Microcontroller Basis

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

Is there a microcontroller inside of me? (Printer)

• 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

An input unit is for...

• processing the received signals

• sending out signals

• collecting signals and needed data e.g temperature sensor

A control unit is for...

• processing the received signals

• sending out signals

• collecting signals and needed data e.g temperature sensor

An output unit is for...

• processing the received signals

• sending out signals

• collecting signals and needed data e.g temperature sensor

Microcontrollers can program themselves.

• True

• False

Microcontrollers “listen” to sensors and “talk” to actuators. They decide what to do based on a set of instructions (program) that you write.

• True

• False
