Schematic circuit above shows connections of the prototype for two-step verification door lock system. We are using Cirkit Designer Software 1.3.3 that embedded with various components to present the detailed connection of our project, except for NUCLEO-F411RE Board and ESP32C3 Super Mini, which we customize the component's pins and upload it into the software privately.

The other components that displayed in this schematic circuit are including RFID-RC522, Rotary Potentiometer, Piezo Buzzer, LCD Display (16 Pins), Breadboard, Keypad 4x4, Resistors, LEDs and ESP32-CAM.

The layout of the project's circuit, connected with the outputs' components is shown in the picture above. The main layout is connected to Laptop using USB-A to Mini USB Cable, providing sufficient power supply to the circuit. Full demonstration video for this project is shown in the Project Outcomes & Accomplishments' section.
