micro quiz 1 p3

Question 1

is an open-source electronics platform based on easy-to-use hardware and software

Answer 1

Arduino

Question 2

Arduino boards are relatively inexpensive compared to other microcontroller
platforms

Answer 2

Inexpensive

Question 3

The Arduino Software (IDE) runs on Windows, Macintosh OSX, and Linux
operating systems. Most microcontroller systems are limited to Windows.

Answer 3

Cross-platform

Question 4

The Arduino Software (IDE) is easy-to-use for
beginners, yet flexible enough for advanced users to take advantage of as well. For teachers,
it’s conveniently based on the Processing programming environment, so students learning to
program in that environment will be familiar with how the Arduino IDE works.

Answer 4

Simple, clear programming environment

Question 5

The Arduino software is published as open source
tools, available for extension by experienced programmers. The language can be expanded
through C++ libraries, and people wanting to understand the technical details can make the
leap from Arduino to the AVR C programming language on which it’s based. Similarly, you can
add AVR-C code directly into your Arduino programs if you want to.

Answer 5

Open source and extensible software

Question 6

The plans of the Arduino boards are published
under a Creative Commons license, so experienced circuit designers can make their own
version of the module, extending it and improving it. Even relatively inexperienced users can
build the breadboard version of the module in order to understand how it works and save
money

Answer 6

Open source and extensible hardware

Question 7

You can control your board functions by sending a ____________ to the microcontroller on
the board via Arduino IDE (referred to as uploading software).

Answer 7

set of instructions

Question 8

Arduino IDE

Answer 8

Step 1: First you must have your Arduino board (you can choose your favorite board) and a USB
cable. In case you use Arduino UNO, Arduino Duemilanove, Nano, Arduino Mega 2560, or Diecimila, you
will need a standard USB cable (A plug to B plug), the kind you would connect to a USB printer as shown
in the following image.
Step 2: Download Arduino IDE Software
Step 3: Power up your board.
Step 4: Launch Arduino IDE
Step 5: Open your first project
Step 6: Select your Arduino board.
Step 7: Select your serial port

Question 16

Use it to initialize the variables, pin modes,
start using libraries, etc. The setup function will only run once, after each power up or reset of the Arduino
board

Answer 16

The setup() function

Question 17

does precisely what its name suggests, and loops consecutively, allowing your program to change and
respond. Use it to actively control the Arduino board

Answer 17

the loop() function

Question 18

Data Types

Answer 18

void, Boolean, char, unsigned char, byte, int, unsigned int, word, long, unsigned long, short, float, double, array, String-char array, string-object

Question 19

The void keyword is used only in function declarations. It indicates that the function is expected
to return no information to the function from which it was called

Answer 19

Void

Question 20

A Boolean holds one of two values, true or false. Each Boolean variable occupies one byte of
memory.

Answer 20

Boolean

Question 21

A data type that takes up one byte of memory that stores a character value. Character literals are
written in single quotes like this: ‘A’ and for multiple characters, strings use double quotes: “ABC”.

Answer 21

Char

Question 22

Unsigned char is an unsigned data type that occupies one byte of memory. The unsigned char
data type encodes numbers from 0 to 255.

Answer 22

Unsigned char

Question 23

A byte stores an 8-bit unsigned number, from 0 to 255.

Answer 23

Byte

Question 24

Integers are the primary data-type for number storage. int stores a 16-bit (2-byte) value. This
yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1).

Answer 24

Int

Question 25

Unsigned ints (unsigned integers) are the same as int in the way that they store a 2 byte value. Instead of storing negative numbers, however, they only store positive values, yielding a useful range of 0 to 65,535 (2^16) - 1). The Due stores a 4 byte (32-bit) value, ranging from 0 to 4,294,967,295 (2^32 - 1).

Answer 25

Unsigned int

Question 26

On the Uno and other ATMEGA based boards, a word stores a 16-bit unsigned number. On the Due and Zero, it stores a 32-bit unsigned number.

Answer 26

Word

Question 27

Long variables are extended size variables for number storage, and store 32 bits (4 bytes), from 2,147,483,648 to 2,147,483,647.

Answer 27

Long

Question 28

Unsigned long variables are extended size variables for number storage and store 32 bits (4 bytes). Unlike standard longs, unsigned longs will not store negative numbers, making their range from 0 to 4,294,967,295 (2^32 - 1).

Answer 28

Unsigned Long

Question 29

A short is a 16-bit data-type. On all Arduinos (ATMega and ARM based), a short stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1).

Answer 29

Short

Question 30

Data type for floating-point number is a number that has a decimal point. Floating-point numbers are often used to approximate the analog and continuous values because they have greater resolution than integers.

Answer 30

Float

Question 31

On the Uno and other ATMEGA based boards, Double precision floating-point number occupies four bytes. That is, the double implementation is exactly the same as the float, with no gain in precision. On the Arduino Due, doubles have 8-byte (64 bit) precision.

Answer 31

Double

Question 32

Variables and Constant

Answer 32

local variables formal parameters. global variables

Question 33

Variables that are declared inside a function or block are local variables. They can be used only by the statements that are inside that function or block of code. Local variables are not known to function outside their own.

Answer 33

Local Variables

Question 34

Global variables are defined outside of all the functions, usually at the top of the program. The global variables will hold their value throughout the life-time of your program. A global variable can be accessed by any function. That is, a global variable is available for use throughout your entire program after its declaration.

Answer 34

Global Variables

Question 35

What does void setup() mean?

Answer 35

This is a declaration for a function called "setup". This exact line is required in every Arduino sketch ever. Any code that lives inside setup()'s curly brackets ({ and }) runs once at the very beginning of your program and then never again

Question 36
