This final thesis will follow the making of an Arduino programmable robot, Arduino itself, the way it works, its capabilities and its use in modern tehnology in detail. The main task is to solve the practical problems of building robots for line following. Line follower robot is designed to move on a particular line and provides an alternative practical opportunity for instructors as well as for students to enrich the teaching and learning experience. This paper aims to help readers build line follower robot using open-source platform based on simple hardware and software – Arduino.
