The complete arduino door lock code can be found at the bottom of this page. Whether from the inside or outside whenever the door is locked the leds turn red and whenever the door is unlocked they turn green. From inside you can press the reset pin on the arduino to lock or unlock the door. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.

First of all we will make the connection to the 4 4 keypad. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. Conclusion in this tutorial post we learnt how to set up a fingerprint sensor and how to use it with our arduino you can use this knowledge to control a door lock and led or any apparatus that you want to control.
