How to make a Line Follower Robot Car Using Arduino L293d and IR sensors (HELP/SUPPORT Provided)

[@abuchoudhury3958]

thankkyouuuuu so much , We were having mental breakdown because of the callibiration of that IR sensor , you dont know how much of a live savor you areee

🙏🙏👍👍👍👍 thanks for this lovely guidance

[@jumbo999614]

what is the distance between 2 sensors? I made my own sensor which is 3cm apart. How thick my black tape should be?

[@VARTHANTIME]

yes

[@jayq2571]

Amazing! Thank you for this especially this part 9:48

[@QuadStoreRobotics]

Great to hear that it was helpful for you :-)

[@3dgiftz]

I also made line following robot👏👏👏👏

[@QuadStoreRobotics]

Great to hear !

[@kavithasuresh4604]

What if sensor is not working pls reply i want it by tommorow

[@mariaknwal7304]

Can you please tell me if we can build this without the battery holder pin directly in arduino. I mean, I want to use the Motor Driver shield's external power Pins instead.

[@NoMoreErect]

why did it my robot stop when it detect the line and start making blinking sound

[@kasemalrpe4106]

L293D engine hood problem. Output voltage in m4. 7 volts, and the rest of the outputs are 2 volts

[@kavitadhiman8466]

Sir i m not able to upload the code there this robot doesn,t work tell me how to upload code

[@sirampavan6228]

Uh um got another problem it says after DC motor does not exist and error

[@DilipKumar-zp7ns]

@quadstore ,please help, when my right sensor detects black color, my left sensor detects as well( but my left sensor is not on a black line). The light goes off in both sensors , but only right sensor is on black line , and even my 4 wheel dont rotate backwards after detecting black surface , helppppp!

What type of battery should be used ? And how much voltage...?? Plz reply 🙏🙏

[@viharshpaharyapro8008]

Bro are you dumb ofcourse you will have to use branded AA batteries like Duracell Each having 1.5v each

i am having problems with my motors(they r working when directly connected)

Hey The code is not working. Can you guide me how to do it.

[@sreejaharikrishnan7182]

I don't know the codes

[@yaseenqureshi8717]

Name of the application?

[@abhayreddytigai]

Bro how much it costs to prepare it

[@vikramjeetpaul]

Sir can you plz attach a servo and an ultrasonic sensor in front of this car, so that when an obstacle is detected in front of the robot (while in the black line) then the ultrasonic sensor will rotate right and left (with the help of the servo ) and then avoid the obstacle and then move back to the track! IT WILL BE GREAT IF YOU CAN MAKE IT....PLZ!

[@QuadStoreRobotics]

OK we will try to make a video

Connections are the same. You just need to add 2 left side motors and 2 right side motors in series.
