//need a serial port to communicate with the GT-511C1

SoftwareSerial gtSerial(8,7); // Arduino RX (GT TX), Arduino TX (GT RX)

void setup (){

Serial.begin(9600); //serial connection to processing app.

gtSerial.begin(9600); //for communicating with the GT-551C1

}

WORKING

In this security system using fingerprint sensor we used GT511C finger print sensor , in this we have to enroll the fingerprint using SDK software in this we can enroll up to 200 fingerprints. When we apply fingerprint

The gate will for the delay we provided and then it will close. The capacitor is used to reduce the spike voltage.
