Introduction: Fingerprint Sensor With Arduino

About: i am electronic Hobbyist. I like to make the things and also make it available to people who need it. Please visit and subscribe my youtube channel for more Embedded related videos.…

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.

Step 1: Required Components

GT511c3 in India-

GT511c3 in UK -

GT511c3 in USA -
