Question 5

Allows the user to open a saved sketch or any of the stored samples.

Answer 5

open existing sketch

Question 6

This saves the sketch currently in the workspace.

Answer 6

Question 7

When the board is connected, this will display the serial data from the Arduino.

Answer 7

serial monitor

Question 8

When the sketch is saved, the name of the sketch is displayed here.

Answer 8

Question 9

This is the workspace where the sketch code is written.

Answer 9

code area

Question 10

This area displays the status and errors during saving, code compiling, etc.

Answer 10

Question 11

Shows additional information like the details of error messages and size of the compiled program.

Answer 11

text console

Question 12

Indicates what board is being used and which serial port it is connected to.

Answer 12

board and serial port

Question 13

Coding using the Arduino UNO usually has four basic divisions or sections.
namely the Introductory Comments, Declaration Section, Setup Section and Loop Section.

Answer 13

arduino code structure

Question 14

Comments are lines in the program that are used to inform yourself or others about the way the program works.

Answer 14

introductory comments

Question 15

Before variables are used, they have to be declared first. Declaring a variable means defining its type, and optionally, setting an initial value (initializing the variable).

Answer 15

declaration section

Question 16

The setup() function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc.

Answer 16

setup section

Question 17

Is a sequence of instructions that is repeated endlessly

Answer 17

loop section

Question 18

is an attribute or property of data which tells the hardware and the programmer about what kind of data it is. This is done so to add constraints on the data being manipulated such as setting the values that can be stored in it and the operations that can be manipulated.

Answer 18

data type

Question 19

is used to store data, it has name, a value and a type

for example this statement called declaration
int pin = 13;

Answer 19

variable

Question 20

data types can store integer values from -32,768 up to 32,767 and have the syntax int before the variable name.

Answer 20

integer

Question 21

differs from integer types in the range of values available and that it includes decimal values. It can accommodate values from -3.4028235 x 1038 to 3.4028235 x 1038, with 6-7 decimal digits of precision. this data types have the syntax float before the variable name

Answer 21

float

Question 22

this data types that has a simple logical true/false which is a 1 or a 0. The syntax bool before the variable name

Answer 22

boolean

Question 23

this data types can store integer values and a unsigned number from 0 to 255 because it has only 8 bits size. The syntax byte before the variable name.

Answer 23

byte

Question 24

this data types can store a single characters and a signed number from -128 to 127. The syntax char before the variable name.

Answer 24

char

Question 25

this data types are used when texts are needed to be stored and manipulated. Data that can be used in string are alphanumeric and symbols. String data types have the syntax String before the variable name.

Answer 25

string

Question 26

is a form of data type of type integer. Integer data types have numerical values ranging from -32,768 to 32,767.

Answer 26

int

Question 27

is a variable name used to store data. In this case, it is a variable of type Integer and has a value of 13.

Answer 27

ledpin

Question 28

the value stored to ledPin. For this code, it is used to call the address of the LED that will be controlled in this code

Answer 28

13

Question 29

is a single line comment. A comment does not affect how the code will work but is present to help programmers document their codes. In this example, it is used to indicate that the LED is connected to digital pin 13.

Answer 29

LED connected to digital pin 13

Question 30

is one of the two mandatory/default functions used in Arduino. A function is a cluster of code that accomplish a specific task. This function is used to initialize Arduino pins, start using libraries, or do things that are needed to run only once.

Answer 30

void setup ()

Question 31

It indicates that the function does not return a value.

Answer 31

void

Question 32

the name of the function.

Answer 32

setup

Question 33

used to indicates what are the variables used in the function as an input. For the two mandatory/default functions of Arduino, no input variable is needed. Thus, the parentheses are left as is.

Answer 33

( )

Question 34

used to indicate the start of the codes inside the (setup/loop) function.

Answer 34

{

Question 35

is a function that sets the digital pin whether it will be an input(receives data), or an output(sends a signal).

Answer 35

pinMode

Question 36

calls variable ledPin.

Answer 36

ledPin

Question 37

configures ledPin as an output.

Answer 37

output

Question 38

End of the line

Answer 38

;

Question 39

used to indicate the end of the codes inside the (setup/loop)function.

Answer 39

}

Question 40

is another mandatory/default function that, as its name suggests, loops indefinitely. This allows your program to change and respond, depending on what is placed inside the function.

Answer 40

void loop ()

Question 41

is a function that sends a value to the digital pin assigned.

Answer 41

digitalWrite

Question 42

is the variable name assigned to the digital pin

Answer 42

ledpin

Question 43

is the value to be sent to the digital pin. There are two values that can be sent to a digital pin: HIGH (LED turns on), or LOW (LED turns off).

Answer 43

HIGH

Question 44

halts the program for a defined period before a next line of code is executed. In this case, the line “digitalWrite(ledPin, HIGH)” will run for 1000 milliseconds, or 1 second.

Answer 44

delay(1000)
