Keypad Door Lock using AVR Microcontroller – Atmega16

Keypad Door Lock using AVR Microcontroller – Atmega16

Password Based Keypad Door Lock  In this article, a digitally secured lock based on password verification is explained. The system uses a seven segment display array to show the password, a matrix keypad to enter the numbers/password and operates a relay (to activate the solenoid valve) for locking and unlocking purpose. The system alarms through
