what do people make with this?

VIBE 1

Wire a fingerprint sensor to an Arduino connected to your keyboard to recognize different users.

VIBE 2

Set up a gaming setup where different players get different keyboard configurations based on fingerprint.

VIBE 3

Enroll and manage fingerprints over serial commands like 'A,3' to register and 'D' to delete all.

VIBE 4

Extend the firmware with custom commands and actions beyond basic recognition.
