Check description

Choose High RPM BO motors and use fully charged batteries.

You will get in example sketches

@@UtGoTech okay thank you

👍

What can I do

I have install adafruit v1 library also

Share error code

Have you selected the correct board and port.

Sir port slected

Check if the sensor is faulty or not.

@@UtGoTech but the sensor is a new one

@Seynuja check using an ultrasonic sensor code if it is working or not.

@@UtGoTech ok

@@UtGoTech how chek it

Glad you enjoyed it👍

Yes.

Yes, sure🤖 drive.google.com/drive/folders/1B1gTeydaGb0U7vTGabXF_w1qiffc97PI?usp=sharing You can also get it from video description.

Ok. I will make and upload as soon as possible.

I think you are asking the wrong question. You can use Arduino Uno instead of ESP8266 and use the L293D motor driver shield instead of the L298N motor driver. Hope it helps. If still in doubt then you can ask.

@@UtGoTech ouh thanks sir this really helps me

👍

​@@UtGoTech hi sir can i have your number because i am a problem with it

Having problem*

6 volts to 12 volts

@@UtGoTech I am using a 9V battery(radio battery) to drive 4 dc motors, but the motors doesn’t rotate. Then I changed to 4 AA cells in series. Even then it doesn’t rotate.(I had given separate supply for Arduino through USB then it works)

You have to use a lithium based battery

😊

Can you tell from which application we can do the coding

You can use Arduino IDE

Yes you can use connector wires.

And sir can you tell how we can install motor shield library and then how can we write the code

To make the car move more faster

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

Use high RPM BO Motors for faster speed.

Nice idea

@@UtGoTech Thanks, but please make a tutorial quickly.

@MegaTechno ok I will try

Yes

You can but it from Amazon or Flipkart

Or from local shop

If you are using an arduino motor shield then you have to use arduino Uno or arduino mega. If you want to use board other than arduino UNO then you have to use different motor driver board. Check if the battery is fully charged and also check if the batteries are connected in series or not.

@@UtGoTech I HAVE ARDUINO MOTOR SHILED l293d + ARDUINO UNO which is NOT WORKING .. ALL THINGS ARE IN SERIES EVEN I USED 3 LI ION of 3.7volt battery with 1200mAH but at motor terminal the voltage is .3v and NOT WORKED...

Check if the motor shield and the motor driver shield is working correctly or not.

@@UtGoTech hello sir i checked and found it may be a battery problem single motor is running but using 2 motor than speed and all goes shut earlier i was using all four motor now tried with 1 and 2 motor it worked. should i go with more than 1200mAh for 3.7 volt or should use 3 3.7 volt li-ion battery.

You should use 2 18650 good quality Lithium ion batteries in series.

Yes

@@UtGoTech malayali ano

@kannanvlog4885 sorry I didn't understand

@@UtGoTech Kerala

?

Check battery voltage

If the battery is ok then check if the jumper is connected or not

@@UtGoTech My battery voltage is 3.7v and the jumper is also connected

You should be using two 18650 lithium ion cells which are in series to make it a 7.4 volt battery pack.

👍

Glad you think so!👍

Welcome👍

Yes that will be sufficient👍

Yes

@@UtGoTech but not work

Bluetooth module cannect & disconnect

Does your Bluetooth disconnects after giving command?

@@UtGoTech yes

Yes you can use different app but you have to map the buttons in the code

@@UtGoTech can you give suggestions how to map it

@marustudyeducation6518 you have to map button command codes from the app into the commands in the code.

Ok and thanks

Sir sorry, taking your time, I have tried this with 2 li-ion battery but through hw 130 l293d motor control I am not able to get the required voltage I have checked through multimeter the voltage I am getting is only 0.3 v rest thing is ok thn I increase the voltage upto 9 volt stil not get the required voltage at PWR pin I am getting 5.6 volt and Bluetooth hc05 not working but after shorting its working but not for long time And now the Bluetooth module automatically disconnected First through Your video I have joined the connection with thn go through the circuit diagram in both case it not working Even I downloaded the apk file but nothing is fruitful Should I change Arduino or motor driver or sth else What should I do kindly suggest!

Around ₹1000

Check battery voltage

If you have connected the + and - leads of the bluetooth module correctly the light will blink , also check if your wires are good with a multimeter

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

No this is just a project😊

Arduino Uno Motor Driver Shield 12 Volt Water Pump HC-05 Bluetooth Module 5 volt Single Channel Relay Board BO motors and wheels 18650 battery and holder

Thanks a lot 😊

Welcome Bro👍

You can use pins from A0 to A5 to communicate with the bluetooth module and use 2 servo motors

Glad it help👍👍

Either the speed setpoint is too low or the battery voltage is low

No

@@UtGoTech 😢

Welcome Bro 👍

That depends on the type of mobile charger

Ok

What type of battery are you using ?

If you are using AA batteries then your Bluetooth will disconnect after giving command.

I was using AA actually, which batteries should I use ?

@phoenixOP4103 I suggest you to use lithium based batteries

Sir I just connected 2 lithium ion batteries, it worked fine in start but now the Bluetooth module isn't getting power ( the red LED isn't glowing)

Have you installed the Adafruit Motor Shield V1 Library?

You can get 5v power through the arduino board

It seems that the microcontroller restarts due to voltage dips. The possible reason for the voltage dip is use of normal batteries. I suggest you use a lithium based battery.

@@UtGoTech Actually, my friends did it with normal batteries. my problem was like in the codes. After I wrote the servo code you gave, it said the installation was completed, but then it gave an error but I didnt't care , then I uploaded the code Otto Blockly, after running it, it became like this. I wonder if this would happen again if I uploaded the codes to a new Arduino Nano. And I wasn't wearing a buzzer, it has nothing to do with that, right?

No issues not having a buzzer. Try calibrating the servo motors.

I asked a lot of questions but how can I calibrate it?

You can use the example calibration sketch that comes with the library.

If you are planning to use 4 AA batteries then don't. Because AA batteries cannot provide enough power to drive 4 DC motors.

​@@UtGoTech Then can I use two lithium batteries

Yes you can use two Lithium batteries in series to 7.4V battery pack.

@@UtGoTech how much volt I have to use maximum

@UDSEDITZZ 12volt

Connect the IR sensors in A0, A1, A2 & A3

Have you installed the Adafruit Motor Shield V1 Library through Library Manager. What specific error, please share...

You have given Power to both Arduino and motor driver but have you removed the jumper in the motor shield.

Have you removed the jumper in the motor driver shield

@@UtGoTech No sir, we removed that when we were uploading the code. But we didn't removed it when we were trying to operate it with Bluetooth.

Sir can you recommend a specific battery that we should use to power the 4 motors of 12v with 200 rpm. So that we can ensure that we are not overloading the batteries.

If you are using separate power then you have to remove the jumper.

Yes
