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 6 - PIN code, Access codes
Introduction
