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);
    
      
    }
  }
