Hi! This feels surreal. I remember watching your videos and how you helped us with our project-a hand sanitizer dispenser-back when I was in high school. Now, I'm watching your videos again as a college student! Thank you so much.
Hi. Can you share what RPM motor you are using. I am using 100 rpm geared motors and it takes about 3 cms to stop and that is causing the sensor to cross the black line.
Hi, your video is amazing, can you tell me How long should the chassis of the car be? Please. I need the measurements of almost everything that should be used . Thank you and I really hope you can help me 😢
Amazing video dear and good explanation. I followed each and every step as you explained and also used rechargeable battery motors are not working sensors are ok. Please guide
Sir, which analog pin of the positive and negative pin of the 5v buzzer. Sir, can I have to write the code of the 5v buzzer in the line follower, will the line follower robot work or not? Sir, I put the buzzer pins and the led in the Arduino Uno, but the Arduino line follower robot s buzzer and led are not working when I turn on the line follower, the line follower robot works but the 5v buzzer and led are not working. Give me the circuit diagram of the Arduino line follower robot s buzzer and led visual indication.
Please check the buzzer specification for pins . Also first check only buzzer working with Arduino and then integrate with line follower code . Go step by step , have patience 😜 and it will work 👍🏻
hello there, thanks for you video you are already carring us through our university projekt. But in our project we need to go the track backwards. Do you belive its better going backwards or let the linefollow robot turn 180 degrees at the end of the track and then drive back. In our track the end of the line is build with a big black point. So that both sensors see black and stop. We would really appreciate an answer. Greetings from Germany
I would suggest make a 180 turn . Right now this robot stops after seeing black big spot . Rather than stopping it , let it turn 180 degrees . You need to adjust delay for this 180 degree rotation . I don’t have robot assembled to test it . So you need to do it on your robot and see if it works . 👍🏻
It’s quite simple . Just join one end of multiple wires together and then attach single wire to this joint . I used this so that I can provide 5v and gnd to all components from l298n drive .

Thanks for visiting the channel 👍🏻. It looks like the problem is not with code . It is surely the problem with the hardware . Do you have other Arduino uno board ? If yes try uploading code into new board . And see if it works . I am assuming you are not using Arduino nano .
I think you can do it easily . Just try to find out how to use L293D driver . And update the code accordingly. Give it a try . However I am not sure why you need to use L293D where as L298N is simple to use .
Thank you so much for the video it was really good, I'm doing the same project but I'm adding a PID controller to smooth the movement so could you please help me by guiding me what to add to the code. Thanks in advance bro
Thank you very much and I wish all the best for your project . Adding PID to such robot is quite challenging. You will need to use multiple sensors and then tune PID . I would suggest you to check some other videos where they used PID . Good luck 👍🏻
Thanks for you're great video! We're doing a quite similar arduino project and we were wondering if it's possible to let the robot make a 180 degree turn, so that it can make it through the parkour in both directions.
You can make a code change to rotate robot . Adding proper delay will rotate the robot through certain degree . Not exactly but roughly . Give it a try 👍🏻

Hey I was following your video to make a Line Following Robot of my own, and I have everything set up as you do in the video, but the light on both of the IR Sensors labeled POWER is constantly lit red, not green like they are in your video. Also, the robot itself is not driving (the motors aren't spinning whatsoever). I was just wondering if you knew why this was the case and if you knew a fix for this issue. Thanks!
Thanks for checking out the video 👍🏻. May be your IR sensor power LED is red . You should calibrate the sensors by placing them on black and white surface and adjusting the knob on sensors . Check the video properly . Also make sure you provide only rechargeable battery power .
@@hashincludeelectronics Yes my Power LED on the IR Sensor is red, I was wondering if you knew why. I'll have code that I used to test if the robot could even drive attached below, and I believe something may be wrong with that as well so if you see anything wrong with it let me know. I calibrated the sensors just as you did in the video, so I do not believe that is an issue. The robot is detecting a change when I move it over the black tape, so again i do not believe that to be the issue. I checked the rest of the video twice, and everything seemed correct according to the video. And the battery I am using is a 6v battery pack, but I tried to power the robot by using a 9v battery and by plugging it into my laptop and running the code, but neither of those work.

would this work on more complex map with inersections, curves and straight lines?
@@Zohathezombie23 no it will not . It’s very basic robot 👍🏻👏🏻
bro you are telling the most randomest shit i have every heard so idk how u got 2 extra wires to connect with the IR sensers so i cant undershand shi so pls help me i need to make this for my science project pls help me here
Please check the circuit diagram and video and try to make connections. Don’t worry you will get it sorted 👍🏻👏🏻. As I said it’s a one to many connections of wires . It’s like providing 5v and gnd to both IR sensors using wires .
sir I have connected all the connections like you said in the video . the car is not working please help
Thanks for checking out video 👍🏻. What issues are you facing ? Could you please increase the speed in code MOTOR_SPEED till 255 ? Let me know how it goes .

Can we make it without using adruina
Yes you can. Just provide output from sensors directly to L298N motor driver module . But you will have to do some testing and analysis . 👍🏻👏🏻
Its showing " rightMotorPin 1 was not declared in this scope"!!!! What might be the problem???
Plss answer by tmm
Copy past the code properly 👏🏻👍🏻
cant find the code plz help me
Code and diagram link is provided in the description of the video 👍🏻👏🏻
Is it necessary to import the file every time before using it?
No . You just need to upload code once 👍🏻👏🏻
Bro can we connect Bluetooth chip in this
Unfortunately we can not . 👍🏻👏🏻
Can we use cheaper one Arduino
@@advocatejyostnajadavdinesh8724 yes we can 👍🏻👏🏻
Where to connect the switch and battery? Because it differs from the circuit diagram you gave in description
The circuit diagram is correct . Please follow it and also video step 👍🏻👏🏻
All connections are correct but the car is not follow line and the motor driver is not run please explain tomorrow I will submit my project 13/7/2023
Please use rechargeable battery to avoid any issue 👍🏻👏🏻
I use the rechargeable battery but it not work so 2days time I will submit my project
Can you do it faster more than ?
Not possible in this robot 👍🏻👏🏻
how to make ir sensors by itself ?
Sorry but I did not understand your question 👍🏻👏🏻
