if-else Structure
These questions are based on the if-else slideshow found here.

Which of the following statements is true about if-blocks:

Starts with if

May have multiple else-ifs (or none)

May finish with an else (or not)

All of these statements are true

Inside of the parentheses of an if statement goes the true or false statement known as the:

Conditional expression

Assignment

Statement

Question

Which of the following does NOT require a conditional expression:

None of these

If

else

else if

Which of these phrases summarises a simple if...else structure:

Only decision trees more complex than these

Do this or do nothing

Do this, that, or both this and that

Do this or do that

When you have an if with no else if and no else clause, which of the following summarizes its behavior:

Do this or do that

Only decision trees more complex than these

Do this, that, or both this and that

Do this or do nothing

Digital Signals
These questions are based on the Digital Inputs slide show found here.

All input to the Arduino comes to it from the outside world in what form:

Analog signal

Digital signal

Buttons

Potentiometer

The Arduino will detect an input signal as digital with which of the following function calls?

inputValue=analogWrite(pin);

inputValue=digitalRead(pin);

inputValue=digitalWrite(pin);

inputValue=analogRead(pin);

Which statement is true about signals and messages

A signal is transmitted through a message

A message is transmitted through a signal

All messages are digital

All signals are digital

Which of the following functions is used for digital output?

Which of the following is a good example of reading digital input from pin 4 and assigning the resulting value to the variable inputValue?

digitalRead(inputValue)=4;

digitalRead(4)=inputValue;

inputValue=digitalRead(4);

4=inputValue(digitalRead);

How do you check to see if the button is being pushed?

if(inputValue==HIGH)

if(inputValue==digitalRead(4))

if(inputValue==PUSHED)

if(inputValue==LOW)

Match the signal value with the voltage level.

FALSE
HIGH
LOW
TRUE
0
1

The loop

Global space

The setup

Write the serial command that creates a new line after printing its requested text. Do not include printable text or the semicolon.
