here the Line follower robot follow the black line on the white surface with the help of two different sensor. Both the sensor sense the black line and if the sensor is on the white surface then robot slightly changes its position and again follow the black line

What is a line follower?
Line follower is a machine that can follow a path. The path can be visible like a black
line on a white surface (or vice-versa) or it can be invisible like a magnetic field.
Why build a line follower?
Sensing a line and maneuvering the robot to stay on course, while constantly correcting
wrong moves using feedback mechanism forms a simple yet effective closed loop
system. As a programmer you get an opportunity to ‘teach’ the robot how to follow the
line thus giving it a human-like property of responding to stimuli.
Practical applications of a line follower : Automated cars running on roads with
embedded magnets; guidance system for industrial robots moving on shop floor etc.
Knowledge of basic digital and analog electronics.
(A course on Digital Design and Electronic Devices & Circuits would be helpful)
Sheer interest, an innovative brain and perseverance
The resistance of the sensor decreases
when IR light falls on it. A good
sensor will have near zero resistance
in presence of light and a very large
resistance in absence of light.
We have used this property of the
sensor to form a potential divider.
The potential at point ‘2’ is
Rsensor / (Rsensor + R1).
Again, a good sensor circuit should
give maximum change in potential at
point ‘2’ for no-light and bright-light
conditions. This is especially
important if you plan to use an ADC
in place of the comparator
