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. The robot has two light detection sensors which are prepared with LDRs (light dependent resistors). It has two 6 V geared DC motors, two wheels and a caster ball wheel. Light following robot was powered only by 3 AA alkaline batteries. PIC16F628A was used as microcontroller for the robot. The motor control part of the circuit was prepared with two BDX53 darlington transistors.
