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)

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 ❤️

did you know arduino programing from early on?

Its not working

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!

Mare ir sensor me 4 pins hai connection kayse karu samazme nahi aaraha hai please help me🙏😭

[@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. 😐

do we need to change the code according to the path???? or this code is set for all path?

[@TheHappyfeet227]

It's working but the problem is that when both sensor reads 0 and 0, only the right part of the wheels is working and the left does not. But when turning left or right, all 4 wheels are working. What seems to be the problem?

[@maskb2k876]

Can we do the same with aurdino nano

[@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?

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

[@noobmaster6074]

How to control each motor individualy?

[@anonymous15042]

Do this with motor drive big one which fit on the to of theaurdino

[@anandu383]

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 😉

[@helloworld9057]

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 .

Use two 9 v battery

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

[@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.
