Access control vol.2

The project presents a functional access control system based on the Arduino Uno microcontroller. The system utilizes a keypad for password entry, an LCD screen for user communication, and a servo motor along with LED indicators for visual and mechanical access confirmation.

After the password is entered, the system verifies its validity. If the entry is correct, the servo motor activates (simulating a door opening) and a green LED lights up, signaling that access has been granted. If the password is incorrect, a red LED lights up and an appropriate error message appears on the screen.

The project aims to demonstrate the fundamental operating principles of embedded systems, including data input, logic processing, control of output components, and user interaction. It has potential applications in simple security systems, such as electronic locks or access restriction systems.
