Secure Electronic Lock Using Pic 16f628a Microcontroller
Source: Cornell University
The proposed system implements an electronic embedded lock that provides a great benefit over a traditional lock, which uses only a manual key. If in case, the key is lost or stolen then anyone can open the lock using the key. On the other hand, losing a long and complex password or getting it stolen is harder as compared to a traditional key. Further, a combination of both, the manual key with a computerized password makes the system more secure. A longer password will reduce the possibilities of getting the code broken and opening the lock. The authors' system comprises of a keypad and HD44780 20x2 LCD along with a PIC16f628a microcontroller.
