DESIGN AND CONSTRUCTION OF AN ELECTRONIC SECURITY KEYPAD LOCK

Abstract

The electronic Security Keypad Lock Project is a basic access control system that is interfaced to a reversible electronic door motor for opening and closing the door. The "Code Lock" ability will allow the rightful user to deploy the platform to any property that requires simple password-protection. The Intel microcontroller used ensures low costs. The project Exploits the versatility of the microcontroller and flexibility of implementation of security using software including features which prevent criminals from breaking the password protection such features include password encryption, security keypad lockout after three fail attempts, and wire tapping lockout. Combining these feature makes for more protection; reliable, efficient and effective lock whose limitations are minimal. iv
