How to make a LINE FOLLOWING ROBOT / arduino line following robot 

Bro jaldi se naya code dalo

send the correct code pls

Sir new code snd kr dyyy

New code

d

Yes

No we can't

S

yes two sensors are of two sides let the robo knows that it will not away from the path

Mine too

Iss chutya we have shayad ullu banaya hai it's fake project Mera bhi workbnahibkar raha

he already uploaded the program. it is n the description

Yes

Bhoopathy G I used fritzing software to draw the schematics.

MAKER Q ok thanks

int vSpeed = 110; // MAX 255 int turn_speed = 230; // MAX 255 int turn_delay = 10; //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 left_sensor_state; int right_sensor_state; void setup() { pinMode(motorA1, OUTPUT); pinMode(motorA2, OUTPUT); pinMode(motorB1, OUTPUT); pinMode(motorB2, OUTPUT); Serial.begin(9600); delay(3000); } void loop() { 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){ } } }

Saumtally Shahanah Wardah remove the while loop in the code

And try it
