thank you so much man!, mine worked so well! :D
You're welcome!
ج
Me too
Mine didn't worked XD :(
Man for programming what did you do for Sonar(trig_pin...)?
Thank you, sir, my obstacle avoiding robot work. Thank you for giving me the code, circuit diagram and the newping library. Thank you,sir,🙂🙂🙂🙂
How many hours it tooked for the project?
You are awesome...
Step by step... very nice..
No chance to beat u.
I saw somany videos, but this is very clear explanation.
Thanks for your hard working efforts.
Thank you so much 🙂
Thanks bro tommorow is my science exhibition tq
Superbe explication du montage et du code.
Félicitation.
I have personally built one following your video and its totally fine.
Thank you youtube....finally something good reccomend...this is perfect....thanks
Thanks
Thank you dude! goes well and having fun tweeky it.
great job! i really love this project! if i want to make a random rotation, wich delay i have to change?
Hello , i'm testing the code, however when i added the readPing function and recalled it again back above, it is showing me that the function is not declared in this scope , what could the problem be ?
Add the newping library
Thank you for that amazing video
It is warking 👍👍👍thanks for the code😊❤❤
How much amps do i need out of my 6v battery to make this work? and what is the maximum voltage that I can use?
3A is sufficient. Can be used up to 12v
Nice work, thank you very much for sharing. Why not use the speed function offered by the L298 bridge to reduce the speed of the robot? my greetings
I used it for a blutooth car
Thanks for the advice.👍
@@RobotLk thanks for your reply, when you try with the robot avoiding the obstacles please give me a sign, probably it will not work.
What happens is that only the sensor and the servo motor work
yes that's it, moreover if it was a 2-wheeled car for example, there will be only one which will turn, with annoying parasites which will be generated by the Arduino board
It doesn't require any code for its operation right??
Thankyou so much for the code
Can someone please tell me how can I edit the code provided so that I can make the robot turn wider after it stops in front of an object?
12:09 Increase the distance value shown at the location
@@RobotLk alright thank you very much!
I using this robot in my course. We are having trouble getting the motors to react, they don't rotate. The servo reacts correctly when we pass our hand in front of the ultrasonic but the motors do not rotate. We have triple checked the circuit and are fairly confident that is correct. Have measured the battery and we have 8.4 V at full charge.
Are the ENA, 5V and ENB of the motor driver connected by a 5V microjumper?
@@RobotLk the ena and the enb not conected ...i connect the en1 1n2 en3 en4 to the arduino
and connect vin arduino to the +12v
je relier maintnant au 5v aussi mais seullement le roud reight ce travail
merci je trouve le defaut dans l'ampirage
Same condition occurred
Well done it,s superb
Thanks
thank you so much. mine worked really well.
You're welcome!
Good job bro... well done. ..
Thanks bro
Thank you for the video.
I have two questions.
1st one is can we use a 9v battery.
2nd one is do we need to take 2 9v battery.
9v battery is not successful.Use two 18650 3.7 v batteries

Help mine does not work reverse all four wheel my reverse only is working right side working ihave l298n but when forward all wheels are working
It has very speed nice
hii im facing a problem the car is not turning towards left except that its functioning ,
any sugestions plz
Bro i did same as the link you gave and watched the video 8 times and made same project. sensors are working but motors are not working please help me
Sir I have use 9v battery instead of 18650 battery
Thnx for the assemble video! I have a few problems. The car gets power by connecting it to my pc. Once it is connected, the servo moves once if i manually changed the position beforehand. Then the car starts driving straight and does not stop. The servo and sensor do nothing. Any ideas?
There may be a problem with the ultrasonic sensor module.Check the wire going to that module again.
Hey, in many videos I saw people using a Sensor Shield V5 on the Arduino, but you didn't. Does that mean I don't need it? Thanks for any answer
The sensor shield is easy to use, but only the l298n motor drive, servo motor, and ultrasonic sensor are used here.Applying a sensor shield costs a lot of money. I didn't use it because it could be used for something else.
hi
i make it but robot 🤖 🤖 rotate right and servo motor only check right
Hello i have done everything as per the video but my motors are not moving ?

Happy to help
Sir i do all the step but i have little problem he don't move forward everything work so will
Bro are the schematics correct or the video bcz both of them r diff the scheme in vid is diff than in Google drive
It doesn't matter, it works both ways, connect it as per the circuit diagram .It's more convenient.
Hi! Thank you so much for the code. The car runs well, but when I tried to add a IR receiver or a sound sensor, it kept giving me "readPing was not declare in this scope". I made sure I have a newping libary installed. Do you have a phone number I can each you out? Thank you for the help!
Excelente.
Hello, Can I use the same logic of car to design an robot who detects crack on railway track? If IR sensor senses obstacle then crack is not there and if Sensor does not finds obstacle then crack is there. Will it work, what modifications I need to do in code and circuit as well??
You have to use pixy cam or esp32 camera to make it from open cv. It is very complicated
@@RobotLk Thank you for your inputs, Can this be done without using camera ?. Can we use infrared sensor to detect crack on surface of railway track?
Which version of arduino uno did you use and does it matter which version of arduino uno I use
Arduino uno, mega, nano, Lilypad, nodemcu can be used on any board
Hihihihihihi we love that review , bla bla production
any method to use this same configuration of obstacle avoidance and also have it be controlled by Bluetooth?
I will explain how to build an all in one arduino car in a future video
@@RobotLk if possible also add a depth avoidance sensor input as well using a IR sensor so it doesn't fall off of the edges
Eka ptta bro😍
Thanks bro
It's super😎
Good example...Sir ...tnx for this video....

Sir which rpm gear motor do u use sir and which mah of battery do u use sir
Two Li-ion 18650 batteries and four tt gear motors
@@RobotLk no sir iam asking how much rpm is ur motor and what is the mah of ur 18650 battery I hope u will give a solution
In Arduino do you have to Wright everything or does it already have everything to make it work
I do not understand the question
@@RobotLk when you go to program the car do you have to wright the script
Make it as per the circuit diagram. It is more accurate
Thank you ayye
Any time malli
Bro... My motors are not running for some reason. If i connect the Arduino to laptop than it works. Is it power issue. How much power does it need to work properly??
7-10 Voltage and 1000mAh
@@RobotLk I use 9v 2.3 amp battery. It didn't work though

Thank you very much sir.Sir,Can i Power Supply arduino and L293D motor Shild at Same Time?
Yes
@@RobotLk Sir,How sir ?Before powering the l293d motor shild ,i remove any things is motor Shild?(yellow colour part (near the power supply pins)?
I just did not understand
I use the l298n motor drive for this

Hi you project is good.can I use two 18650 battery and arduino Uno board for this project.
Yes .Two 18650 li ion batteries are required
I have an error that "readPing was not declare in this scope" while compiling sketch. How can I fix it? Please reply
Did you add the newping library?
Sir instead of 7.4v battery can I use 2) 3.4v battery
Or recommend any other battery 🔋
I also used two 3.7V batteries. Use a 3.7 V batteries
Thank you sir
I did everything but the car doesn't move when I plug the cord. The lights come on but nothing else happenes. Pls help

great job
Can I use a 9V alkaline battery as the power source for this project ?
The 9V battery cannot be used because it does not have enough amperage
sir how to find its transfer function?
Sir what is the green and orenge lights.its normol
yes
How does the code stay on the car? My car only moves if I keep it plugged in to the computer after uploading.
This is because the power you provide is not enough.
When connected to a computer, the Arduino board, servo motor, and ultrasonic sensor all operate at 5v from the computer.
Insert two 3.7 V batteries
Ok
@@RobotLk I will try that
How did you connect bith servo motor and the sensor to Arduino 5V ? There is only one 5V pin in arduino.
Connect two jumper wires together
Or connect it to the 5v out of the motor drive

bro we can also use 2 wheels instead of 4 and a caster whee with the same code?
Yes you can.
The code does not change
@@RobotLk ok thanks for replying bro
@@RobotLk can i get your insta id or something else..so i can ask any query actually i am new to robotics
♥️♥️please please replay ❤️❤️
Bro when I done this project servo motor and ultrasonic sensor were rotating properly.
But now only wheels are rotating and servo motor is not working
Also I checked each and every component all components are working separetely.
Also all connections are ok.
❤️❤️Bro please reply what submit This in college♥️♥️
Voltage and amperage are not enough. Use two 18650 LI.Ion rechargeable batteries for this. 9 V batteries and AA batteries do not work properly.
I cannot understand why the car can turn around? What is the principle? The 4 TT Gear Motor wasn't only allowed forward or backward?
When there is no obstacle in front, the car does not move forward
successful but some issues with ultrasonic sensor not detecting sometime

Hello will 4xaa battery enough?
4 AA batteries are not enough
Hello I made this as it you have said it's just I used a 4 cells battery pack and connected it accordingly to LM298 drive module as shown in circuit diagram. I also connected one 6V battery in Driver module using 5V supply and grnd supply. The car is operating at a very low speed and the sensor is not rotating I am not able to find a solution I have tried it ample of times
The voltage and amperage of 4 AA batteries are insufficient.use two 18650 li ion batteries. 9v battery also cannot be used
@RobotLk ok I will try that out and let you know If I faced the problem again
6v battery should be connected to 12v in and gnd
Not 5v and gnd
It really works thank you , but I have a question how can I contact you ?

Bro i used HY-SRF05 sensor and connected with arduino for checking, it shows 0cm detection or no pulse from sensor. what can i do ?
Check that the terminals of the ultrasonic sensor are properly connected.
A newping library is also required for the ultrasonic sensor to work
@@RobotLk terminal means what bro.. Iam MCA student

Hello, I have a problem when the car moving forward the right side DC motor move slow & sometimes not moving I need to move the tyre using hand then it worked but still slow but when reverse it worked. Can you help me? Thanks
Did you edit the code?
@@RobotLk no, i just copy&paste the code. maybe my motor broken?
If it works in reverse, there is no problem with the motor,Check the connection of the motor drive
Even after the installation of NewPing library I'm getting a compilation error. Can someone explain why
Have you uploaded the code to arduino before? What is the error? Maybe ch340 usb driver is missing
Hello can i use 3 3.4 V batteries instead of 2?
3* can be used. But the speed will increase a lot

Can i run the car with 6V battery or will i need to have 7 to run the motors
6v is possible .9v is good
6v is sometimes possible.
What is the amperage of a 6v battery?
I upload the same code but its not moving ;sometimes the wheel moves but not all but servo motor is working
Voltage is a problem. Use two 18650 li ion batteries
After adding new ping file we will also have to add other files like servo motor and ultrasonic sensor ?????
Only newping needs to be added
@@RobotLk bro and i have Ardino uno so i select in port ardino uno and com 3 na
ok, select the last port
@@RobotLk and coding is same na bro
There is a change in the connection of the motor drive. That shouldn't be a problem
Can i use L293D motor driver shield to this
Plz reply
You can also use that motor drive. Then the code and circuit diagram will change. In addition to the newping library you will have to use another library.
You can get code,circuit diagram and library related to L293D Drive from this Link......drive.google.com/drive/folders/1CR13RmaBUM0LZ6JkvYnq06Au3obji-NK?usp=sharing
