This is a door with fingerprint lock demo that found by acrylic, Seeeduino and some other electronic modules~
First, you should enroll your fingerprint. Long press the button, then it'll go into enroll mode. there will be some information print in the lcd, just follow it.
Then it can work now.
Put your finger on Grove - fingerprint sensor, if your finger have been authorized, Servo will turn a certain angle, then the door open. When the door was close, the Grove - Infrared Reflective Sensor can detect it, then the servo will close the door.
