INTRODUCTION
Line follower robot using microcontroler
A line follower is basically a machine designed to follow a path predetermined bythe user. The path maybe as simple as a straight or a curved line or it maybe as
complex as a 90 degree turn and junction counting capabilities. In our semester
project, we will concentrate on simple tasks.
Line follower robot can detect bright light using specific sensors, and de fine its
motion accordingly. Line follower senses the line using its sensors and
maneuvers the mechanical structure to stay on course while constantly correcting
wrong moves.
The correct positioning of the sensors presents a feasible controlling strategy for
complex as well as simple tasks. A robot will know when to turn depending on the
location of the sensors. Number of sensors determines the smooth movement of
the robot. Optimum distance between the sensors depends on number of sensors,
width of straight line and the logic applied

CIRCUIT DESCRIPTION OF LINE FOLLOWER
ROBOT
This line follower robot is design by basic microcontroller (8051). Microcontroller
is the heart of the embedded design. Output is obtained from port1 at which
7segmnt is connected and port2.4, 2.5, 2.6, 2.7 at which DC motor IC(L293D) is
connected as shown in circuit diagram. To play this remote control vehicle switch
swf , swb,sws are placed in on position (or pushed) port3. But when we press
switch swf motor will move in forward direction and when switch swb is pressed
motor will move in reverse direction otherwise when sws is pressed it is in stop
condition. when we press switch swf then F is display on 7segment or when we press switch swb then B is display on 7segment or when switch sws is pressed
then S is display on the 7segment.
