In this video, you can learn how to design and troubleshoot a password-protected door lock using Arduino UNO, an LCD Display and a Servo-Motor. This project also requires a 4 by 4 or 4 by 3 keypad for the iteration of the user and the mechanism.
We are implementing this project on Tinker CAD first to troubleshoot the errors as this project involves a little bit of a complicated programming due to multiple functions. On the other side, the hardware for this project is also very complicated due to the interaction of an Arduino, LCD, Servo-motor and a Keypad!
This project is very useful as you can make one of them for each safe or doors of your house!
The programming for Arduino door lock with the interaction of a 4 by 4 keypad and password protection is available in this video including all the hardware!
