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.
