Keypad Smart Door Lock with OLED | Arduino

#Arduino #SpeedArduino Amazon Affiliate: https://amzn.to/3h7Sth3 In this project, we will be making a "Keypad Smart Door Lock with OLED." There is a standard default password, "12345," and a default master password, "09876," in this smart door lock. Both the standard and the master password can be changed in the settings displayed on the OLED display. To change the standard or master password, you will have to enter the master password, go in the settings, and then change the password from there. Once you enter the standard password, the servo rotates. You can connect the servo to a lock, and then the servo will rotate, locking or unlocking the lock.
