and send data to serial monitor using Serial.print()

Question 5

is short for binary digit and is the smallest data unit in a digital system. A bit is either a single 1 or a single 0.

Answer 5

Bit

Question 6

consists of a series of bits. The most common length for a byte “word” is 8 bits.

Answer 6

Byte

Question 12

Looks for the next valid integer in the incoming serial. The function terminates if it times out.

Answer 12

Serial.parseInt()

Question 13

a _____is a data type composed of a number that is not an integer, because it includes a fraction represented in decimal format.

Answer 13

Float

Question 14

_____ are used to store text

Answer 14

Strings

Question 15

To read a string type of data from the serial monitor, you need to use _____ function/command to capture the string type of data.

Answer 15

Serial.readString()

Question 16

The _____ is a component that connects two points in a circuit when you press it. The example turns on an LED when you press the button.

Answer 16

Pushbutton

Question 17

A pushbutton will need a _____ when it is used in conjunction with a microprocessor or microcontroller as an input. The main reason for using it is to ensure a defined state (0 or 1) is present at the microcontroller’s input, otherwise the input could be left floating (which is unwanted).

Answer 17

resistor

Question 18

The ______isused to read the logic state at a pin. It is capable to tell whether the voltage at this pin is high (~ 5V) or low (~ 0V) or, in other words, if the pin is at logic state 1 or 0 (or HIGH/LOW).

Answer 18

digitalRead() function

Question 19

The _____ is the most basic of all programming control structures. It allows you to make something happen or not, depending on whether a given condition is true or not.

Answer 19

if() statement

Question 20

It is a variable qualifier that modifies the behavior of the variable, making a variable “read-only”. This means that the variable can be used just as any other variable of its type, but its value cannot be changed. You will get a compiler error if you try to assign a value to a const variable.

Answer 20

Constant (const)
