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)

the robot does not move forward on the line… when i lift it in the air the wheels start spinning… as soon as I put it down on the line it does not move forward

[@ashrafabiaz2552]

Bri, I am having the exact same problem.

[@ashrafabiaz2552]

Did you manage to find a solution for it. If so, please let me know. I need it urgently.

[@MakeDIY9]

Guys calibrate the robot first.... Watch my video carefully...

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

[@herambkadam8693]

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

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

Sir your videos should be long so we can understand better

[@shortcraft2089]

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

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

[@itssouravvv]

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

[@siddharthasingh9570]

The obstacle avoiding robot should be made with arduino and there shouldn't be any beeping sound in it. I just request you to plz make a video on it .

[@MakeDIY9]

Ok bro ☺️

[@anonymous15042]

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

[@maskb2k876]

Can we do the same with aurdino nano

[@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 .

[@TheStromer]

Use two 9 v battery

[@menukabandara3374]

you are perfect man👌

[@deenadhayalan8183]

We compalsery have to use only Arduino Uno R3

[@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

[@mralap6529]

Bro you thought about that!! ? I requested you to make Arduino car controlled by blutooth gamepad.🙄

[@MakeDIY9]

Yes i have thought about that at next i will make a rc car with joystick switch. Can you sens the gamepad link? I need to see it first.

[@mralap6529]

@@MakeDIY9 my gamepad isn't available now on Amazon but my gamepad one of type and supports 2.4ghz like wireless mouse. Ok I've found my gamepad www.amazon.in/dp/B07Y8B3LCB/ref=cm_sw_r_cp_apa_i_NlfyFb8DB48WJ you can see the discrimination in amazon and it also supports 2.4gzh they didn't mentioned.

How to control each motor individualy?

[@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

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.
