This project proposes a basic password validation security system based on ESP32. It receives the password as input from the user from the keyboard module and validates it against the database entries. If the user is allowed, the green LED will turn on and the buzzer will make a sound indicating the access is permitted. If the access is not permitted, the red LED will turn on and the buzzer will make a distinctive sound.

Every attempt is logged into the database and is accessible to the admin user via the webserver. The admin can also blacklist/whitelist users in the webserver and the changes will be immediately picked up by the controller. The admin can also export all the attempts in a CSV format for further analysis.

For the implementation of this project, the following hardware components were used:

• ESP-WROOM-32
• 2 x LED (one red, one green)
• 1 x Passive buzzer
• 1 x Breadboard
• 1 x Keyboard module
• Wires
