We go to File -> Examples -> Adafruit Fingerprint Sensor Library -> Enroll. First of all we need the Adafruit Fingerprint library, the Adafruit GFX library and the Sumotoy’s library for the display.įirst of all we have to upload the enroll example to our Arduino board. Let’s now see, the software side of the project and how to enroll our fingerprints to the module’s embedded memory in order to recognize them. 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! If I place another finger on the sensor, the project does not unlock the screen. If my girlfriend places her finger on the sensor, it also recognizes her, and displays a welcome message with her name. When I place my finger on the sensor, it recognizes my finger, turns the fingerprint icon green and it welcomes me. The project asks for a valid fingerprint in order to unlock. 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. In order to demonstrate a simple use of the sensor a built this simple project. 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. Without any further delay, let’s get started! Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor module.
