Linefollower is a autonomous robot which followed a blackline on white surface. The robot uses IR sensor to sense the line. The output of the sensors is an analog signal which depends on amount of light reflected back; this analog signal is given to the comparator to produce 0s and 1s which then fed to the microcontroller .Using the truth table required logical program was fed in microcontroller which mapped input from three sensors to four output of L298 Motor Driver. Thus robot was able to follow the path with curves, break and parallax.

so you're saying that you're a robot? Can I ask questions in binary?
