Abstract:
In an era marked by escalating security concerns, safeguarding possessions has
emerged as a paramount priority, necessitating continual technological innovation.
However, as security technologies advance, so too do the strategies employed by
perpetrators. In response to this evolving landscape, this paper presents a novel approach
centered around the utilization of the PIC16F877A microcontroller to fortify locker
security systems. The proposed system operates by juxtaposing an input passcode against
a pre-stored reference within the microcontroller's memory. Upon successful
authentication, the locker mechanism is disengaged, permitting access. Conversely, failed
attempts trigger an LCD display prompt signaling a "RETRY" message. Subsequent
erroneous entries activate an integrated electric shock mechanism coupled with an
audible alarm, serving as a potent deterrent against unauthorized access. Despite the
strides made in technological advancement, theft remains an enduring threat, particularly
in the realm of locker security. To mitigate this risk, our system embodies a multifaceted
security architecture, harnessing the computational capabilities of the PIC16F877A
microcontroller to fortify locker enclosures. By embracing these innovative features, our
solution endeavors to establish a formidable barrier against unauthorized entry, thereby
enhancing the overall security landscape and safeguarding personal belongings with
heightened efficacy and resilience.
