Quiz Q3 Flashcards
Where do you set the Arduino Board and the Port you are going to use?
Tools
The other term for an Arduino File?
A sketch
3 main parts of Arduino IDE
Editor, Message, Console
the language used by a program
syntax
descriptive statements that the programmer writes to help explain the code
comment
ignored by the compiler, you may write anything you want
comment
with “ // “ symbol
single line comment
/*
this
is
a
comment
*/
multiline comment
this tells the compiler that a chunk of code is finished and are moving on to the next code
semicolon
signifies a complete statement, equivalent to a period in a sentence
; semicolon
what happens when you forgot a semicolon
an error occur
used to enclose further instructions carried out by a function
curly brace { }
pieces of code that are used so often that they are encapsulated in a certain keywords so that you can use them more easily
function
the name of the function will appear
orange
information the function uses when it runs
arguments
how to you write a function?
pinMode ( );
to easily organized the codes, spaces are made
indention
where arduino code type in
editor
how to use functions
- define functions
- call the function
- use the result of the function
Define functions –
enclose the statements of the function
Call the function –
use the function by using its name, adding any parameters if needed
Use the result of the function –
result can be made from the function
provide a way to modularize your code and make it reusable
functions
instead of having a single, very long program, you can break up your code into modules of code with-
functions
pin: the Arduino pin number
value: HIGH or LOW
digitalWrite
how do you write digitalWrite
digitalWrite (pin number, LOW/HIGH)
write a HIGH or LOW value to a digital pin
digitalWrite ()
reads the value from a specified digital pin, either HIGH or LOW
digitalRead ()
pins: the Arduino number you want to read
returns: HIGH or LOW
digitalRead ()
syntax of digitalRead
digitalRead (pin)
pin: the name of the analog input pin to read from (A0-A05, e.g.)
returns: the analog reading on the pin
analogRead ()
data type of analogRead
int (integer)
resolution can be changed (only for Zero, Due and MKR boards) using-
analogReadResolution ()
the input range can be changed using _______ in analogRead
analogReference ()
two required functions in arduino
void setup ()
void loop ()
executes only one time as soon as you upload, power up, or reset Arduino
void setup ()
functions that repeat consecutively until Arduino is turned off
void loop ()
refers to the container of the saved information, not the information itself
variable
a place to store a piece of data, it has a name, a value, and a type
variables
store and recall information
variables
when naming variables:
no spaces
no special characters
no numbers as first character
don’t HIGH/LOW, true/false
functions that stop the tone
noTone ()
you may see it on the start of an Arduino code; a communication to laptop and arduino
serial.begin (9600)
prints strings
serial.print
ex. serial.print (“Hello World”)
allows you to pause the execution of your Arduino program for a specified period
Delay ()
ex. Delay (1000)
measurement in the delay
1000 milliseconds = 1 second
for the pitch and frequency
tone ()
