LEARNING POWERED BY LEGO®MINDSTORMS®EDUCATION
Since the beginning of this century, LEGO
®
MINDSTORMS
®
Education
has led the way in STEM (Science, Technology, Engineering, and
Math) Education, inspiring users to engage in fun, hands-on learning.
The combination of LEGO building systems with the LEGO
MINDSTORMS Education EV3 technology is now offering even more
ways to learn about robotics and teach the principles of programming,
physical science, and mathematics.
The heart of LEGO MINDSTORMS Education is the EV3 Brick, the
programmable intelligent brick that controls motors and sensors,
as well as providing wireless communication. Choose what motors
and sensors you wish to use and build your robot just how you want
it to be.
To provide the interface between you and the EV3 Brick, we have
developed the LEGO MINDSTORMS Education EV3 Software and
EV3 Programming App. The EV3 Software for Windows and
Macintosh gives you easy access to content, programming, data
logging, digital workbooks, and more, while the EV3 Programming
App gives you many of the same features on a Chromebook or
tablet. Follow the integrated Robot Educator tutorials and you’ll be
creating, programming, and running your robot before you know it.
The intuitive, icon-based Programming Environment is full of
challenging possibilities, and the EV3 Software’s data logging
environment provides a powerful tool for scientific experimentation.
LEGO Education offers a growing number of EV3-based curriculum
packages developed by experienced educators. We are committed
to responsive customer support, professional development, and
continuing education for teachers using MINDSTORMS robotics in
their classrooms.
Want to work like real scientists and engineers? Enter the LEGO
Education-supported FIRST®LEGO League and World Robot
Olympiad – and gain invaluable knowledge, life skills, and increased
self-confidence!
We hope you enjoy the journey!

Overview
The Display shows you what is going on inside the EV3 Brick and
enables you to use the Brick Interface. It also allows you to add
text and numerical or graphic responses into your programming or
experiments. For example, you might want to program the Display
to show a happy face (or a sad face) for a comparison response or
to display a number that is the result of a mathematical calculation
(learn more about using the Display Block in the EV3 Software Help).
The Brick Buttons allow you to navigate inside the EV3 Brick
Interface. They can also be used as programmable activators. For
example, you might program a robot to raise its arms if the Up button
is pressed or to lower them if the Down button is pressed (for more
information, see Using the Brick Buttons in the EV3 Software Help).

The Brick Status Light that surrounds the Brick Buttons tells you the
current status of the EV3 Brick. It can be green, orange, or red and
can pulse. Brick Status Light codes are the following:
+Red = Startup, Updating, Shutdown
+Red pulsing = Busy
+Orange = Alert, Ready
+Orange pulsing = Alert, Running
+Green = Ready
+Green pulsing = Running Program
You can also program the Brick Status Light to show different colours
and to pulse when different conditions are met (learn more about
using the Brick Status Light Block in the EV3 Software Help).

Installing Batteries
With LEGO®MINDSTORMS®Education EV3, you have the choice of
using normal AA batteries or the EV3 Rechargeable Battery pack
included in the LEGO MINDSTORMS Education EV3 Core Set. If you
experiment with both, you will find that each option has characteristics
to consider when constructing your robots. For instance, six AA
batteries weigh more than the Rechargeable Battery, and the EV3 Brick
with the Rechargeable Battery installed is slightly larger than the
EV3 Brick with six AA batteries.
The EV3 Rechargeable Battery is a convenient and economical
alternative to using AA batteries. It can be recharged while inbuilt
in a model, saving you the trouble of disassembling and reassembling
a robot to replace batteries.
To install the Rechargeable Battery on the EV3 Brick, remove the
battery cover on the back of the EV3 Brick by pressing the two
plastic tabs on the side. If there are batteries in the EV3 Brick,
remove them. Insert the Rechargeable Battery in the slots that held
the battery cover in place and snap the battery in place. The battery
cover is not used.
If it is your first use of the battery – or if the battery is completely
drained, let the battery and the EV3 Brick charge together for at
least twenty minutes.
Using the enclosed power adaptor cord, connect the Rechargeable
Battery to a wall outlet. Make sure to keep the transformer cord and
battery where they will not be tripped over or get wet.
When you plug the uncharged battery into a wall socket, a red
indicator light will be lit. When charging is complete, the red light
will go out and the green light will be illuminated. The recharging
process will generally take three to four hours. If you use the EV3
Brick while the battery is charging, it will take longer. Before you
start to use the Rechargeable Battery for the first time, it is
recommended that it is fully charged.
