This tutorial covers Boolean data types and the Boolean NOT operator. It explains the concept of Boolean values as binary states, either true or false, and how to declare and initialize Boolean variables in the Arduino IDE. The tutorial demonstrates testing Boolean equivalence using an LED and introduces the Boolean NOT operator to switch states, showcasing its practical application in programming.

What is a Boolean data type primarily used to represent?

• A floating-point number

• A sequence of characters

• A binary state of true or false

• A range of numbers

In Boolean logic, which of the following is considered true?

• Negative numbers only

• 0

• Any non-zero integer

• Only the number 1

How do you declare a Boolean variable in the Arduino IDE?

• Using the keyword 'int'

• Using the keyword 'float'

• Using the keyword 'Boolean'

• Using the keyword 'char'

What is the purpose of the Boolean NOT operator?

• To add two Boolean values

• To divide two Boolean values

• To multiply two Boolean values

• To switch a Boolean variable to its opposite state

What symbol is used to represent the Boolean NOT operator?

• &

• |

• !

• ^

What happens to a Boolean variable when the NOT operator is applied?

• It becomes one

• It becomes zero

• It switches to the opposite state

• It remains unchanged

In the context of the tutorial, what practical application was demonstrated using the NOT operator?

• Reading a sensor value

• Sending data over a network

• Blinking an LED

• Controlling a motor
