How to make a LINE FOLLOWING WITH OBSTACLE AVOIDING ROBOT/ ARDUINO LINE FOLLOWING ROBOT/ smart robot

[@hassanarif127]

can it work with only two motors and wheels?

[@MAKERQ]

Hassan Arif yes it will work with 2 wheels

[@hassanarif127]

Thanks i tried and it works. Although i must say that the code had a few extra things which were not needed at all (at-least not in my case) so i made a few modifications to the code and now it works like a charm :) *Thanks Again*

[@neilmitra4627]

Excuse me, if it is possible could you please send me the edited code ( in the comment section here)

[@hassanarif127]

Well i edited the code for only two motors at first, but later on i added two more motors for which the code provided by makerQ worked perfectly. All i edited in the code was the delay timings, and deleted a while loop, not any other major modification that i can remember, but unfortunately i don't have that code anymore, but if you can tell me the problem you're facing with this code i might be able to help.

[@neilmitra4627]

So the thing that is happening is that my wheels are continuously moving backwards, unable to follow a line, and unable to avoid obstacles, what I did was that I just removed the while loop from the code giving me this: #include //Ultrasonic sensor function library. You must install this library int vSpeed = 110; int turn_speed = 230; // 0 - 255 max int t_p_speed = 125; int stop_distance = 12; int turn_delay = 10; //HC-SR04 Sensor connection const int trigPin = 11; const int echoPin = 12; //L293 Connection const int motorA1 = 3; const int motorA2 = 4; const int motorAspeed = 5; const int motorB1 = 7; const int motorB2 = 8; const int motorBspeed = 6; //Sensor Connection const int left_sensor_pin =9; const int right_sensor_pin =10; int turnspeed; int left_sensor_state; int right_sensor_state; long duration; int distance; void setup() { pinMode(motorA1, OUTPUT); pinMode(motorA2, OUTPUT); pinMode(motorB1, OUTPUT); pinMode(motorB2, OUTPUT); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); Serial.begin(9600); delay(3000); digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); duration = pulseIn(echoPin, HIGH); distance= duration*0.034/2; Serial.print("Distance: "); Serial.println(distance); left_sensor_state = digitalRead(left_sensor_pin); right_sensor_state = digitalRead(right_sensor_pin); if(right_sensor_state == HIGH && left_sensor_state == LOW) { Serial.println("turning right"); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,LOW); digitalWrite(motorB2,HIGH); analogWrite (motorAspeed, vSpeed); analogWrite (motorBspeed, turn_speed); } if(right_sensor_state == LOW && left_sensor_state == HIGH) { Serial.println("turning left"); digitalWrite (motorA1,HIGH); digitalWrite(motorA2,LOW); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); analogWrite (motorAspeed, turn_speed); analogWrite (motorBspeed, vSpeed); delay(turn_delay); } if(right_sensor_state == LOW && left_sensor_state == LOW) { Serial.println("going forward"); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); analogWrite (motorAspeed, vSpeed); analogWrite (motorBspeed, vSpeed); delay(turn_delay); } if(right_sensor_state == HIGH && left_sensor_state == HIGH) { Serial.println("stop"); analogWrite (motorAspeed, 0); analogWrite (motorBspeed, 0); while(true){ } } if(distance < stop_distance) { digitalWrite (motorA1,HIGH); digitalWrite(motorA2,LOW); digitalWrite (motorB1,LOW); digitalWrite(motorB2,HIGH); delay(250); analogWrite (motorAspeed, 0); analogWrite (motorBspeed, 0); delay(500); digitalWrite (motorA1,HIGH); digitalWrite(motorA2,LOW); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); analogWrite (motorAspeed, t_p_speed); analogWrite (motorBspeed, t_p_speed); delay(900); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); analogWrite (motorAspeed, t_p_speed); analogWrite (motorBspeed, t_p_speed); delay(800); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,LOW); digitalWrite(motorB2,HIGH); delay(900); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); delay(700); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,LOW); digitalWrite(motorB2,HIGH); delay(650); digitalWrite (motorA1,LOW); digitalWrite(motorA2,HIGH); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); left_sensor_state == HIGH; while(left_sensor_state == LOW){ left_sensor_state = digitalRead(left_sensor_pin); right_sensor_state = digitalRead(right_sensor_pin); Serial.println("in the first while"); } digitalWrite (motorA1,HIGH); digitalWrite(motorA2,LOW); digitalWrite (motorB1,LOW); digitalWrite(motorB2,HIGH); delay(100); digitalWrite (motorA1,HIGH); digitalWrite(motorA2,LOW); digitalWrite (motorB1,HIGH); digitalWrite(motorB2,LOW); delay (500); } } void loop() { } But what's happening is that the motors/wheels continuously move backwards, unable to do anything else. Please help and thank you for the kind reply!

[@MAKERQ]

The while loop will stop the car , it is used to stop at the end, if your car is not moving delete that while loop

[@vimalabaskar2410]

MAKER Q I want a coad now pls

[@rizalagustian_k2373]

I'm using arduino uno for this project but the robot won't run at all, you said you have to delete the while loop first but I don't know where the while loop is, please show me 🙏🙏

[@MAKERQ]

If it's not working delete the while loop in the code and try again

[@dhruvpanchal1359]

Bhai code ka link open kiya to no preview available aa raha h kya karr

bro motos are not rotating???

[@vishalshukla5363]

can you let me know if it drives in revers after completing the line in to point b and ten it comes back to point a in a line with obstacles.

sir i want to make all in one .bluetooth controlled +line following + obstacle avoidance ..please help in code or make a video of all in one ..

[@TheDutchGamingBE]

You just have to buy a bluetooth module, connect it to the arduino, compile a bluetooth app to control the car. After all that, compile a code for the arduino so that the bluetooth module on the car can give orders to the arduino board that controls the car
