Hello, In this article we will see how to use fingerprint sensor with Arduino. With Fingerprint sensor you can add security and lock to your home, office, garage and many more. Not only about secuity, you can add use this module where you want in time and out time in the access restricted area.
We will be using GT511C3 Fingerprint module interface with arduino.
