| To implement the project in a physical format, a servo motor is used which performs the opening/closing of the door. To actuate the servo motor, and thus open the door, a keypad is added, through which the user can enter the correct password, as well as an RFID card communication module, where, using the correct card, the door can be opened. | To implement the project in a physical format, a servo motor is used which performs the opening/closing of the door.

This functionality was later abandoned, since the two load cells used were either too hard to trigger (50kg, 3 wires) or had no pins remaining to be wired to the Arduino board (10kg, 4 wires). Right now, the 50kg is present but not connected, it only is used as part of the locking mechanism. |
| The alarm system is activated if the door is forced or 3 incorrect passwords have been entered consecutively 3 times, with the user having three attempts to open the door. Once the alarm system is activated, a buzzer will emit a loud audible signal, which can only be stopped by using the correct RFID card. | The alarm system is activated if the door is forced or 3 incorrect passwords have been entered consecutively 3 times, with the user having three attempts to open the door.
