How to Make DIY Arduino Line Follower Robot Car with Arduino UNO, L298N Motor Driver, IR Sensor

[@MakeDIY9]

Here is the code Link: bit.ly/38eYHYK Enjoy :)

[@syaduinotech3681]

Dear sir.. thanks for the code. The "amp" error appear. Can you help why? And how to solve that?

[@MakeDIY9]

Please try it one more time

[@kittyawn5317]

does your code need additonal lib? cuz the `&amp` doesnt declared yet seems like you mean ` && ` (and logic gate)

can you put the coding of this car

[@talentexamwinner4733]

THANK YOU BRO!For my science exhibition, I made a line follower robot based on your vidio . I followed your methods. Finally I did it! And I got first price! GOD BLESS YOU ❤️

[@cjsiam8672]

did you know arduino programing from early on?

[@rimmykathuria]

Its not working

[@rimmykathuria]

Don't make us fool

[@gamersyt2661]

Exactly what I was looking for. No need of opening the serial monitor, just simple calibration and you are good to go. Thank you so much for the video. Subbed!

[@MakeDIY9]

Great to hear!

[@snitch_fn7428]

How does the car move left and right based on IR sensors? Can you explain please

[@mishagupta9435]

had trouble finding circuit in other youtuber car but you gave the circuit thanx alot thankyou

Hi if we use powerbank instead of batter will the car move..?

[@Pavara_Senvidu]

Can we fix a 9v battery instead of that 2 rechargable batteries??

[@Adi_creator71]

Yes bro u can but less than 20v

[@herambkadam8693]

Heyy can you share the circuit digram please. Btw superb explanation and great work . Thankyou

[@TUANFATINNABILAHBINTITUANPA]

what should we check if only left tyre is moving while the right one is not? both sensor detect but only the the left one is function

[@muhammedashikch8461]

Sir this line following robot is followong a black line . Instead of black line can i put red or other colour line to this robot???

[@rjreyaan9856]

Excellent and quality content , Dear can you please tell me how to run this car smoothly at lower speed .. No battery drain issue and no lags on motors.. hope u getting what m trying to say ..

Thanks Man 😄

Hey bro i make this type of robot for my college project but the problem is when i start the robot it will go straight very easy but when he try to turn it will stuck what can I do please help

[@KrishnaveniD-t5q]

Hi, could you upload the sketch for the program because I need it for my science exhibition

[@malekabdoh8639]

loved the video most detailed one I could find but the only thing I dint like was that he didn't speak in the video to explain it

[@MakeDIY9]

Check the article link bro

[@luckshaeey]

Video quality is so good. I Appreciate it ♥️ thanks for putting this video out on the internet for confused souls like me.

[@MakeDIY9]

Glad you enjoyed it!

[@luckshaeey]

I had a doubt. When Im using those cheap 9V battery my motors aren't powering up. Have checked all the connections and code. When instead i used L293D motor driver my bot runs like butter with the same power supply. Can you tell me what could be the probable reason?

[@MakeDIY9]

battery bro... 9V battery issue. Previously I tried to make the car with the 9V battery but it doesn't provide enough power to the car to run. so I stuck with Li-ion battery for high Power....

[@luckshaeey]

@@MakeDIY9 ok. But i switched to l293 driver only. L298 for some reasons was messing with my project. 😐

[@MakeDIY9]

@@luckshaeey I will make a version of this car with l293d

[@Nothing-rm5sy]

@@MakeDIY9 bro is obstacles avoiding and line following are two different ir sensors? Because i made full car as per your connections but still doesn't moving Motors are not running can you tell me what would be problem (i have used 18650 li-ion battery)

[@keshavsharma4596]

bro can you give me the link of the app that you used to control the robot by bluetooth🙁

[@itssouravvv]

Hey brother, my car has little weight on it what should i do it’s not moving

[@fouzanjaved5441]

Sir, I like your videos about Arduino projects. Sir, will the line follower robot sensors blink and produce the sound beep when completing the black line circle if I attach the 5v buzzer in the circuit diagram as well in the code for the line follower robot? Sir, will the line follower robot work or not?

[@raptorthegamer5524]

The code needs to know the start and end points of the circle, otherwise it won't work

[@sarihardianti9903]

the car is starting and the wheels are turning but it won't move on the track, can you help me how to solve it?

[@maskb2k876]

Can we do the same with aurdino nano

[@nkumaragarwal]

Could you please provide the link for GND and +5v wire

[@jayanthreddy3972]

what happen is any object is interrupts in middle of the line , is it stop?

[@PrafulTheExplorer]

Hello And Thanks for sharing this tutorial. One question- Is there a way to use IR module and IR remote instead of a switch. So it can be used to start the robot wirelessly and can be stopped whenever required from the IR remote. ? Please guide on this

[@anandvaibhavsingh6954]

Could you please tell me which motor driver woul be best and why? because I have to write about it

[@MakeDIY9]

L293D easy to control L298N high current output

[@CHIEFSWAGGER]

But sir what we should do to increase the speed of car?

[@HarshGArt]

[@DianaSirbu487]

Hi Do you have any ideea why neither of my wheels are working at the forward movement but at the turns they work perfectly fine? Thanks

[@MakeDIY9]

Check your motor driver first

Thank You So much SIR !! It was really really Helpfull 🖤🖤💯

[@palakthareja2257]

Hii I tried the same everything is fine the connections code etc but after uploading the code the car just doesn't move. Can you tell what can be the reason for this?

[@anonymous15042]

[@akshat7787]

can we make it with L293n motor driver

[@isabelletroya5967]

My car isn't turning, should I change the speed? Also could you explain what M1 and M2 speed means along with what speed specifically I should change?

[@MakeDIY9]

Calibrate the car carefully and check the ir sensor first. You have to manually calibrate as I have shown in the video M1 left side motors M2 right side motors

[@onelife4458]

You are very creative 👍❤️❤️❤️

when I'm testing only 3 tyres are moving and when I turn counter clockwise , no tyre moves and when I turn clockwise only 1 tyre very slowly moves. And When I keep one clockwise and one sensor anti clockwise then 3 tyres move and ny car moves in a circle I have changed sensor also .

Bro which is better l293d or l298n

[@MakeDIY9]

If you ask me l298n is better because of high power count. But however I will also make a robot tith l293d also 😉

Ok bro ☺️

Could one be built to have stop points for pick up or drop off of goods? You would have a remote or button panel with up to 10 way points maybe?

Bro will you please upgrade this to go through a line stop at the end for some minute then return back

Are you from India

[@chiragsr6757]

Working but only for straight path Not taking turn wat 2 do

[@MakeDIY9]

You have to adjust the sensor and the motor speed. I have used 150rpm motor for the video lin lower speed. Which rpm motor you are using? Tips: 1. Try using lowering the rpm in the code by changing the speed value to 0 to 255. 2. Try to adjust the sensors.
