how to make a Obstacle Avoiding Robot using Arduino uno and L293d with HC sr04 Sensor

This information is processed by the Arduino, L293D motor control shield and ultrasonic sensor hc-sr04. If the distance between the robot and the obstacle is less than 20cm, the Robot stops and scans in left and right directions for new distance using Servo Motor and Ultrasonic Sensor. If the distance towards the left side is more than that of the right side, the robot will prepare for a left turn. But first, it backs up a little bit and then activates the Left Wheel Motor in reversed in direction.

Great, Your code is working well. I already completed my University project with this rover using your code. Thank You very much friend from Sri Lanka. Good Luck 🙏

hello is there a way to use this l293d shield together with the nrf24l01 module. because the shift register integrated on the shield uses miso mosi sck pins.

bhai very nice vedio but one confusion is with code AF_DCMOTOR motor1(MOTOR_1, MOTOR12_64KHZ) HERE inside the bracket we motor_1 is the port number and motor12 is the channel with frequency of 64khz .Are all the ports to which motors are connected is it channel1 and 2 or motors connected to port3 and 4 are in channel 3 and 4 plz clarify the doubt be

Sir, Is it possible that I can make the connection to the lcd module between line follower robot project as well as in the circuit diagram and the coding of the Arduino IDE software?

[mustafasucu]

you are doing very good work, congratulations brother from pakistan.

[FarahN-xgvt]

Heyy great work, how can I make the same object avoider but with 3 ultrasonic sensors instead of the servo motor? What changes should be in the code?

[SoumenMishraKansbahal]

Bhai need your help, obstacle robot mera kaam nahi kar raha hai, bas ek jagah ghum raha hai aur servo idhar udhar ghum raha hai, pls help

[frazfahad]

Sir, can you tell me which area do you live in Islamabad, I want to meet you.

[evounknown]

I have done the same but here servo seems to rotating and uncontrolled and the gear motors don't move kindly help me to sort out this problem 😭🙏 I've bought all materials for school project but car is not working

[HarshGArt]

Bhi code apply kar raha hu to error kyu bata raha hai please help me🙏😭

[duyanhao]

hi i have a trouble. when I provide battery supply in motor driver then auduino is not on what's the issue. the ardunio only work if i use usb and don't work if i use battery supply for motor driver. I use usb only ardunio green led work and motor don't have green led, i use battery 3, 7V*2 only motor shield green led work and ardunio don't work. What wrong with me

[Amankumar-jpsf]

Kya aisa hi koi project bina arduino se ban sakta hai

[swaritvaishnav]

i made this project yesterday as per to your video but the motor was not working was this because of the power issue?
is 1200 mah and 3.7 v battery okay ?

[sowunmikorede]

I successfully uploaded the code on my Arduino uno board and i noticed that the tires are moving in two different directions. The two front tires are moving clockwise while, the two back tires are moving anit-clockwise. please what could be the problem?

[rizwansaeed]

assalam o alaikum
mere paas jo l293d driver ha us men ultra sonic sensor connect karne k liye connectors nai lage
sirf khaali jaga ha
mere paas female jumper k liye extra connectors pare han kia wo lag jayen ge
please reply de den
agar kisi aur ko bhi pata ha to wo bhi guide karen thankyou in advance

[jishabenny]

Can I use Arduino UNO R3 SMD Atmega328P Board - Clone Compatible Model, plz reply

[RabeyaBasry-ny]

Thank you, I have made this project.

[ZhydGonzaga]

not working it says
exit status 1

Compilation error: 'AF_DCMotor' does not name a type
