IR LINE FOLLOWING ROBOT USING IR SENSOR ARRAY(8 INPUT) AND L293D MOTOR DRIVER

Introduction: IR LINE FOLLOWING ROBOT USING IR SENSOR ARRAY(8 INPUT) AND L293D MOTOR DRIVER

About: keep going forward , God Sees the Truth, But Waits

"My line following robot after making ,YOU can also make your own robot simply "



Step 1: Our Brain for Line Following Robot Is Arduino Nano

(its program methodology and pin configuration are same arduino uno (bcoz both contain Atmega328p) ,connect battery to VIN pin of aduino and take regulated 5v from 5v pin and it supply to IR SENSOR and motor driver's 16th pin

Step 2: ​IR Sensor Array

IR sensor array contain 8 IR LED and 8 IR SENSOR also it have two mode of output

1) analog output (direct analog data from ir sensor ) 2) digital output ( using linear voltage comparator with potentiometer)

Step 3: Motor Driver

Motor driver designed using L293D motor driver IC it give smooth operation and required fast output working together with arduino nano.

you can buy this module type of this ic from any market price will be less than 120 indian rupees

( or)

you can make your own board , i also attached the gerber file for making PCB board for L293D

Step 4: Gear Motors

100 RPM motors are used it this robot ,

Step 5: Battery for Line Following Robot

4 AA Battery used for running our robot , arduino nano have voltage regulator therefore it convert battery voltage into 5v give,this regulated 5v to motor driver's 16th pin for logic operation of motor driver ic L293D

Step 6: Wiring and Simulation ( Proteus Professional )

you can also simulate this design and study the working

    Question 3 years ago on Step 2

    What is the distance between teo consecutive IRs in the array?
