What is an example of the variable type - "int "?

• 327678

• "32,768"

• 32,768.1

• -32768

Answer explanation

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767

What is an example of the variable type - "char"?

• 'A'

• ABC

• "ABC"

• "A"

Answer explanation

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767

• 12345.6

• 123456

• 12345.67

• 1.23456

Answer explanation

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767

What is an example of the variable type - "bool"?

• false

• true

• 12345.67

• ABC

Answer explanation

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767
