Thanks
Hello bro!!!
In Online market Arduino uno's 2 varients available
1st is SMD & 2nd is Ic
So, which is best which one buy
Plzz help 👍🏻
Both are not a problem. The same thing can be done. Buy a cheaper arduino board
Hi sir can we use piezo buzzer (big) in this project and can i use the original arduino uno board but it doesn't have soo much GND plug in it

Connect to GND of motor drive.
Connect several wires to the same GND. It is not a problem. Do the same if the 5v pin is not the same
@@RobotLk thank you sir
Sir can i use arduino uno original board?
Hi sir can i use 9v hi-watt battery
Depois de pesquisar vários videos sobre robô controlado por Bluetooth e com faróis, finalmente encontrei este que ajudou a resolver meu problema, obrigado amigão!!
🙂Muito obrigado por assistir meus vídeos
Would it be okay to use non rechargeable battery in place of lithium ion battery?
Non-rechargeable battery can be used. But the battery drains quickly. Traveling speed may decrease
I wanted to add a few more features, so that requires the app to be reconfigured can i get the app link where I can reconfigure it?
play.google.com/store/apps/details?id=braulio.calle.bluetoothRCcontroller&hl=en
Hlo my whole thing working properly but driver module getting so heat up so tell me , what is the problem happening in the module?
Check if the wires to the motor are shorted
Sir, may I replace the 180 Ohm resistor with a 330 Ohm resistor?
No resistor required
The good project is very nice we have seen your robots I like it
Thank you very much
Hello brother. I just wanted to ask what can be the possible reason for motor not rotating when i try to give command to the motor driver using hco5 bluetooth module... your reply will be helpful. Thank you🙏
What is the voltage applied to it?
@@RobotLk 2 Li ion battery of 3.7 volts each.
Did the code upload correctly?
@@RobotLk yes
Is the motor drive connected by ENA, 5V and ENB, 5V micro jumper.It is shown in the circuit diagram.
In video I saw, that bluetooth module you are using is powered by 3-6V and has 3V logical level. So I want to ask if there is no need to use logical level converter or power supply downgrade? Is bluetooth module 5V tolerance? Thanks for answer.
5v works correctly, I am using hc-05 blutooth module.
It is not necessary to lower the power supply to the RTD pin
bro, I already like & subscribe your channel ... what changes should I do if I use the 293D driver?
These days there is a lot of work, I will make and send the code
@@RobotLk if you have time maybe you can make a video with the motor driver 293D. and of course the video that you make is very useful for many people .. thank you in advance for the kindness you give
Good day :) I just want to ask what is the possible cause of my problem. all components are working just fine but when I try to command the motor driver through the phone, the motors wont rotate at all. all components are working fine when i tested them and I also checked the connections and they are also ok. I suspect that problem is on the voltage flowing through the pins from the arduino to the L298n, but I am not really sure. pls if you can answer me that would be a great help :) Great video by the way :)
How much voltage was given?
@@RobotLk well, the h-bridge is providing almost five volts to power the Arduino. Then if I use the arduino to power the Bluetooth, the arduino only gives about 3.44v to the bluetooth which is clearly not enough. so i decided to directly plug the bluetooth module to the H-bridge's gnd and 5V output and the bluetooth works just fine. then as for the voltage from the arduino to the pins in1, in2.. it has 0.01V or no voltage at all to every pins regardless if i am connected to the bluetooth module or not. sorry for the long message, I was just making sure that I am explaining every detail :) thank you for responding :)
@@RobotLk and by the way I am using the green version of the H-bridge, I dont know it affects anything because I am fairly new to electronics.
Hello, I have the same problem, did you solve it? and if you did it, could you tell me how? thanksss
Only issue is code check ur code and find the pins configuration
my arduino bord is arduino mega do I have to choose the board as arduino mega
please reply
Yes, select arduino mega .You can use any arduino board for this
Broo can i get a fast reply if i connect battery to 12v of motor driver there is no red light glowing
Id i connect to gnd and 5v it is glowing is the motor driver problem..????
What is the voltage supplied?
9v
we want to put two batters for arduino and to L289N plz give reply
It is enough to put two batteries
Excellent project brother. I appreciate it.
I have 3 questions. Please help me.
1) Can I use arduino nano?
2) If I use arduino nano, what will be change in diagram?
3) If I use arduino nano, what will be the change in coding?
Arduino nano can be used. The circuit diagram is no different. The code doesn't change either. But while uploading the code, select arduino nano as the board
@@RobotLk Will everything work properly? Will the motors and lights work as same as here?
My brother, when I press a button, a long press, it walks and never stops. Please reply because, unfortunately, it is a graduation project
Same problem
I have the same problem did you find a solution ?
Yess bro for me also same
@@c.tcreations12 try to use other app which has stop button
Use another app and set commands as your code says and add an Stop option there
Hello sir is the DC jack male and female is mandatory to use in this model
Not necessarily. Apply a switch

Best one , helped me 👍
Glad it helped
sir may I use two battery in stead of 3? will it work?
Two batteries are not a problem. Enough to operate properly
sir i dont need light and buzzer what should i do
with coding
No need to change the code . Do not connect light and buzzer.
Hi sir i did everything thing you did also same Coding but when i give commands my motor doesn't respond
Could be a problem with the bluetooth module or the power supply
Sir which app did you use to make the diagram can you pls tell

@@RobotLk I used flipcart power bank and its output is of 5V
Is it a natural thing when the cellphone is pressed (control) and the car's movement is slow? is this normal? Please respon
The signal given by the app is received late by the arduino car
Otherwise the power provided is not enough
@@RobotLk what the solution to this problem?
why my bluetooth isnt turning on, i follow you the exact thing you do, please help me
Hello bro!!!!
I made truck and I control that truck from my phone
I have already purchased all components.
So, that truck I have made has 2 motors
1st for rear wheels & 2nd for left right (steering)
So,the main problem is I don't have code
So can you please help me to get the code or sketch.
I hope you understand my problem

SUPERB TEACHING but i have a
small doubt can u send me the programming codes of this car which u made
Izin bertanya bro saya memakai arduino uno tetapi saya hanya menggunakan 2 baterai 18650 tapi arduino tidak menyala
i can't see the code on the website link that you provided in a description
Thanks for informing. I updated the link. Now the post will be shown
Thanks a lot sir 😊
i connected everything as shown in video, but bluetooth is not showing on my phone, i tried other phone but still its on showing..what should i do sir..?
Does the bluetooth module LED blink?
what is the library you use in L298N?
The l298n motor driver does not require a library. It's just a motor speed controller

Bro my l298n motor driver getting heated after runing the car for more the. 2 to 3 minutes i am using 2 lithum battery of 18650 and 3 also but the problem is same
Check if the wires to the motor are shorted
Hey buddy may i use power band instead of batteries?
The voltage in the power bank is insufficient,Maybe it works because the amperage is higher
Hi, Many thanks for your tutorial. Unfortunately I have a problem. All wiring is correct, code uploads OK, HC-05 is paired with mobile phone and Bluetooth car control dashboard is on . I am using a Uno R3. When attempting to connect to car, the HC-05 appears as paired but the car control does not connect. The two LEDs, red and blue, on the HC-05 are continually flashing. Jim
Any suggestions? Jim.
Is the hc-05 Bluetooth module not properly connected to the mobile phone?
While uploading code in Arduino don't connect your hc 05 module in Rx and TX pin you need to unplug it... Connect it after you flash your code in arduino
Hola amigo muchas gracias me sirvió mucho.
Como conecto los Leds para la estacionaria y en en que pines van en el arduino.

Hello brother
A question, you are using (Battery 1200mah 3.7V 18650 Li-Ion Rechargeable) right?
three of those would give a total of (3600mAh - 11.1 V )
I just wanted to ask if that is how your circuit is working
Can you confirm if everything is correct? please
And one more question: doesn't yhe circuit overheat or something ?
"What battery do you recommend I use? voltage and amperage please"
*I am using arduino mega 2560*
Use 18650 li-ion battery or 3S li-po battery.Through the motor drive, 5v is given to the Arduino.Motors only get 12v when they reach maximum speed.It doesn't go through arduino so there is no problem.
Bro he connected it in series so the battery voltage gets increased to 3.7*3... The battery capacity increases only when it's connected in parallel
I can use normal motors us.?
Yes you can
Hi sir in the battery 18560 how much mah sir please say sir
Use batteries greater than 1000mAh. 1000mAh or so
Thank u sir😊
You are welcome

Your code helped me building the project though I am able to drive the car but speed is very slow compared to yours shown in the video, can you please share the detail about the speed input you gave in the code to gain good speed. Also I had to make the changes in the F\forward/backward/righ/left codes as it was not align with the direction of the car movement. Finally it is running. But please share your input to increase the speed. I am using 4x1000 mah 1.5 v battery for L298N driver module and 12v Lipo for Arduino UNO R3.
Use the 12V lipo for the l298n motor drive. If it is made according to my circuit diagram, there is no need to supply power to the arduino. Depending on the voltage applied to the motor driver, the speed of the vehicle will increase.
@@RobotLk thanks for the help. I'll try with 12 v lipo. But I am using breadboard instead of direct connection of L298N and Arduino. I'll also try the direct connection.
