Arduino 4WD RC Car | Joystick Shield + Arduino Uno + nRF24L01

[@nialnial7867]

The 2nd link in wiring diagram is not getting... Please help

[@ragunathanmurali7663]

The pin configuration in the wiring diagram differs from the code pls help!!

[@DannyHooster]

I made this project and it did not work. I do not know why. I copied the code for the joystick and the car does not work. I think I have a problem with the library. The transmitter and the emitter do not communicate. When I put the battery (12v) in the controllers of the L298N motors, one of the four motors starts to turn without order with the joystick. Please Someone can explain me what is wrong? thanks

[@xtero6003]

tube el mismo problema, sigo los pasos y no responde a ninguna funcion

[@Furkan-hd2rh]

Hello did you fix that problem i have the same issue. İf so , can you help

[@justaguy6100]

It's interesting rather than using steering servos you use friction to control steering. I realize servos raise the price of the car (more parts, more control points), but it works well and I applaud you.

[@zamharilbustamam8674]

hey sir can i get the libries nrf24l01

[@kierjexterbagunu7347]

hi. are you encountering a problem in their communication? for example, the motor will automatically start even if i am not pressing the button. thank you

[@veyselaksoy6558]

Did you use your car with number of 255 or less than that?Did you use PWM signal to decrease the power of your wheels' motor?

[@AndriyBaranov]

yes, you can find it in the code. For examle: #define ENA_m1 5 // Enable/speed motor Front Right #define ENB_m1 6 // Enable/speed motor Back Right #define ENA_m2 3 // Enable/speed motor Front Left #define ENB_m2 9 // Enable/speed motor Back Left / Convert the declining Y-axis readings for going backward from 470 to 0 into 0 to 255 value for the PWM signal for increasing the motor speed speedRight = map(yAxis, 470, 0, 0, 255); speedLeft = map(yAxis, 470, 0, 0, 255); analogWrite(ENA_m1, speedLeft); // Send PWM signal to motor A analogWrite(ENB_m1, speedLeft); analogWrite(ENA_m2, speedRight); // Send PWM signal to motor B analogWrite(ENB_m2, speedRight);

[@veyselaksoy6558]

Andriy Baranov but it seems me slow.You used 4 dc motor ,right?

[@AndriyBaranov]

yes. to increase the speed you need to use 12V for motors

[@AndriyBaranov]

I used 8V

[@capturecoder]

can u tell me why 2 motor driver is used i ha seen many video with one driver any reason

[@sanjitkumarpattanayak3647]

N4TECH yes I have the same question... anybody ....???

[@aliraad2114]

because every one has his one code

[@bamzzbambangsubagyo3046]

I try both of your code to my project, but the motors still cannot move. I read car receiver still show the zero value in the X & Y axis when I move the joystick. Could you help to to solve that? Thanks

[@rusithmadhuranga9903]

Hi,I want to made this car by using one L298N with H bridge motor connection.pleaze give me a code for it

[@AndriyBaranov]

Hi! Try this one: drive.google.com/file/d/1-dVjjjlY8RJxJ4kvSVeSQmEQXcQZE9c6/view?usp=sharing but I did not check it

[@Microsree28134]

Sir where the jumper wire used in arduino uno 1,you mentioned is that remove the jump wire from pin 0 and 1 from arduino ,i cant see any jumper wire in diagram

TEM COMO FAZER UM CARRO COM DUAS RODAS?

[@ukhindaffa1007]

All my connections are fine but still can not control it with a joystick. I do not understand if CODE is problematic or NRF. Still can not control through the joystick via NRF.motor right spin backwards when the code in uploud.

[@myonline88]

Sir please help me. I have built 3 Arduino robot cars and I have problems in all of those three. Here is my problem: for Forward and Backward command both motor runs normally, but for Left and Right command both motors run ridiculously slow. What could be the cause?

[@shashankverma2553]

why you doesn't use power bank in car, it will be more lasting then two cells.

[@ukhinrizqi6604]

sir i have followed your diagram. after i enter the code into arduino car.motor the right front of the rear rotate and hold even if the state stopped .. why yes sir.?

[@mishasoika6145]

Can Arduino Uno+Joystick shild+nrf24l01 be powered with 9 volt battery?

[@khaledbaraja1480]

Hi sir.. i think there are wrong on your code. For the example #define ENB_m1 is not 6. Is 10. 6 is for CE pin. Am already follow your step correctly but still not working good. My car not moving correctly even the light and horn not working. Can you please double check your code to get matching with your picture diagram. Thanks..

[@AndriyBaranov]

Ok.I`ll check it

[@AndriyBaranov]

Thanks, you were right. Try this one: drive.google.com/file/d/1SZCIFL2RSWMKdzMuzl8uoe9Mcfr8pkGu/view?usp=sharing

[@khaledbaraja1480]

Andriy Baranov thank you so much sir. I will try it tomorow.

[@khaledbaraja1480]

Andriy Baranov its working sir. 100% all works good. Thank you. But how if i use more voltage ( i use 3x 18650 3.7v battery) it save or no? Before that i use same like you just use 2x 18650 battery.

[@AndriyBaranov]

For this connections Max Voltage is 12V

[@nurbanarohim8073]

What components are used for the receiver

[@AndriyBaranov]

The same Arduino Uno R3 Board & NRF24L01+PA+LNA

[@muhammadhaziqmohdnoor6868]

Sir can i replace arduino uno with an arduino mega

[@TheGaavtiKalakar]

plz mention d Libraries for d rc car

[@idvfpv]

no libraries needed!

[@razoahmed8864]

My all connection are okay but still not able to control it by joystick. I didnt understand either CODE is problem or NRF . For double sure i bought 2 pairs NRF module. Still not able to control through joystick over NRF.

[@ukhindaffa1007]

right with me

[@Shootmaster1616]

How much voltage batteries we should use for car

[@AndriyBaranov]

I use Li-Ion 18650 x2

[@Shootmaster1616]

What codes we should write for remote please send

[@AndriyBaranov]

[@Shootmaster1616]

We can use Arduino Uno for remote please reply

[@ukhindaffa1007]

accidentally pin 0.1 do not I loose when uploading code is it problematic?

[@Shootmaster1616]

We want to copy the code for remote

[@AndriyBaranov]

Yes, of course, links are under the video

[@Shootmaster1616]

It's not opening

[@Shootmaster1616]

Send me the codes

[@Dr.Doom01]

there is problem in the code

[@Shootmaster1616]

We can use another modal nrf

[@AndriyBaranov]

yes

[@Shootmaster1616]

Nice but how to do the car collections please reply

Awsome video, If u have sometime I need your help please. I´m trying to adapt a hoverboard to my wheelchair to make an electric wheelchair because I can´t afford one. I´d like to know how to control the hoverboard with a joystick. Thank u very much!!!

[@gyanaranjanpanda9078]

you are best. nice car , sir how many meter its antenna range ???

[@AndriyBaranov]

up to 1 km

[@gyanaranjanpanda9078]

Andriy Baranov thank you, can I secure my connection between two nrf240L transreciver... how used code...

[@gyanaranjanpanda9078]

can I use one l298N motor driver instead two..

[@AndriyBaranov]

yes, but you have to change the code

[@gyanaranjanpanda9078]

Andriy Baranov I want use Nokia 5110 display module in joystick shield...can you tell how it's use and give me code..... please

[@РоманПугачев-я1п]

Ты один, кто сделал не рулевую машинку на Р/У

[@ВесёлыеРазноцветы2]

Круто вышло!!!

[@AndriyBaranov]

Спасибо!

[@ВесёлыеРазноцветы2]

Это я друг Лёвы)

[@TutocarloCV]

nice

[@xtero6003]

Señor saludos desde Argentina, probe el codigo y no me funciono, corregi los Enable como puso en : drive.google.com/file/d/1SZCIFL2RSWMKdzMuzl8uoe9Mcfr8pkGu/view?usp=sharing en el link y no tube resultados , probando el Joystick con el monitor serial , me indica que funciona bien el programa de EMISIÓN, asi que lo mas probable es que el error se encuentre en la parte de Recepción.

[@xtero6003]

PD: utilizo Arduino R1 para Joystick y Otro NANO para la recepción, Puede ser ese el problema?
