Introduction: LINE FOLLOWER ROBOT || ARDUINO CONTROLLED

IN THIS INSTRUCTABLE I SHOW HOW TO MODIFY A ROBOT CAR ( CARBOT) TO MAKE A LINE FOLLOWER ROBOT

Step 1: PARTS NEEDED

Picture of PARTS NEEDED

☻CARBOT REFER THE BELOW INSTRUCTABLE TO MAKE ONE

https://www.instructables.com/id/SIMPLE-CARBOT-ARD...

☻FEW JUMPER WIRES

☻IR SENSOR MODULE X 2

☻ BLACK TAPE

☻SOLDERING IRON

☻POWER BANK(JUST TO SAVE SOME BATTERIES

Step 2: SOLDER JUMPER WIRES

Picture of SOLDER JUMPER WIRES

SOLDER TWO WIRES EACH TO THE +VE AND -VE OF ONE OF THE IR MODULE AS SHOWN

Step 3: CONNECT THE IR MODULES TOGETHER

USE TWO JUMPER WIRES TO CONNECT THE +VE TO +VE OF THE IR MODULES AND -VE TO -VE OF IR MODULES, AS SHOWN.

Step 4: CONNECT THE DATA PINS

I USED AN ORANGE AND A YELLOW FEMALE TO MALE JUMPER WIRE TO CONNECT THE DATA PINS OF EACH OF THE IR MODULE

Step 5: HOT GLUE THE IR MODULE AS SHOWN

DO NOTE THAT THE MODULES STAY EXACTLY SIDE BY SIDE AS SHOWN

*ALSO HEIGHT FROM THE GROUND SHOULD NOT BE VERY LARGE

Step 6: CONNECT THE DATA PIN TO ARDUINO

CONNECT THE DATA PINS OF EACH OF THE IR MODULE TO PIN 5,6 RESPECTIVELY

Step 7: CONNECT -VE AND +VE TERMINAL OF THE ARDUINO

CONNECT -VE TO GND OF THE ARDUINO

CONNECT +VE TO THE +5V OF THE ARDUINO

Step 8: SEPARATE THE TWO MODULES

Picture of SEPARATE THE TWO MODULES

HOT GLUE A SMALL PIECE OF BLACK PAPER TO SEPARATE THE TWO IR MODULES FROM EACH OTHER

****REASON: IT IS DONE SO THAT THE IR RAYS FROM ONE OF THE MODULES DO NOT INTERFERE WITH THE PHOTODIODE OF THE OTHER

Step 9: CONNECT TO PC AND UPLOAD THE CODE

I built one of these for my 1st engineering degree final project in 2005. it used a pic microcontroller and 2 huge nema23 steppers. it followed metallic tape and ran around our whole lab. This is a cool little project

sounds cool :)
