Conditional Structures in Arduino

Multiple Choice

Which of the following is not true about a condition in Programming?

• It's either true or false

• usually made up by relational operator, but not all the time

• the state of something with regard to its appearance, quality, or working order.

• We use it in places such as if, for, and while, these control statements will only run when the condition is true

Multiple Choice

Which statement best describes an if condition?

• It repeats actions forever

• It stores values in memory

• It checks if something is true before doing an action

• It sends data to the cloud

Multiple Choice

What will this code do?

• The LED turns off when the button is pressed

• The LED blinks continuously

• The LED turns on when the button is pressed

• Nothing happens

Type the correct syntax for an if statement that checks if a sensorValue is greater than 100.

Multiple Choice

• TRUE

• FALSE

Multiple Choice

You want your Arduino to display “Too Hot” when the temperature is above 30°C and “Normal” otherwise. Which is correct?

• if (temp >= 30)

  {

  Serial.println("Too Hot");

  }

  else {

  Serial.println("Normal"); }

• if (temp > 30) {

  Serial.println("Too Hot"); }

  else {

  Serial.println("Normal"); }

• else (temp < 30) { Serial.println("Normal"); }

• if (temp == 30) {

  Serial.println("Normal"); }

In real life, we often face situations where we must decide based on conditions — just like in if-else coding. Can you share a moment where you had to make a fair or right decision based on a condition?
