Скачать или смотреть Arduino Password Lock Security System With Servo STEM SOS PBL

The main purpose of my project is to show you how to make a cheap electronic keypad door lock using an Arduino UNO board, a keypad, and a servo motor. By using this system you will be able to unlock and lock a door in a very unique and creative way. By hooking up the 8 pin keypad to the Arduino, as well as a green/red LEDs, and also a servo motor, you can lock and unlock anything using a 3 digit code. Connecting the servo motor to your door knob could be a very creative way to add more security. This servo motor will work only if you put the 3 digit code that you assign it. For example: If your code is "159" when you type those three digits, the green LED will turn on making the servo motor rotate. Then the door will be unlocked without the necessity of a key. When you want to lock your door and secure it, type the "*" button to reset the servo motor. This will turn the red LED on, locking your door. I hope you enjoy the video!

STEM SOS Model:
STEM SOS is a rigorous, interdisciplinary, standards-focused, and engaging STEM teaching an approach that is teacher-facilitated, student-centered and directed through sets of the project- and inquiry-based (P&IBL) projects. This PBL approach is to maintain the focus on standards-based teaching while enriching and extending the learning of students through PBL projects. The goal is to promote not only collaborative skills and student ownership of learning but also to promote student success in state and national standards.
