Fingerprint Sensor Servo Lock — Arduino Access Prototype

Fingerprint Sensor Servo Lock was an early Arduino access-control experiment from 2021. The project connected a fingerprint sensor with servo movement, testing how biometric-style input could be used to trigger a physical locking or unlocking action. The code checks fingerprint input, searches for a stored fingerprint match, and moves the servo when a valid fingerprint ID is found. It is a focused prototype that fits Parth's broader early interest in electronics, identity-based access, and physical automation. This project is useful because it shows early exploration of identity-based control. It also connects sensor input, recognition logic, and physical movement — a pattern that later appears in more complex access-control and automation ideas.

The project explored how fingerprint recognition could be connected to a physical access mechanism. Instead of using only a button or manual switch, the system used fingerprint matching as the trigger for servo movement.

The Arduino sketch initializes the fingerprint sensor, reads a fingerprint image, converts it for matching, searches against stored templates, and moves a servo when the fingerprint ID is valid.

Parth wrote the Arduino control logic, connected fingerprint sensor input with servo output, and tested a simple biometric-access automation flow.
