Now we have the final schematic and code. All we need is the 3D printed case that you could downlaod froma link below and 3D print it. Fit the LCD in place and the Arduino MEGA using m3 screws. Then using wires we make all the connections and our door lock is ready. There is space for 3 push buttons as well.

Now the case and project is ready. I hope that you've enjoyed the tutorial and that you have learned something new. Now you know how to use the fingerprint sensor, RTC module and the SD card module and create a black box door lock with fingerprint security. Consider helping me on PATREON.
