AT89C2051 based Line Follower ROBOT

A Line following robot is the most popular beginner's choice in the world of robotics. Here is one that is controlled by a AT89C2051 microcontroller. It uses two motors that control the two rear wheels and the front wheel is free. The four infrared sensors detects a black track on floor that helps the ROBOT to follow it. LM324 IC (H-bridge driver) is used to compare the voltages from the IR sensors and L293D is used to drive the motors.

Firmware for AT89C2051 is written in C.
