Design and Implementation of Microcontroller-Based R-F Remote Controlled safe with Digital Code Lock and Indicator

摘要

The paper work presents a brief history and evolution of key locks, as well as the various key types and key locks. Also, the basic concepts of telecommunications and modern digital systems are elucidated. The system architecture of a microcontroller-based radio frequency remote controlled lock and indicator is showcased with the attendant description of the operational details. The paper further describes the system implementation. Finally, tests were performed in stages and the results obtained were then used to conclude that an elegant Microcontroller-Based Code Lock System has been achieved.
