How to make Arduino Obstacle Avoiding Car + Bluetooth controlled Robot Car || L298N
HTML-код
- Опубликовано: 7 мар 2020
- This project is designed to build a robot that automatically detects the obstacle on its path and guides itself whenever an obstacle comes ahead of it. This robotic vehicle is built, using Arduino UNO board. An ultrasonic sensor is used to detect any obstacle ahead of it. A motor driver IC and 2 DC motors are used for controlling the movement of the robot. A servo motor is also used in this project. The ultrasonic sensor is then mounted on the servo and by rotating the servo to different angles we will obtain the readings from the ultrasonic sensor in those angles. This will help the controller to detect the exact path to navigate. A Bluetooth module is also added to the project (which is optional ) in order to control the robot from your android phone when it is in manual mode.

HI! Do you have the Fritzing diagram on this project? (the one with the circuit diagram)
The CODE compiled with no errors, but you seem to forget the schematics on your project?
Great video 🌷 I do arduino videos but in Arabic ... nice work keep it up
At first it worked superb the project was absolutely fine but then something went wrong I couldn't find where the app received the information about the car which direction it is turning to but I just can't get to the manual mode.
awesome work and ty for sharing
Nice work! Have you tried the EPS32 for this sort of project?
it'll be included in an upcoming project...Thanks
Can we use ardiuno nano
the code in the description is a ds_store file , i cannot open it,can you help?
hello bro ,i am looking to build a car control robot via bluetooth module like yours but the other thing is i want to use the ultrasonic sensor module to calculate the distance between the car and obstruction, then order the car to stop or can't move forward. It is like making the car avoid collision with obstacles but still controlled by bluetooth. Can you help me with making arduino controller code? thank you
if i could understand your request well, once the car comes close to an obstruction it neither moves right or left but rather stops?
Nice Project ! But I have a doubt, can this arduino car avoid object even though when controling the car with mobile?
Please help me I want to make an arduino car which avoids object when controled with mobile. Please!
Great work, but i faced problem that the wheels didn’t work i used 4 motors and l298N shield motor. How can i fix it ?
Kindly make sure your connections are correct
check the state of your battery and make sure its charged and up to 9v minimum
Also check the power connection between the l298N, Arduino board 5v input and the battery
god bless you
thnx bro love you
Hi, great project. :D Can you please share the .aia file for the app inventor? Thanks
Can u give the correct diagram because the motor in videos use L298N but in diagrams use L293N.. the connection was not same
please send me to ashimieizwan@gmail.com
Can I use Arduino UNO R3 SMD Atmega328P Board - Clone Compatible Model ,plz reply
Yes you can, just make sure you use the same source code as well as wiring ,if you have to edit the wiring, make sure you do the same in the source code.
Salut svp je peux faire comme ce robot par L298D
How to get the code plz.Given link is not working
will this work obstacle avoidance and bluetooth controlling simultaniously
By 'simultaneously' please explain further
@@josharduino3241 will both work at same time?
Bro can i have ckt diagram or arudino code?
Brother can you give me the diagram and source code ?
Great project! I really like the way it tests the path before making a decision! I used 4 motors, so I had to make a simple change on the speed. Your APK is also great, but I would like to help you by making some modifications and improvements. Could you share your apk project? Thank you.
Thanks😊
You mean the raw .aia file right?
@@josharduino3241 Yes. The apk code and UI. Thanks.
JULIO, how did you changed the speed.
Can you give me your code, I am running it on 4 wheels
Is there a button that switch manual and automatic code in the application
Yes
bro which app is using for controlling car in
manual mode?
link to the app can be found in the description below
how you can switche btw Obstacle Avoiding and Bluetooth controlle
there is an option for manual and automatic on the app
How much max voltage we can apply?
9v you need to add resistor for bluetooth module if you are planning for more
hi, how can I copy Source code & Libraries to my computer IDE library?
u download from googledrive as zip file and open arduino library click as (sketch>include library>Add ZIP.library)
but it show:
Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Arduino Uno"
Specified folder/zip file does not contain a valid library
Invalid library found in C:\Users\Lenovo\Documents\Arduino\libraries

My connection of circuit same as your, the only thing i confuse is how to upload the code and add file to library
Im a newer of learn arduino, i really need your help!
my email is ybchang88@gmail.com
unzip the downloaded library and upload the library as a folder
Plz give the diagram
BUENAS NOCHES EL APK. ME INDICA QUE NO ES COMPATIBLE CON LA NUEVA VERSION DE ANDROID, PUEDE ACTUALIZAR LA VERSION DEL APK
Source code please! the given code does not open.
Download the files from the google drive link provided above.
Can someone help me to send me the real code please now please!!!!!
check your email
make sure your connections are in sync with mine..other than that i see no reason why it wouldn't work. Also check if all modules and components are working perfectly. The same goes with the new ping and servo libraray
@@josharduino3241 please send me too much needed
@@abhisheksalvi2413 ITS THE SAME AS LISTED IN THE DESCRIPTION
Jhanta kuch samajh aya
hello I have a problem with the code
#include tells me it doesn't exist
Add the newping library
