2. WHAT WE LEARN
• Embedded Systems.
• Microcontroller.
• Microprocessor vs. Microcontroller.
• Arduino.
• Digital vs Analog Signal.
• I/O Arduino Uno pins.
• Arduino IDE.
• Simulations Programs.
4. WHAT IS AN EMBEDDED SYSTEMS?
An embedded system is a microprocessor-based
computer hardware system with software that
is designed to perform a dedicated function,
either as an independent system or as a
part of a large system. At the core is
an integrated circuit designed to carry
out computation for real-time operations.
6. WHAT IS MICROCONTROLLER?
• A microcontroller is an integrated circuit (IC) device used for controlling
other portions of an electronic system, usually via a microprocessor unit
(MPU), memory, and some peripherals.
• The most common way to refer to this category of integrated circuits is
“microcontroller" but the abbreviation “MCU” is used interchangeably as it
stands for “microcontroller unit”. You may also occasionally see “µC”
(where the Greek letter mu replaces “micro”).
10. WHAT IS ARDUINO?
• Arduino is an open-source electronics platform based on easy-to-use hardware and
software.
• Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a
Twitter message - and turn it into an output - activating a motor, turning on an LED,
publishing something online. You can tell your board what to do by sending a set of
instructions to the microcontroller on the board.
• To do so you use the Arduino programming language (based on Wiring), and the
Arduino Software (IDE), based on Processing.
11. WHY ARDUINO?
• Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms.
• Cross-platform - The Arduino Software (IDE) runs on Windows, Macintosh OSX, and Linux operating
systems.
• Simple, clear programming environment - The Arduino Software (IDE) is easy-to-use for beginners, yet
flexible enough for advanced users to take advantage of as well.
• Open source and extensible software - The Arduino software is published as open source tools, available
for extension by experienced programmers.
• Open source and extensible hardware - The plans of the Arduino boards are published under a Creative
Commons license, so experienced circuit designers can make their own version of the module, extending it
and improving it.
20. WHAT IS SENSORS?
• sensors are devices or machines used to detect the presence of any physical object in
the vicinity and send information about the same to the receiving end.
• Any physical quantity like pressure, force, strain, light etc.
• Basically, this are classified as analog and digital sensors.
• Data is collected from the environment using sensors and used for internet of things.
• Ex: Temperature, Light, Pressure, Ultrasonic, Color, Touch, Flow and Level, Smoke,
Accelerometer, Infrared, Humidity, and Tilt.
22. WHAT IS ACTUATORS?
• An actuator is a device that uses a form of power to convert a control signal into
mechanical motion. From electric door locks in automobiles, to ailerons on aircraft,
actuators are all around us. Industrial plants use actuators to operate valves,
dampers, fluid couplings, and other devices used in industrial process control.
