This is the second video of my "Arduino Projects" video series. It clearly explains to you how to make a mobile controlled Arduino 4WD robot car.
Here I used 'Arduino mega' for my project and if you want to work with another type of board you may have to re-edit a little bit the given code. For Bluetooth communication, I have used an HC-06 Bluetooth module. Every connection of the circuit configuration is clearly mentioned in the video.

Ayye mega eka වෙනුවට Uno eka ganna බැරිද ?????????????
Short and to the point, I wish every Arduino tutorial video could be like this one.
Thank you so much. If you have any doubt regarding any of my videos, join my fb group "Tronic Yaka - HELP DESK" and ask your question.
Thanks a lot for this great project. After some problem solving, of which i learned a lot, it works perfectly. In the app the buttons nr 5 and 6 where both placed as 4. This was confusing at first. Car could not stop because knob 5 did not exist but handled himself as being knob 4. After i corrected the knob functions in the app it now works perfectly.
Thanks, I was looking for that because I can't stop de car Lol
it works perfectly, thank you so much!!
Correct me if I'm wrong, but are you using a 7.4 V battery to power the 6V DC motors? That will reduce the lifespan of your motors
Thanks bro..worked perfect. Made some additional changes after the original code worked. Cheers!
My pleasure, bro. Cheers!
Bro please share with me also. That new code..
Hey. Is it necessary to press stop botton after each operation...
Cant we just make it work without using stop botton...
Thanks sir this was the easiest bluetooth car I have tried so thank u very much.
If I use Aurdino Uno it will be the same code that you described ?
Thank you for this video man! Btw I need help on trying to control servo motors using the L1 and R1 buttons on my wireless ps2 remote, I'm trying to control 6 servo motors for my robotic arm but I can't control them all because I can only control 4 total servos with the joysticks, I'm not really familiar with Arduino code so could you plz help me with a little code regarding on controlling a servo motor with the L1 and R1 buttons, this is for a project at school.
I am new to using the Arduino Nano and electronics in general. Can I implement a switch on an Arduino nano circuit that shuts down the Arduino nano so that it can be plugged in and out safely? Or can the microcontroller be plugged in and out without ruining a program?
i have four 1.5v batteries does it work on the circuit? and is it okay if i bought the same battery like yours in the video but instead of 2 i use 4
I did everything perfectly with Arduino Nano . start off everything works , after a few controling everything not moving . bluetooth stilll connecting but 4WD not functioning at all.
Have to reload the code into Arduino Nano to work again. Pls advise
Did u made aurdino uno based gesture controlled car ?
sir i have question . can i use any arduino atmega 2560 ? or it should only on the video ?
sir can you help me my problem is the forward and backward didn't work . all my program is same as your program i dont know why by the way i used hc-05
On power up, the left side motors momentarily move? Otherwise works well.
Hi! i was just wondering when you first turn it on without any of the Arduino installed, should the buzzer module be making loud beeping noises?
There is no buzzer module installed in this project. What buzzer are you talking about?
Can we use HC - 05 instead of Hc-06 bluetooth module
This is very useful .Thank you very much!
Hey is it OK if I would connect aurdino bord with its data transfer wire for power supply??
Hi your car was great but I have a doubt I have the same battery as yours but mine is 3.7 v and 6000mah battery so should I use it please tell fast
This was very awesome,, great work..❤️
Thand buddy ❤️
Hola tronic oye tengo una duda funcionara si le pongo un modulo bluetooth HC-05 o nesesita hacerse una configuracion en el codigo porfa ayudame¡¡¡¡ ¡UN SUSCRIPTOR MAS!
Best Arduino bluetooth control car video,Its awesome bro ,I want u to know that (it cleared my doubts)
Thank you for the feedback 😍 Hope u'll stay connected for the upcoming videos as well ✌️
Excellent video very detailed. Thank you.❤
Thanks 🤘
I built everything as suggested by this video. My car turns round and round instead of going forward & reverse. What could be wrong. Can you please suggest.
You have to use high current batteries in this project. Otherwise, the motors will not move properly.
i am new to arduino, i got a arduino uno to learn programming which has been my childhood dream, if you would tell me the code for an *arduino uno* it would help a loot. also thanks, i subscribed and i love ur videos =D
Can you please exactly say me what board is this and the model it’s arduino mega of which version
Sir...
Can u sell this progect.
Please please sir..
I try many time but not successful...

Hi, thank you for the video, but i have an error when uploading the code is it because i am using 4x 1.5v battery ? or something with the connection ?
You should unplug the RX and TX pins when you upload the code. Connect those two wires to Arduino board after uploading the code.
(For fast responses, join our facebook group "Tronic Yaka - Help Desk" and clarify doubts)
In the app there are 6 knobs (A,B,C,D,E......) and there should be an F. But it is not there, it is a D again. Can i rename this button in any way and call it an F ? In this way i can think of an extra function under knob F. Best regards, Leo, The Netherlands.
is it really enough two 3.7 li ion battery supply on 4 motors and 5v arduino ? do u use other power to supply with the rc car?
yes, it was enough. Check here 7:14
While using 1.5 volts both Arduino and l298 board are lit and Bluetooth is not working...but when it is connected with the system all lights including Bluetooth are glowing..
Is it due to battery voltage insufficiency
agar L298N ki jagah motor shield use kare to ? kya ye work kare ga ???
Congratulations great projects !!!
Edye souza Thank you for the feedback. Check Tronic Yaka up on Facebook and Instagram too.
Can I use two 9v batteries connected in series??
Great and easy. One issue - BT-## is not getting power, when using UNO. planning to use nano. will it work?
supplied power directly from L298N. solved that.
Well done aiya..i also want to try...and i think it will be easier thanks to your excellent explanation
Aneesha Perera yes, you can do this! Thanks for the feedback and stay tuned for more interesting videos!

then sir what version application of arduino should we upload
Good work brother...! Keep it up. Waiting for your new ideas
Thank you so much Aiad
Should i use two 9volt battery
bhai kya mai yahi connection arduino uno ke kar sakta hu aur karonga to kya iski coding bhi change karni padegi
Hello Friend !
Great job !
I rode this project and it worked perfectly, but I'd like to know how to stop the car. I have to disconnect the power directly from the battery.
Is it possible to disconnect directly from the app?
Yes. The fifth button is to turnoff all motors.
Hello there, your code is ok and it works fine as well as the connection to the bluetooth but my car is not moving. I have 9V battery. Can I use 2x 9V batteries to make this thing work? And yes when i remove the battery and connect it with PC USB it still does not move... Please help me. Tomorrow is my show. :/

I just understood the word Incredible. Thanks mate
Error compiling for board Arduino/Genuino Uno what should I do
can we use 9 V Hi-Watt battery and also can we give power to arduino first and then giving power to Motor drive...
If you are talking about the HW brand, then those 9V batteries won't enough current to drive the motors. So you have to use high current batteries as I have shown in the video.
You cannot first give the whole power to arduino board and then take power out from the arduino to power up the motor driver. This will destroy your arduino board. Either you have to give power separately or first give power to driver and then take wires out from it to power up the arduino.
hi charith sir i made the car N uploded the code as exactly as u said but when i give the command from the phone via bluetooth i doesn't do anything pls help me
Your channel's getting much interesting bro.. try path finder robot as well in your upcoming videos.. Keep being best... #suba..
Lasindu Hewawasam
Thanks for the feedback machan. Sure, I'll make path finder too. #ජය
If i use hc 05 module is there any problem ??
In this the program is correct? And we can put 9v battery instead of two 3.7v battery
lokesh ravichandran program is correct. The current output of normal 9V battery is not enough to run motors.
plz help me about this error.
after uploading code
my project will not work
"Sketch uses 2628 bytes (1%) of program storage space. Maximum is 253952 bytes.
Global variables use 189 bytes (2%) of dynamic memory, leaving 8003 bytes for local variables. Maximum is 8192 bytes."
I can't see HC05 on the discovered devices :( please send help
What changes should be made if we use Arduino uno???
I have used HW hight watt battery of 9 volt for 4 motor. But car not moving. I think it is the main issue of power supply. So, please suggest me which battery have to use.
I used "Ultrafire 4800mAh, 3.7V batteries.
(It's okay if you can find a battery which is greater than 1000mAh)
@@TronicYaka can we use 4 AA batteries for this?
Excellent explanation
hey gracias tu codigo me salvo nuevo seguidor
Can I use a uno board for your codes if I can't use please put the uno board codes
can we use 12 v two lead acid battery for four motor and one l298 driver module
Don't connect those two batteries in series. Cause the resultant voltage becomes 24V which has a risk to damage the board. So connect them in parallel.
The motors work with 7.4 v ?, Is not there a problem with that voltage?
No problem. just above 5V is enough. But those batteries should provide high current. Thats the main thing here.
Thank very much!
I have doubt shall we connect power supply to arduino uno from l293d? , as that you contacted as arduino mega
it worked even without the power supply connected to the motor driver
help me sir left and right motor are working but when all motor go forward or reverse did'nt work then the bluetooth disconnect to the app please reply me sir :(
im your top fan
Do I need to write same code if I use arduino uno
Will the same code work with Arduino Nano
superb bro.. 👌💪🏿
Thank you, Kasun!! Stay tuned, many interesting videos are coming soon!
Can I use 3 pieces or maybe 4 pieces of 18650 battery for this project?
Jikanime Time
Yes, you can.
Can I use another app? That doesn´t work on my android device
Hi bro I'm getting avrdude done but error is showing as problem uploading to board
Can I use different app to control the car?
Hm, Great job mate, But one question please, may i know why you connected the 5v to arduino 'Vin'? Is that necessary ?
Hachem Ben Amor we need to power up the motor driver as well as the Arduino board.
Motor driver powers up with the batteries from which I have connected there.
Then we take 5V out from motor driver and supply to our Arduino board.
(Join Tronic Yaka - HELP DESK" facebook group, ask your questions and clarify your doubts.
Tronic Yaka Tronic Yaka so ehm if I use a 9V battery is that okay V i mean will that do the work without any trouble ? And for how much time will the battery stay alive ? 5v for arduino and the rest for the motor driver. Thanks in advance.
Hachem Ben Amor
If you use one normal 9V battery, it won't work. Because it does not provide enough current.
You have to connect a high current battery.
Tronic Yaka Okay so what if I use 2x battery 9v. One is connected to motor driver and one connected to arduino.that will do I think right ?
Hachem Ben Amor
If you are giving power up the arduino board through "V-in"and "GND" terminals, one 9V battery might be enough for this project.
But for powering up the motor driver one 9V battery is not enough. At least you might have to connect more than six 9V batteries.
So it's better to buy some high-current batteries and connect them there. Those high current batteries are a little bit costlier than normal batteries.
Can i use arduino uno r3 not arduino mega
bro, plz clear my doubt . can we use servo motors instead of gear motors ..?? if so can u say each wire of the servo motor gets connected with the arduino board
No you can't. Servo motors are not suitable for this application since it gives just one revolution. If you need precise smooth motions, you may use steppper motors but they are kinda expensive.
@@TronicYaka but stepper motors can be extracted from old printers r8 ..!!
bro everything is done only my car is not running a last stage that is when bluetooth module is connected and i am pressing forward but it is not moving
Hola, que codigo poner para la velocidad de los motores?
please, I worked as a project for a car robot that works with voice commands, but after I installed the parts and connected the battery 12 volts, no light appears in the Bluetooth circuit and it does not appear on a mobile that it is present, but when you connect the Arduino to the laptop, the Bluetooth appears to work, if you allow help is necessary
This could be due to,
1. Wrong connection of battery terminals
2. Battery drained
With those battery how long it will last ?
does it work for two motors
mama L293d motor shield 1k aragen me car 1k hadanna puluwanda bluetooth pin fix karanne kohomada keyala denawada
I did everything correctly but after connecting to the mobile the Bluetooth module s red light doesnt come so the motor is not rotating . Can you please guide me ???
can we use this coding for 2 motor
well done sir..but when you want to use arduino uno board and motor shield will the connections still remain the same?
ozor obinna
Thanks for the feedback.
I haven't used motor shield and cannot give a proper answer now. I'll inform you whenever I get the information. Or you can ask your questions in "Tronic Yaka - Help Desk" Facebook group and get a quick answer.
ok thanks
Please give detailed explanation of batteries , how did you do it
Can I use l293d motor shield????
Motor driver of which brand do u have used in this video
Don't know the brand bro. Just ordered it online.
Hi my car is not moving, the motors work, I ve connected the data cable, I ve connected correctly and the bluetooth commands work but it does not move
do u have any arduino uno code for this project ?
When I powered up arduino board through laptop bluetooth module is blinking.But when connected to battery it is not .Why is that so?

how much batray for the driver motor?
Hi, pls answer me back ASAP as it's important. My Arduino Bluetooth name is ZS-040 but I followed everything in the video soooo carefully but when I turn Bluetooth on in my phone, there isn't any device to connect to Arduino Bluetooth. Is it HC-05 or is it different??
I used HC-06 in this project
@@TronicYaka ZS-040 is the same as yours too and should say HC-05 on my phone too. My expert arduino teacher told me so.
Btw though should the 5v of motor driver connect to arduino mega and also get a battery which holds around 12v and attach to 12v and GND of motor driver???? What battery do I need to attach to 12V and and of motor driver I have a battery box which holds 4.
@@TronicYaka what's the problem with ZS-040 Bluetooth and idk if it's HC-05 or HC-06. Btw I use 1 9V Battery and I connect it to one of the motor drivers and I connect a wire from the motor driver to another motor driver then GND it to Arduino Mega. Sometimes when I do testing from 5V to Motor driver pins to see if the wheels can spin, All 4 Wheels will move normally and spin normally and sometimes, the wheels wont spin or it will just move slightly and then stop.
How many Battery of 9V u need?? I'm doing a school project idk if I can buy more 9V Battery since I'm just a student. I no money.
Btw The Bluetooth doesn't show up on my phone to pair it so I can control robot but I'm not sure why it doesn't wanna show the HC05 OR 06. Is it bcs of power or......??? I'm gonna fail my school project as there isn't any program to it
Very much clear video thnks frm india
My pleasure ❤️🔥
Can I use 9v battery? If yes, what are the connections?
No you can't, Voltage is enough. But current comes from a 9V battery is not enough.
