The document summarizes the components and functioning of a line following robot. It consists of an Arduino board as the brain, two IR sensors to detect the line, a motor driver IC and two DC motors for movement. The IR sensors detect the line and send signals to the Arduino, which uses the motor driver IC to control the motors' direction - forward when both sensors detect the line, right when the left sensor doesn't, and left when the right sensor doesn't. Key components are the Arduino, IR sensors, motor driver IC and DC motors.

2. What is a ROBOT?
A machine that
works automatically
and can do some
tasks that human can
do.

3. What is an LINE FOLLOWING ROBOT?
It is an autonomous robot
Which follows
black line in white area
OR
White line in black area.
A robot must be able to
detect particular line and
keep following it is called
line following robot..

4. Requirements:
Jumper wires
Dc motor
IR sensor
ARDUINO
WHEELS

5. Block diagram of Line Following Robot

6. It is an open source electronic
platform to read inputs-light on a
sensor, a finger on a button –and
turned into a output –activating a
motor or turning on an LED and
probably it has been the brain of
1000’s of projects

9. L293D / H-BRIDGE

10. A motor driver which is arranged in rows called H-BRIDGE.it
is an electric circuit which enables a voltage to be applied across
a load in either direction.
L293D is a dual H-BRIDGE
motor driver INTEGRATED CIRCUIT (IC)
These motor drivers act as a circuit amplifier since they take
Low current control signal and provide a high current signal
This high current signal is used to drive the motors
