I heartily thank you , nor just because of your work but the main thing is your code , your code absolutely works great, I have watched lots of video but none of them submitted a crt library in the code file for bluetooth I don't know what reason they would have , but I heartily needs to congrats you , for my resume I am doing projects and learning several things while I have also spent my pocket money to it , at first wrong code makes me feel discomfort and I even thought waste of money why should I, your work motivated me to do so and learnt lot of things , thank you so much from bottom of the heart😊

"Motor Protector" Library?? Sorry I didn't understand. No, you can't use 3 AA batteries because they are not able to provide enough power to drive 4 motors.

It depends upon your bluetooth module breakout board.

No issues. You can use cable with any colour.

[@aayushbhatta9668]

What is the difference between soldering the points in 0 and 1 and fitting it directly in the pin?

No difference in the working of the RC Car. Only difference in connecting the pins directly is that it will make the connection process much easier.

The Arduino board is taking power through the motor driver shield and in the motor shield you can give voltage between 6 to 12 volts. 9 volt is the sweet spot.

it say Compilation error: AFMotor.h: No such file or directory what do i do pls

[@UtGoTech]

Install the Adafruit Motor Shield V1 Library through Library Manager then upload the code.

[@yosefb5066]

Great job! Please is there a difference between bluetooth module (hc 05) and (hc 06)?

[@UtGoTech]

Yes, HC06 can operate only in slave mode.

[@oishyislam1341]

The code is showing error its showing 'MOTOR12_1KHZ" was not declared in this page!!!! How to solve this problem?

[@UtGoTech]

Install the library properly.

[@ashishkumarsingh6285]

I have done everything but my bluethooth is not showing in available devices to connect i also tried changing bluethooth but the problem is same what can be the problem? I have used L293D motor sheild for my project. Light is coming in audino and motor sheild. But bluethooth light is not blinking for both the modules. Please guide

[@UtGoTech]

Directly connect your Bluetooth module to 5v and ground of Arduino board and if it is working or not

[@zeynebelmousa7912]

i have a HC-06 Bluetooth module , I can pair up and connect but after an unspecified amount of time, 2 minutes Or when you give the car a command to move when the Bluetooth connection is cut off

[@UtGoTech]

One of the reason for this is voltage drop. Properly and tightly connect cables and use lithium batteries

[@Saffier.b]

mines only works when i put the moderboar(adruino) in my pc how can i make it so my bateries charge the moderboard and the driver module

[@UtGoTech]

Connect batteries to motor shield and also connect the jumper as shown in the video.

[@Saffier.b]

@@UtGoTech do you also know a 18650x3 battery holder with on off switch or a 18650x4

[@UtGoTech]

18650x4 battery holder is available in market

[@josemaribautista7786]

Hello sir , i have a question, why does my hc-05 suddenly dont work again, i have been using it for few days then suddenly it won't work again , it is blinking but when i connect it to my phone it cant function.? What is the reason for this and what can i do to fix it?

[@UtGoTech]

Are you able to connect to your Bluetooth module?

[@VishnuShevanphto]

Yes it is connected

[@UtGoTech]

Does Bluetooth connection get disconnected after giving command?

[@UtGoTech]

@VishnuShevanphto check if it disconnects after giving command

[@HURTADO-pnund-]

Hello, excuse me, please can you tell me the name of the application

[@HURTADO-pnund-]

I have another question, can you use a 9 volt battery or is it necessary to use lithium bacteria?

[@UtGoTech]

9volt will not work. You have to use Lithium-ion battery.

[@UtGoTech]

After you raised issue I found that the App is temporary disabled or removed form the play store. You can use different Bluetooth RC Controller App from play store but you have to map the codes according to app. If you still want to use the same app then please Contact me through Instagram or Telegram, I will send you the app.

[@HURTADO-pnund-]

ok and can you please upload a video or tell me how to assign the codes of an application to the arduino program

[@iikongo3271]

excuseme iwant the arduino code?

[@Parul_mehandi_design]

Sir can I use simple dc motor in place of gear motor

[@UtGoTech]

You can use simple DC motors.

[@princemaverickscaisip6898]

Hello, can I use hc-06 module instead of the hc-05?

[@UtGoTech]

Yes you can use it.

[@shveta7777]

Sir can you share the link from where we could buy ardiuno uno

[@UtGoTech]

You can but it from Amazon or Flipkart

[@UtGoTech]

Or from local shop

[@siddharthkoppu6901]

Hi i have a problem when i am connecting the Bluetooth module to motor driver it Bluetooth module doesn't turn on whereas when i connect the motor driver to my laptop through Arduino board it turns on. Please tell me the solution because i have a project this 29 and it is not working

[@UtGoTech]

Have you checked the jumper on the Motor Shield

[@malathikoppu7415]

Yes but the same

[@malathikoppu7415]

Can it even support 15 volts of power using 4 lithum battery

[@UtGoTech]

No. Use only 2 lithium ion batteries

[@anthonydorothycagampang3431]

Sir I have a question, I have followed all your steps but when I turn on the DC Batt the BT Module wont on.

[@UtGoTech]

Check if your Bluetooth module is faulty or not.

[@aashanaphade4305]

Hi i had one query? Can I use 4 1.5v cells?? Please reply fasr

[@UtGoTech]

No, it will not work.

[@shveta7777]

Hello Sir Can you tell me that what would be the code if I would use 3 rechargeable battery of 2600mah instead of two battery and would the project work

[@shveta7777]

To make the car move more faster

[@UtGoTech]

3 x 18650 Lithium ion batteries will be too much for this project. I suggest you use only 2 such batteries.

[@UtGoTech]

Use high RPM BO Motors for faster speed.

[@gojoplaystion]

When we finish coding do we need to connect to the car and take it out 😊

[@UtGoTech]

After uploading, disconnect the USB cable from Arduino Uno Board

[@KhushiKumari-w3i2o]

Sir ab konsa app use kr skte h y available nhi h to

[@UtGoTech]

You can use the backup app or look for similar app in Play Store

[@Chartered_Edu]

Can I make this with oly 2 wheels ????!!!! Pls reply 🥺🙏🥺

[@UtGoTech]

Yes.

[@Chartered_Edu]

@@UtGoTech then wat will be the connections ??? Pls tell me 🙏🙏🙏🙏

[@UtGoTech]

Connect first motor in M1 terminal and second motor to M2 terminal of the motor shield.

[@Chartered_Edu]

@@UtGoTech thanks for the reply brother 🙂

[@Virtual-Classmate]

Bro plz give the circuit diagram

First install Adafruit Motor Shield V1 Library through Library Manager. After that upload the code.

[@Rifatullah_Ahmad_Zubaer]

can you give me a link. i am a bigenar@@UtGoTech
