Smart TollGate Barrier Using RFID Module

 Circuit:- 

Code:-

#include<Servo.h>

Servo servo;

int count = 0;  

char input[12];

void setup() {

  Serial.begin(9600);

 servo.attach(8);

 servo.write(0);

}

void loop() {

  if(Serial.available())

  {

    count = 0;

    while(Serial.available() && count < 12)

    {

      input[count] = Serial.read();

      count++;

      delay(5);

    }

    if(input[0] == '4' && input[1] == '0' && input[2] == '0' && input[3] == '0' &&

       input[4] == '3' && input[5] == '5' && input[6] == '0' && input[7] == '5' &&

       input[8] == '9' && input[9] == '1' && input[10] == 'E' && input[11] == '1' )

    {

      servo.write(90);

      delay(2000);

      servo.write(0);

    

      

    }

Automatic car parking using 2 IR sensors Part (2)

 Circuit:-

We are adding one more IR sensor on the 10th pin of Arduino

Code:- 

#include<Servo.h>

int IR1 = 10;

int IR2 = 11;

Servo servo1;

Servo servo2;

void setup() {

pinMode(IR1,INPUT);

pinMode(IR2,INPUT);

servo1.attach(8);

servo2.attach(9);

servo2.write(0);

servo1.write(120);

delay(1000);

}

void loop() {

  if(digitalRead(IR1)==LOW && digitalRead(IR2)==HIGH)

  

 {

  servo2.write(90);

 servo1.write(0);

  

  

 

 }

 else if(digitalRead(IR1)==HIGH && digitalRead(IR2)==LOW)

 {

   servo2.write(0);

  servo1.write(120);

 }

}
