Ladder Logic programming has been expanded to include functions such as Counters, Timers, shift Registers and math operations. Ladder logic is a method of drawing electrical logic schematics. It is now a graphical language very popular for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them.

ENCRYPTION KEY GENERATION FOR DIGITAL CIRCUITS USING ANALOG CIRCUITSIRJET Journal
This document proposes a novel method for generating encryption keys for digital systems using an analog circuit approach. The method uses Chua's circuit combined with a noise generator to produce random oscillations. These analog signals are converted to digital using an ADC and stored as an 8-bit binary key on an SD card. Simulations show the output key changes randomly after each interval, making it difficult to duplicate without the original circuit components. This hybrid analog-digital approach could generate secure encryption keys that are nearly impossible to reverse engineer.

Introduction to the Project
This senior design project is carried out for our sponsor company Vacant Property
Security, LLC (VPS) which was founded in 1993. VPS is a trusted leader in securing,
maintaining, and managing vacant properties across a wide range of residential and commercial
sectors. They have locations in Los Angeles, CA, Atlanta, GA, Miami, FL, Chicago, IL, Detroit,
MI, Cleveland, OH, Philadelphia, PA, Newark, NJ, and Dallas, TX. VPS allows customers to
protect their vacant properties against unauthorized access and property decay.
The company’s main goal is to ensure that properties retain their value and provide
customers peace of mind in knowing that their vacant properties are safe and secure. VPS used to
order security doors from a company in UK, which recently stopped manufacturing them. Hence,
our objective was to solve their problem by building a replacement door. The intended purpose
of this project is to build a digital combination lock system that will allow to unlock the door
which will be built by the Mechanical Engineering senior design team for VPS. The door is
made of steel and it features a keypad where codes can be entered to gain access to the property
while providing additional security from intruders. The focus of our Electrical Engineering
Design team was to design and rebuild a door lock system, where we can enter codes that will
interact with the main controller which in turn will interact with the locking mechanism and
allow us to unlock the door. Finally, this digital combination control lock system is mounted on
the door built by the Mechanical Engineering Design team.
Moreover, this electronic lock system works based on combination codes and has a
buzzer attached to it which will further facilitate the customers. These doors are expected to
provide security in the building.
Our Electrical Engineering project team consists of Dinuka Kuruppu, Ruzova Dahal, and
Shakya Jayakody. We were supported by our advisor Dr. Davis Harbour and Dr.Paul Hummel of
Louisiana Tech University in Ruston, Louisiana and also by Mr. Chad Mosley of Vacant
Property Security, LLC in Dallas, Texas. Besides, we planned and worked in collaboration with
the Mechanical Engineering Team throughout the year to successfully complete the project.

Requirements
We were required to design and built five button color coded keypad to enter the password.
However, to be able to reset the password without creating conflict of command, we decided to
add a master button.
Process
To add six buttons, we decided to do the PCB design to make the schematic and layout for the
keypad. We used CADSoft Eagle PCB Design Software to do the PCB layout for the keypad.
The schematic was based on 2 by 3 matrix layout design as seen in figure.. We ordered the push
buttons from Digi key and based on the measurements from the data sheet, the schematic was
made using the software. Next, the layout was made using the same software as seen in figure…
Figure: 2 by 3 matrix design Figure: PCB Layout
After making the layout, it was printed on a photo paper using laser printer. By applying heat for
30 minutes, the mirror image of the layout was printed on the copper clad board. The board was
then dissolved into Ferric Chloride solution for 30-40 minutes to fabricate the copper board.

Finally, the PCB layout was ready. Holed were drilled using hand drills. The push buttons were
inserted and were soldered from behind the board. Two wires from the rows and three wires
from the columns of 2 by 3 matrix buttons were soldered and connected to the main controller.
The keypad was then programmed by coding on the Atmel Studio 7.
The process can be seen in pictures below:
