BRICK DATALOG

The EV3 Brick comes with a simple-to-use, on-brick data logging

application. These instructions provide you with the basic information

you will need to get started.

Main screen

When you open the EV3 Brick Datalog app, you will see to the left

a Graph Area. If a sensor or motor is connected to the EV3 Brick,

a graph will show live readings from one of the sensors like an

oscilloscope (if a motor is connected, it is readings from the in-build

rotation sensor).

To the right of the graph, the following numbers are displayed (from

the top): actual reading, duration, highest reading, lowest reading,

and average reading. Duration will only be shown when running an

experiment—not when in Oscilloscope Mode.

Underneath, a small window will indicate what port the values are

currently read from (Input Port 1, 2, 3, or 4, or Output Port A, B, C,

or D). To change the port, use the Left and Right buttons to click

through the available ports.
