Line Follower ROBOT Using Microcontroller AT89S2501
Award winner from VingPeaw Competition 2543, the robot built with microcontroller AT892051, IC H bridge L293D, and four IR sensors. Simple circuit and platform, quick tracking and easy-understand program using C language.Robot design use two motors control rear wheels and the single front wheel is free. It has 4-infrared sensors on the bottom for detect black tracking tape, when the sensors detected black color, output of comparator, LM324 is low logic and the other the output is high. Microcontrollor AT89C2051 and H-Bridge driver L293D were used to control direction and speed of motor. This project made by Plermjai Inchuay
