How to manage the status light colors
The status lights show whether the robot is on and whether there is a program running. When the green light is on, the robot is turned on. When the green light flashes quickly, a program is currently running.
This is the default light behavior when we have not programmed it. From now on, if necessary, we can program it explicitly. The LED control unit is located in the green Action palette:
We can program the light
to switch on - ON mode,
to switch off - OFF mode,
or to return to flashing status as a normal operating program - Reset mode.

Robotics with LEGO - Level 3.0 - Security systems
This is the fifth level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.
In this level students will learn how to work with data measured by the sensors. The concept of Algorithm is introduced and the programs perform calculations without knowing the values beforehand. The programming blocks transfer data between each other via data wires. The robots are designed to address the problems of security systems. Variety of alarm systems are built and the physical principles of different security methods are considered.

Lesson 1 - Smart security plates
Introduction: Museum Security
Did you know that some pieces of art, for example statuettes, have a really high price, sometimes reaching millions of dollars/euros? This is one of the main reasons why such pieces of art are so tempting for robbers. In order to prevent them from being stolen, various alarm systems for museums and galleries have been developed over the years. Nevertheless, when one has a clear goal, one becomes exclusively crafty, especially when talking about robbers. In this lesson we are going to focus on various security devices and the ways robbers can be caught/ hacked. Will we manage to come up with the most secure system?
Today we are going to build security devices for a museum with highly valuable exhibits. The aim of our robots will be to detect whether there is an intruder in the museum hall and whether the exhibit is on its stand. For the purposes of our lesson, we are going to use a mobile phone or the robot’s brick as an exhibit.
Later, we are going to use the already programmed stand to play Indiana Jones and try to steal the valuable statuette without being detected. Then, we will move to something more practical – namely, we’ll try to automate a store.
