This document describes a shopping card system that is intended to facilitate the shopping process. The system uses hardware including a bar code reader, printers, and networked computers. It also uses software like Microsoft Visual Studio, Eclipse, and Excel. Customers receive an ID card upon arrival and present it at shops to record purchases and then at checkout where the total is generated. The system aims to make shopping and billing more efficient with features like purchase tracking and payment options.
The Arduino family of boards use processors developed by the Atmel Corporation of San Jose, California. Most of the Arduino designs utilize the 8-bit AVR series of microcontrollers, with the Due being the primary exception with its ARM Cortex-M3 32-bit processor.

||||The compilation and execution process of C can be divided into multiple steps:|||
Preprocessing - Using a Preprocessor program to convert C source code in expanded source code. "#includes" and "#defines" statements will be processed and replaced actually source codes in this step.
Compilation - Using a Compiler program to convert C expanded source to assembly source code.
Assembly - Using a Assembler program to convert assembly source code to object code.
Linking - Using a Linker program to convert object code to executable code. Multiple units of object codes are linked to together in this step.
Loading - Using a Loader program to load the executable code into CPU for execution.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

5. In this system we have introduced a
Shopping Card for the Customers that will
facilitate them while shopping.
This new system will help in making the
buying and selling process more effective
and accurate.
INTRODUCTION
6. Every Customer upon his arrival in the Mall will
receive a shopping Card that will contain a ID
Number.
The Customer after buying an item from a particular
shop will give his Shopping Card to the Seller.
The Seller would then track the price of the item
through a bar-code reader and update it in the
System on the ID i.e. allotted to the customer.
Method of Usage
7. Method of Usage
After completing his shopping, the customer can later
proceed to the main counter where he would pass the
Shopping Card to the Cashier.
The cashier, after entering the ID in the
system/software developed, will get a list of the
items bought and their prices and would make the
total bill.
The Customer has the option to either pay the bill in
Cash or through a Credit Card.

11. Types of Memory Used
There are three types of Memory:
a) CODE MOMERY
Code memory is the memory that holds the actual
programs that is to be run. This memory is limited to 64Kb. Code
memory may be found on-chip or off-chip.
b) FLASH MEMORY
Flash memory (sometimes called "flash hard disk") is a type of
constantly-powered non volatile that can be erased and
reprogrammed in units of memory called blocks.
Types of Memory Used
12. C) INTERNAL RAM
The program have a bank of 128 bytes of
internal RAM. The internal RAM is found on-
chip.
It is the fastest Ram available.
CONT..
13. FLASH
Low-cost, high-density, high-speed architecture; low power; high reliability
ROM
Read-Only Memory
High-density, reliable, low cost; time-consuming mask required, suitable
for high production with stable code
SRAM
Static Random-Access Memory
Highest speed, high-power, low-density memory; limited density drives up
cost
EPROM
Electrically Programmable Read-Only Memory
High-density memory; must be exposed to ultraviolet light for erasure
Features of Memory
14. Hardware Explanation
A controller consists :
o Powerful CPU tightly coupled with memory
o Various I/O interfaces such as serial port
o If a system is developed with a microprocessor, the designer
has to go for external memory such as RAM, ROM, EPROM
and peripherals.
o But controller is provided all these facilities on a single chip.
o Parallel port timer or counter
o Digital to Analog converter, integrated on to a single silicon
chip.
FURTHER HARDWARE
15. The software used include:
1. Microsoft Visual Studio.
2. Eclipse.
3. Microsoft Excel.
SOFTWARE
16. Function of Software
o Arithmetic Instructions:
These instructions perform several basic operations
(addition, subtraction, division, multiplication etc.) After
execution, the result is stored in the first operand. For example:
o Data Transfer Instructions:
These instructions move the content of one register to
another one. The register which content is moved remains
unchanged.
FUNCTION OF SOFTWARE
17. How this Software works?
All Employs will have a unique ID and password
which they get by registering to software when
they you first time.
Without ID no one can use this software.
There are 2 different things in this software.
1. Administration’s Account.
2. Non-Administration’s Account.
Both account have different features.
Functionality
18. TIMERS
o On-chip timing/counting facility has proved
the capabilities of the microcontroller for
