ARDUINO PROGRAMMING EXAM QUESTIONS AND VERIFIED ANSWERS

What is the Arduino IDE's native language? - ANSWER C++

What is an object in object-oriented programming? - ANSWER A
construct that combines functional code with a state

Functional Code - ANSWER Code that does things such as
calculations

States - ANSWER Parts of an object that stores something in memory

What are the three main parts of the Arduino programming language? -
ANSWER functions, values, structure

What are values? - ANSWER variables & constants

digitalRead(pin) - ANSWER Reads the value from a specified digital
pin, either HIGH or LOW

digitalWrite(pin, value) - ANSWER Writes HIGH/LOW value to a digital
pine

Value = HIGH/LOW

pinMode(pin, mode) - ANSWER Configures the pin to behave as either
an input/output

pinMode(pin, mode); what are the three modes? - ANSWER INPUT,
OUTPUT, INPUT_PULLUP

analogRead(pin) - ANSWER Reads the value from an analog pin

Which pins are the analog on the arduino UNO? - ANSWER Those that
range from A0 - A5

, analogReference(type) - ANSWER Configures the reference voltage
used for analog input

Type - which type of reference to use

analogWrite(pin, value) - ANSWER Writes an analog value (PWM
wave) to a pin

random(min, max) - ANSWER generates pseudo-random numbers

delay(ms) - ANSWER pauses the program for the amount of time
specified as parameter

Serial - ANSWER Class used for communication btwn arduino board &
computer/other devices

What are the two main parts of a basic arduino sketch? - ANSWER
void setup() {}

void loop() {}

How does void setup() {} behave? - ANSWER Executes once the
program starts

How does void loop() {} behave? - ANSWER Executes continuously

What is the Serial communication library used for? - ANSWER
Communication btwn arduino board & computer/other devices

Serial.begin(9600); - ANSWER opens the serial port and sets data rate
to 9600 bps

With Serial.begin(), what is the baud rate? - ANSWER bits/second of
communication

Classes - ANSWER Collections of functions
