Mini Arduino light follower robot is a mobile robot which detects the light (such as the light of a flashlight) and follows the light on the travelling path.

Arduino Uno R3 is used as the controller board of the light follower robot.

The robot has RS Arduino Uno Shield which contains the input / output headers, on/off switch and a L293D motor driver on it.

Two light sensor modules are used for tracking the line.

Robot chassis is prepared with 3 mm thick plexiglass material.

The robot has two 6 V 150 rpm geared DC motors, two wheels and a caster ball wheel.

Mini Arduino light follower robot is powered by a 9 V alkaline battery.
