obstacle avoiding robot using arduino inTelugu

hey guys welcome to meworkstelugu in this we know about how to make a obstacle avoiding robot using Arduino

making video:

watch the below video to batter understand to do this project.

obstacle avoiding robot circuit diagram:

connect the all the components as show in below circuit.

obstacle avoiding robot code : 

int trigPin = 2;      // trig pin of HC-SR04

int echoPin = 3;     // Echo pin of HC-SR04

int revleft4 = 8;       //REVerse motion of Left motor

int fwdleft5 = 9;       //ForWarD motion of Left motor

int revright6 = 10;      //REVerse motion of Right motor

int fwdright7 = 11;      //ForWarD motion of Right motor

long duration, distance;

void setup() {

  

  delay(random(500,2000));   // delay for random time

  Serial.begin(9600);

  pinMode(revleft4, OUTPUT);      // set Motor pins as output

  pinMode(fwdleft5, OUTPUT);

  pinMode(revright6, OUTPUT);

  pinMode(fwdright7, OUTPUT);

  

  pinMode(trigPin, OUTPUT);         // set trig pin as output

  pinMode(echoPin, INPUT);          //set echo pin as input to capture reflected waves

}

void loop() {

  digitalWrite(trigPin, LOW);

  delayMicroseconds(2);   

  digitalWrite(trigPin, HIGH);     // send waves for 10 us

  delayMicroseconds(10);

  duration = pulseIn(echoPin, HIGH); // receive reflected waves

  distance = duration / 58.2;   // convert to distance

  delay(10);

    // If you dont get proper movements of your robot then alter the pin numbers

  if (distance > 19)            

  {

    digitalWrite(fwdright7, LOW);                    // move forward

    digitalWrite(revright6, HIGH);

    digitalWrite(fwdleft5, HIGH);                                

    digitalWrite(revleft4, LOW);                                                       

  }

  if (distance < 18)

  {

    digitalWrite(fwdright7, LOW);  //Stop                

    digitalWrite(revright6, LOW);

    digitalWrite(fwdleft5, LOW);                                

    digitalWrite(revleft4, LOW);

    delay(500);

    digitalWrite(fwdright7, LOW);      //movebackword         

    digitalWrite(revright6, HIGH);

    digitalWrite(fwdleft5, LOW);

    digitalWrite(fwdleft5, LOW);  

    delay(500);

  }

}
