This document presents an access control system project that uses a microcontroller and keypad to authenticate users through a password. It includes a block diagram showing the keypad, microcontroller, load driver, and alarm components. The circuit diagram shows how these components connect to the microcontroller and LCD display. It then describes the working of the system, including displaying a login prompt, entering a password via keypad, verifying the password, and triggering an alarm or unlocking a door based on the result.
