EASE 1

Question 1

What is the primary purpose of a breadboard?

Answer 1

To create temporary electrical circuit connections

Question 2

Source Code is composed in?

Answer 2

Arduino IDE

Question 3

Which pin has a built-in LED?

Answer 3

Pin 13

Question 4

What are parallel circuits?

Answer 4

A parallel circuit is a circuit that contains multiple pathways, or branches

Question 5

What are Schematics?

Answer 5

Symbolic descriptions of a circuit’s connections

Question 6

What is the easiest way to tell a resistor’s level of resistance?

Answer 6

Look at the colour stripes and calculate the resistance

Question 7

What is a series circuit?

Answer 7

In-line circuitry

Question 8

What is a good analogy for current?

Answer 8

Water-and-pipe analogy - if we have a water pump that exerts pressure (voltage) to push water around a “circuit” (current) through a restriction (resistance), we can model how the three variables interrelate.

Question 9

What is the mathematical formula for OHM’s law?

Answer 9

IVR triangle. I = current; V = voltage; R = resistance

Question 10

What is a good analogy for voltage?

Answer 10

Refer to the water-and-pipe analogy. In this analogy, voltage is represented by the water pressure

Question 11

What is the definition of a circuit?

Answer 11

A circuit is a complete circular path that electricity flows through

Question 12

LED positive and negative

Answer 12

Long side = anode = positive; Short side = cathode = negative

Question 13

What is the symbol for LDR?

Answer 13

A wiggly line or box within a circle with two lines pointing at it

Question 14

What is the symbol for a resistor?

Answer 14

Wiggly line or a box

Question 15

What is the difference between schematics and writing diagram?

Answer 15

A schematic shows the plan and function for an electrical circuit, but is not concerned with the physical layout of the wires whilst a writing diagram show how the wires are connected and where they should located in the actual device and the connections between parts

Question 16

What is a function call that makes digital output?

Answer 16

digitalWrite()

Question 17

The Arduino board, that can be produced as output component

Answer 17

The Arduino board can only make a digital output. If there are no additional external output components, the Arduino can utilise the onboard LED on pin 13

Question 18

Example of output command listed in digital write ()

Answer 18

(pinNum, MODE)

Question 19

What would you do if you received a syntax error while verifying code?

Answer 19

Check your code for errors

Question 20

Why wouldn’t a project behave like you expect it to?

Answer 20

You most probably have a bug

Question 21

What happens if you leave out a semicolon?

Answer 21

Syntax error

Question 22

Instruction to set a pin up for input

Answer 22

pinMode(pinNum, INPUT);

Question 23

Source code will make the program wait for one second

Answer 23

delay(1000)

Question 24

Void setup() {} is known as …

Answer 24

The setup function

Question 25

What are comments?

Answer 25

Comments are notes left by the developer that cannot be read by the computer. They are created using // and these insinuate that the computer is not able to read the comment

Question 26

What is the language used in the Arduino program?

Answer 26

C

Question 27

What should you do after make a change to some code/

Answer 27

Upload it onto the board

Question 28

Commands turns voltage on

Answer 28

digitalWrite (pinNum, HIGH);

Question 29

Lines start with // or are between /* and */

Answer 29

Are comments and are ignored by the comupter

Question 30

How many setup functions can you have in one program?

Answer 30

One

Question 31

An example of a pair of delimiters

Answer 31

{ } - braces, for functions and other constructs
“ “ - quotes, for strings
‘ ‘ - single quotes, for characters
[ ] - (square) brackets, in arrays
< > - angle brackets
( ) - parentheses, for function argument lists and other things
/* */ - multi-line comments

Question 32

What is a sequence?

Answer 32

Lines of code executed in that order. Sequence is the order in which the statements are executed

Question 33

If function example

Answer 33

if (this ) {
Do that
}

Question 34

the right way to assign a value to a variable

Answer 34

int Variable name = desired variable value
