This is a library for interfacing with the Adafruit optical Fingerprint sensor. The sensor is designed to work with TTL Serial communication, requiring only 2 pins to interface.
This library provides a set of functions to communicate with the Adafruit Fingerprint sensor. It allows users to perform various operations such as enrolling fingerprints, searching for matching fingerprints, storing and deleting fingerprint templates, and controlling the built-in LED and Aura LED (if available).
To use this library, you'll need to connect the Adafruit Fingerprint sensor to your microcontroller using TTL Serial communication. You can use either Hardware Serial or Software Serial depending on your platform. Ensure that you have the necessary dependencies installed and that you include the library in your project.
- Verify password
