What are Embedded
Systems?
Embedded systems are specialized
computing systems that perform
dedicated functions or tasks within
larger systems. They combine hardware
and software to achieve specific control
functions.

4. Ubiquitous: Found in everyday devices.
Efficiency: Automates tasks and optimizes processes.
Real-Time Performance: Critical for safety and
monitoring.
Cost-Effective: Cheaper than general-purpose computers.
Energy Efficient: Low power consumption.
Innovation Driver: Key to IoT and smart technology.
Reliable: Long-term operation in critical applications.

Embedded Systems

5. What is a
Microcontroller?
A microcontroller is a small, low-cost
computer on a single integrated
circuit, designed to control specific
electronic devices and systems. It's
the "brain" behind many everyday
devices like remote controls,
washing machines, and automotive
systems.

7. Common types of microcontrollers
include 8-bit (e.g., 8051, AVR
Atmega328P), 16-bit (e.g., PIC,
MSP430), and 32-bit (e.g., ARM Cortex-
M). Each type offers varying levels of
performance, memory capacity, and
features, suitable for a wide range of
applications.

8. Introduction to Arduino
Arduino is an open-source platform
used for building electronics projects.
Arduino consists of both a physical
programmable circuit board (often
referred to as a microcontroller) and a
piece of software, or IDE (Integrated
Development Environment) that runs on
your computer, used to write and
upload computer code to the physical
board.
