Word Meaning Picture
Embedded
system
An embedded system is a computer
system with a specific function,
inside a larger mechanical or
electrical system.
Microcontroller A microcontroller fits on a single
chip and contains all units required
to control an external system.
Arduino Arduino is an open-source
electronics platform based on easy-
to-use hardware and software

Input/sensor A device that collects signals from
its environment
Processing A series of actions that produce
events or that lead to a result
Output/actuator A device that sends signals out
based on the input information
after being processed by the
microcontroller
IDE An integrated development
environment which allows you to
edit and upload programs to your
microcontroller
Program A set of instructions that operate
the computer

I/O Module Kit A kit that contains three types of
modules: input modules, output
modules, and the Arduino
controller
Expansion Shield The expansion shield connects the
input and the output modules easily
with the Arduino microcontroller
Flowchart A type of diagram that shows
workflow or process, with the steps
as boxes of various shapes, which
are connected by arrows.
Hardware A physical component that
represents the parts of a computer
system. The hardware is
constructed from electronics circuit
and components
Signal A message passed between devices
to send and receive information
Analog signal An analog signal has an infinite
number of possible values. It
represents an infinite number of
quantities of any type of
information
Digital signal A digital signal has a finite set of
possible values
Read (sensing,
reciving,input)
The Arduino, microcontroller
receives a signal from the input
module/source
analogRead
digitalRead
Write (actuating,
transmitting, output)
The Arduino sends a signal to an
output module/source
analogWrite
digitalWrite
Serial Monitor A useful tool in Arduino to visualize
and monitor the I/O values and
different information

Variables A way of naming and storing a
value for late use by the program
Mapping Shows a value within a certain
range, to one within another range.
Infinite Limitless, endless or impossible to
measure
Analog ambient
light sensor
An analog sensor receives light
intensity ( as an input signal) then
converts it into a voltage signal ( as
an output signal) to be read or used
by another device.
Ambient light Light in the immediate surrounding
Directly
proportional
A relationship between two
quantities where one amount
increases, another amount increases
at the same rate
Inversely
proportional
A relationship between two
quantities where one amount
increases, another amount
decreases at the same rate
Gas valve A device that controls the flow of
gas by changing the size of the
opening area for the gas flow
Analog gas
sensor
An electronic device that indicates a
gas leakage or smoke at a certain
sensitivity level
Fluid A substance, such as a liquid or gas,
that is capable of flowing
