The face also includes a keypad for when the other functions are out of use or to give access to someone else. The inside contains an Arduino Mega as the controller which is connected to a battery, a servo motor, and a wifi receiver/transmitter, this means the door can be opened and closed from anywhere in the world with available wifi connection. The outside of the door uses a simple wood frame with black acrylic glass and an LED ring around the door nob which lights green to indicate when the door is open and red to indicate its closed or the password or fingerprint is incorrect. The inside of the door also has a wood frame with black acrylic glass which shows a nice opening to see how the gears open and close the lock. The battery is removable to allow charging, and in the case the battery runs out of charge the dc power which is optionally plugged in will keep it on.

| OBJECTIVE |

The lock uses low cost 3d printed parts to function as a cylinder lock for european door lock body, mortice, to lock and unlock the door. The design uses a servo as an actuator with a system of gears o turn the nob back and forth locking and unlocking it. It can be opened using a variety of methods, the top contains a fingerprint sensor and the face contains and rfid/nfc reader which uses your phone or a rfid card or tag to open.

The lock uses a camera for survailance on who enters and exits and when they do along with facial recognition to help doing so.

| PROTOTYPING WIRING |

 

Designed to work with my other designed smart home projects it uses an ESP32 CAM connected to the main Arduino Mega to open the door using a mobile device in addition to the fingerprint scanner, keypad, nfc, and the vibration piezo sensor coded knock. With the reed switch, camera, capacitive touch sensor, LED ring, lithium battery charger, 18650 batteries, SPDT switch, piezo buzzer, and 5V DC jack to power it all. The 18650 batteries are to act as a back up incase the power goes out so the DC jack charges the batteries when it is plugged in and when it is not it uses the batteries to stay on for at leat 3 days. On top of this the 3D printed enclusre and case with M3 screws and black acrylic glass.
