Circuit Diagram

A) IR Proximity sensor connections:
1. Connect OUT of inner marker (Sensor) to Arduino's digital pin 6.
2. Then connect the OUT of middle marker (Sensor) to Arduino's digital pin 7.
3. Same as inner and middle connect the OUT of outer marker (Sensor) to Arduino's digital pin 8
4. Then connect OUT of NRI (No Return Indication sensor) to Arduino's digital pin 10.
5. Connect the GRD i.e. (ground) of all sensors to Arduino's pin ground.
6. Connect VCC of all sensors to Arduino's pin of +5 V.

B) LED's connections:
1. Connect +ve terminal of inner marker (LED) to arduino's digital pin 4.
2. Then connect the +ve terminal of middle marker (LED) to Arduino's digital pin 2.
3. Connect the +ve of outer marker (LED) to Arduino's digital pin 3.
4. After that connect all the -ve outer marker (LED) to Arduino's pin ground.

C) Buzzer connection:
1. Connect one terminal to Arduino's digital pin 11.
1. Connect another terminal to arduino's Pin GRD.

Code For Motor Part

Arduino
int en = 11, in1 = 7, in2 = 8; 

void setup() {
// put your setup code here, to run once:
pinMode(en, OUTPUT);
pinMode(in1, OUTPUT);
pinMode(in2, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(in1, LOW);
digitalWrite(in2, HIGH);

analogWrite(en, 96);

delay(14000);

digitalWrite(in1, LOW);
digitalWrite(in2, LOW);

delay(5000);

digitalWrite(in1, HIGH);
digitalWrite(in2, LOW);

analogWrite(en, 180);

delay(10500);

digitalWrite(in1, LOW);
digitalWrite(in2, LOW);

delay(8000);
