Introduction to Microcontrollers - Lo11 - Unit 5

What is a microcontroller?

• A tiny programmable computer.

• A series of actions/steps that lead to a clear result

• The information or data entered in a system by a user

• The information or data produced by a system based on the input information

Microcontrollers are "embedded" inside some other device so that they can control the features or actions of the product.

• True

• False

Is there a microcontroller inside of me? (AC Unit)

• YES!

• No

A microcontroller has 4 main parts, make sure to select ALL FOUR!!

• Central Processing Unit (CPU)

• Screen

• Random Access Memory (RAM)

• Read Only Memory (ROM)

• Input/Output ports

Identify this component

• Uno Cards

• Raspberry Pi

• Microbit

• Arduino Uno board

A microcontroller at-least should consist of:

• RAM, ROM, I/O ports and timers

• CPU, RAM, I/O ports and timers

• CPU, RAM, ROM, I/O ports and timers

• CPU, ROM, I/O ports and timers

Unlike microprocessors, microcontrollers make use of batteries because they have:

• high power dissipation

• low power consumption

• low voltage consumption

• low current consumption

Why microcontrollers are not called general purpose computers?

• because they have built in RAM and ROM

• because they are designed to perform one dedicated task

• because they are cheap

• because they consume low power

What does the term LED stand for?

• Light Earth Diode

• Light Electrical Duo

• Light Emitting Diode

Motion, light or sound are all examples of possible _____________ by a microcontroller

• input

• output

• pensor

• storage
