Abstract

This device is an automated door lock attachment for an existing deadbolt-locked door. The device takes an exterior RFID input and can both lock and unlock the door. The device also implements an exterior doorbell switch where a guest can turn on a buzzer, and an interior switch for the operator to unlock the door from the inside. The front interface of the device is pictured in Figure 1; the working mechanism to turn the lock is pictured in Figure 2, and the housing for the processing and wirings is pictured in Figure 3. The logic is implemented using a PIC16F88 and Arduino Nano. The code implemented on the PIC is located in Appendix A1.1; the code for the Arduino is in A1.2; and the wiring diagram that ties the entire design together is in A2.
