“Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor module. Without any further delay, let’s get started! I always wanted to try a fingerprint sensor module in order to learn more about its technology and use it in some of my projects in order to add biometric security to them. In order to demonstrate a simple use of the sensor a built this simple project. I have hooked up the sensor to an Arduino Nano, and I also use the small but very fast 1.44 inch color TFT display. The project asks for a valid fingerprint in order to unlock. When I place my finger on the sensor, it recognizes my finger, turns the fingerprint icon green and it welcomes me. If my girlfriend places her finger on the sensor, it also recognizes her, and displays a welcome message with her name. If I place another finger on the sensor, the project does not unlock the screen. It works fine and you are going to see, you can build this project in less than 10 minutes! Let’s see how to achieve that!”
