In the wifi and password space in the code should we enter the wifi and password credentials of which the system is connected or does the esp 32 cam module has it's own wifi?
const char* ssid = "MyWiFiCar"; const char* password = "12345678"; These lines in the code are these the credentials of the wifi signal produce by the esp 32 cam module or are these the credentials of an existing wifi network
The code is getting uploaded properly But when I apply the voltage the four motor start moving And I'm not getting the wifi signal what might be the reason
#hashincludeelectronics Thanks For This Detailed Project Sir.. It Worked in The First Attempt. Code Explanation were Awesome. Pin Diagrams Helped a Lot. Thanks a Lot Sir.
In this project esp32 works in AP mode which creates local WiFi network itself . And our mobile can connect to it . We don’t need any internet for this.
Thanks for the great and very detailed project. Followed it literally and worked in the first attempt (my granddaughter thinks I am a genius!). However, when using the robot, sometimes the image freezes on the screen of the cell phone. Is there a probable cause for it and a way to fix the freeze?
I am glad that you liked the video and it worked 🙂👍🏻. Not sure if you already changed one setting as suggested in video . We need to set something like MAX_QUEUE_MESSAGES to 1 in the websocket library. I have described in the video . Please set it and re upload the code if not done previously. That should solve the problem .
Just that I don't understand it when I didn't make any changes there :-( Editing the code won't be a problem, but unfortunately I have no idea where to rewrite it.

@@TheOmareichon first of all please do not use IO16 pin . It is internally used by some other functionality for psram. You can try using some other pins . Also for passive buzzer to work you need to write some pwm values to it . Not sure if digitalWrite will work. You can use the ledcWrite same which I used for controlling light . Are you using active buzzer ?
Is there a way to make the app work on PC browsers? I can connect to the app on PC but unable to control the movements of the robot. The slider for the light works tho!
Yeah this app only works on touch device . For making it work on PC , we will have to make changes in the code and add events for mouse click which will take time and also needs testing . If you can make changes in code and test properly that would be nice . Check for mouse events on internet .

Hello, first of all, I would like to thank you very much for the incredibly detailed and helpful video. I have a question: Is there any difference when uploading code from Arduino compared to uploading code from ESP32-CAM-MB? Hope to get a reply soon! Thank you.
Nice video bro, all explained well. I have one question. I already try your project and everything is fine until i control the car. The wifi disconnect after the car move a bit. Is the cause from my battery?
Is it possible to use LCD touchscreen with ESP32 for controlling this car and getting video from it? To avoid using cellphone...? Like WT32 SC01 plus or even T-deck with mounted trackball?
You need to have touch screen device and also internet browser to open this app and work properly . If your LCD screen device supports all these then yes you can use 👍🏻👏🏻
Straightforward using the HC-SR04 in the loop doesn't work. Blinking without delay makes the WIFI unstable. Using a second ESP32 with distance calculation and relais between LN293 and the motors works, but is a bit clumsy solution. I'll continue my research. Perhaps multitasking with the second core in the ESP32 is a possibility.
Hello, I did everything like in the movie and it works great, but I have a problem with the image from the camera, or the pmalu refreshes or not at all and the image is still
There is one setting which says MAX_MESSAGE_QUEUED that needs to be changed . Could you please check that part in the video ? It’s must needed . It will resolve your issues .
There's a small problem... How to connect 2 cables into io12 The EnA and EnB is 2 different ports... So do we cut the jumper cable and then connect the 2 and then put it together?
Thank you very much for checking out the video 👍🏻👏🏻. This project creates its own wifi network hence the ssid . You don’t need to use your home wifi credentials.
Hi sir can you tell me how can I setup esp32 after uploading the code that ssid and password thing in the code and I didn't understand the app thing that u told in the video
hello bro thanks for this tutorial and i have a little error that is wifi is work 6 sec then desconenct and only 1 button is working so what is the solution?
Perfect presentation although you speak very rapidly. Many thanks for this project. Would it be possible to add a collision protection using an HC-SR04 US sensor and defining 10 cm or so as minimum distance?
Thanks for checking out the video 👍🏻👏🏻. Yes we can add ultrasonic sensor in this project . I have not used this in any of my esp32 project yet . I generally use NewPing library in Arduino boards for ultrasonic sensor . For esp32 NewPing library will not work . You need to read the ultrasonic sensor using pulseIn method .

@@TheOmareichon that’s great 👌🏻keep it up . If motors are rotating in opposite direction then reverse the wires of motor connected to L298N driver accordingly.
@@hashincludeelectronics Hi again sir, I make some changes to the program cause I'm trying to put it on a buzzer in the middle box of the mobile app, but it doesn't work propely :c could you please see if there is a mistake in the code ? I'm gonna put the lines/sentences that I aggregated:
///
#define BUZZ 16 ////define the function
///
⇦
⚟ /////middle botton with a symbol
⇨
///
void buzzer(int inputValue)
{
switch(inputValue)
{
case 1:
digitalWrite(BUZZ, HIGH);
break;
case 0:
digitalWrite(BUZZ, LOW);
break;
}
}
///
if (key == "MoveCar")
{
moveCar(valueInt);
}
else if (key == "Speed")
{
ledcWrite(PWMSpeedChannel, valueInt);
}
else if (key == "Buzzer") ///make the key
{
buzzer(valueInt);
}
else if (key == "Light")
{
ledcWrite(PWMLightChannel, valueInt);
}
}
////
moveCar(STOP);
pinMode(LIGHT_PIN, OUTPUT);
ledcAttachPin(LIGHT_PIN, PWMLightChannel);
pinMode(BUZZ, OUTPUT); ///define the pin state/mode
///
I hope you can help me, I'm using the output IO16 of the ESP32 and making other things to make it work, greetings from Mexico (Y)
@@TheOmareichon first of all please do not use IO16 pin . It is internally used by some other functionality for psram. You can try using some other pins . Also for passive buzzer to work you need to write some pwm values to it . Not sure if digitalWrite will work. You can use the ledcWrite same which I used for controlling light . Are you using active buzzer ?
Is there a way to make the app work on PC browsers? I can connect to the app on PC but unable to control the movements of the robot. The slider for the light works tho!
Yeah this app only works on touch device . For making it work on PC , we will have to make changes in the code and add events for mouse click which will take time and also needs testing . If you can make changes in code and test properly that would be nice . Check for mouse events on internet .
@@hashincludeelectronics ooh i see, i just tried on a touchscreen PC and it worked hahaha, thank you! you really help with my project. Edit: I just checked another video where instead of using ontouchstart, they use onclick. I wonder if we can use both in the same code. Edit 2 : yooo it works! i just added onmousedown and onmouseup next to ontouchstart and ontouchend functions
@@kahfiwirmandy well done 👏🏻👏🏻👏🏻. Thank you very much for sharing 👌🏻
@@hashincludeelectronics no man, i thank you for sharing this video, without you i wont be able to complete my project! you're the best! Edit: this is what i did ⇧
Can I use four Li ion battery (3.7v 1200 mah each) in series
Yes you can 👍🏻👏🏻
Hello, first of all, I would like to thank you very much for the incredibly detailed and helpful video. I have a question: Is there any difference when uploading code from Arduino compared to uploading code from ESP32-CAM-MB? Hope to get a reply soon! Thank you.
@@luquorus8061 it’s same 👍🏻👏🏻
@hashincludeelectronics but I am using the 18650 lithium ion 3.7v 2600mah 2 batteries
Make sure those batteries are charged fully 👍🏻👏🏻
Which device can be used in the place of arduino
You can use any ftdi module for code upload 👍🏻👏🏻 .
sir we can fix Antenna to esp32 cam to increase the range
Please do it and share the experience 👍🏻👏🏻
Nice video bro, all explained well. I have one question. I already try your project and everything is fine until i control the car. The wifi disconnect after the car move a bit. Is the cause from my battery?
Thanks for checking out the video 👍🏻. Yes . Please use only rechargeable battery .
Instead of zippy 1500 mah dc battery
We can use the li ion battery?
Yes you can 👏🏻👍🏻
Do i use lipo 7.4v and arduino chip smd? Please answer me, thanks.
Nope . This project needs esp32cam module .
Is it possible to use LCD touchscreen with ESP32 for controlling this car and getting video from it? To avoid using cellphone...? Like WT32 SC01 plus or even T-deck with mounted trackball?
You need to have touch screen device and also internet browser to open this app and work properly . If your LCD screen device supports all these then yes you can use 👍🏻👏🏻
So, web video server or access point is the only way to capture video from esp32cam?
Straightforward using the HC-SR04 in the loop doesn't work. Blinking without delay makes the WIFI unstable. Using a second ESP32 with distance calculation and relais between LN293 and the motors works, but is a bit clumsy solution. I'll continue my research. Perhaps multitasking with the second core in the ESP32 is a possibility.
Good observation and finding . I need to use HCSR04 in esp32 for my next project. I am going to try it 👍🏻👏🏻
What is mean exit status 1 error and it shows while uploading program to esp32 cam through Arduino Uno..can you find out this?
Can you control it without connecting to the same network? Example rc car on wifi, phone on mobile data
Sorry I did not get your question properly .
Please make and share full video of small parts also these things are difficult for begginer because of these I am requesting to you
You can find many resources online to help you with small parts. 👍🏻👏🏻
ledcSetup' was not declared in this scope; did you mean 'ledc_stop'? How to Solve
Please install lower version of esp32 board 2.0.16 👍🏻👏🏻
Bro, is it work?
@@KhantWaiYan-q3l yes
Hello, I did everything like in the movie and it works great, but I have a problem with the image from the camera, or the pmalu refreshes or not at all and the image is still
There is one setting which says MAX_MESSAGE_QUEUED that needs to be changed . Could you please check that part in the video ? It’s must needed . It will resolve your issues .
I have one doute that when you started coding then how camera car heading came?
Don’t worry about heading . Just open the code and copy paste in your Arduino IDE .
There's a small problem... How to connect 2 cables into io12
The EnA and EnB is 2 different ports... So do we cut the jumper cable and then connect the 2 and then put it together?
Yes exactly 👍🏻👏🏻
Hi
I have to ask that
After uploading the code in ESP 32 using Arduino Uno
You remove the Arduino Uno or we want this in the car ?
Plz reply
We need to remove Arduino Uno 👍🏻👏🏻. If you have any doubt then please check the video slowly and carefully 👍🏻👏🏻
@@hashincludeelectronics thanks 👍 for quick response
@@nmfb-67shivamtripathi42 welcome 🙏
If I add external antenna 📡 what will be the best range with no cam lag
Frankly speaking I have not tried that . I would be really waiting for the results if you can share once antenna is added 👍🏻👏🏻
Bro you should make more videos you are so good
@@selvaff3734 thank you very much 👍🏻👏🏻. Yes I will be back with videos soon 👍🏻
Great project really enjoyed. Where does the wifi from "MyWifiCar" come from? Also could we replace it with our own wifi to make it stronger? Thanks
Thank you very much for checking out the video 👍🏻👏🏻. This project creates its own wifi network hence the ssid . You don’t need to use your home wifi credentials.
sir that middle button takes images or it only records video.Not taking photo in the video.please guide me how to take photo .
That middle button does not do anything 😜
sir then how to take photos and upload to mobile
please help us in taking photos and uploading to our mobile folder.😢
Bro for simulation which software should we use
You need to directly open the car app on your mobile 👏🏻👍🏻
Bro I need to Perform simulation on software such as proteus and other but all components are not available on 1 software
@@305adityabarai8 unfortunately I am not aware of this simulation 👍🏻
Bro can you ask someone🙏🙏
Hi sir can you tell me how can I setup esp32 after uploading the code that ssid and password thing in the code and I didn't understand the app thing that u told in the video
If you edit those 2 lines, what should you do?
How many programs it have
And which module to dump
Please check the video for full details👏🏻👍🏻
Have you used SD card in esp32 camera??
Not yet .
Is it possible if i use x6mini camera instead of esp32 cam?
I am not aware about that cam module 👍🏻👏🏻
is threre any led on th eesp32 board that indicates the power...?
I believe so 👍🏻👏🏻
should we use the same IP address or should we generate one for ourselves ?
Yes the IP Address should be exactly same as shown in video. You can change SSID and password if needed as you like Or you can keep it same.
hello bro thanks for this tutorial and i have a little error that is wifi is work 6 sec then desconenct and only 1 button is working so what is the solution?
May be there is power issue . Please use rechargeable battery and try 👍🏻👏🏻
Perfect presentation although you speak very rapidly. Many thanks for this project. Would it be possible to add a collision protection using an HC-SR04 US sensor and defining 10 cm or so as minimum distance?
Thanks for checking out the video 👍🏻👏🏻. Yes we can add ultrasonic sensor in this project . I have not used this in any of my esp32 project yet . I generally use NewPing library in Arduino boards for ultrasonic sensor . For esp32 NewPing library will not work . You need to read the ultrasonic sensor using pulseIn method . Please check more details on internet in this 👍🏻👏🏻
Can we code on camera before wiring and then attach wires
Yes you should do that 👍🏻
@@hashincludeelectronics Thank you
you are really great and hardworker I am also a youtuber and i know that i have also made you arduino hand following robort
