This document provides an introduction to microcontrollers. It defines a microcontroller as an integrated circuit programmed to perform specific tasks. The key components of a microcontroller are described as the central processing unit, system clock, memory, and peripherals. Examples of where microcontrollers are used include appliances, gadgets, robots, and other electronics. The document outlines the process of programming microcontrollers and provides examples of microcontroller applications like robots and an Arduino project.

3. What is a Microcontroller
A microcontroller is an integrated circuit that is
programmed to do a Specifie task.
Microcontrollers are a really just “ Mini-Computers”
8086

4. The Fundamental components of a
Microcontrollerunit (or Mcu)
• Central Processing unit (or Cpu).
• System clock.
• Memory.
• Peripherals (I/o).

5. Microcontroller are used
● Microcontrollers are hidden in tons of appliances,gadgets,
and other electronics.
● They’re everywhere!

6. Microcontroller programming
1.) Code is written for the microcontroller in an integrated development
environment, a PC program. The code is written in a programming language.
(e.g.C, BASIC or Assembly).
2.) The IDE debugs the code for errors, and then compiles it into binary code which
the microcontroller can execute.
3.) A programmer (a piece of hardware, not a person) is used to transfer the code
from the PC to the microcontroller. The most common type of programmer is an
ICSP (In-circuit serial programmer).

7. Microcontroller applications
●Many robots use
microcontrollers to allow
robots to interact with the
real world.
● Ex. If a proximity sensor
senses an object near by,
the microcontroller will
know to stop its motors
and then find an
unobstructed path.

8. Microcontroller project
Ardunio Microcontroller.
Ultrasonic Range sensors.
Standard servo.
Breadboard.
L293D motor driver.
Plastic gear motors.
Batteries.

9. How can you grt Started
● If you want to develop
for microcontrollers, you
can purchase a
development board which
includes a microcontroller
and all of the necessary
parts to get it working.
(i.e. power supply and a
USB interface)

10. Summary
-A microcontroller is a computer dedicated to a single task.
--Fundamental components to of a microcontroller.
