Exploring Arduino Fundamentals

What is the primary function of an Arduino board?

• To replace traditional computers in all applications.

• To act as a power supply for devices.

• To serve as a microcontroller platform for building electronic projects.

• To serve as a simple calculator for basic math operations.

Which programming language is primarily used for Arduino programming?

• JavaScript

• C/C++

• Java

• Python

What is the purpose of the Arduino IDE?

• To create 3D models for printing.

• To design websites and applications.

• The purpose of the Arduino IDE is to facilitate the development and uploading of code to Arduino hardware.

• To manage databases and server configurations.

Name one common type of sensor that can be used with Arduino.

• DHT11 humidity sensor

• MQ-2 gas sensor

• HC-SR04 ultrasonic sensor

• LM35 temperature sensor

What does PWM stand for in the context of Arduino?

• Pulse Width Measurement

• Pulse Wave Modulation

• Power Width Modulation

• Pulse Width Modulation

How do you upload a sketch to an Arduino board?

• Connect the Arduino to your computer, select the board and port in the Arduino IDE, and click 'Upload'.

• Connect the Arduino to your phone and use the mobile app to upload.

• Select the board in the Arduino IDE and click 'Download'.

• Upload the sketch via Bluetooth without connecting the Arduino to a computer.

What is a breadboard used for in Arduino projects?

• A breadboard is used for storing Arduino code.

• A breadboard is used for creating 3D models of circuits.

• A breadboard is used for powering Arduino boards only.

• A breadboard is used for prototyping and testing circuits in Arduino projects.

Explain the difference between digital and analog pins on an Arduino.

• Analog pins only work with digital signals, while digital pins can read voltage levels.

• Digital pins handle binary signals (HIGH/LOW), while analog pins read varying voltage levels.

• Digital pins can read varying voltage levels, while analog pins handle binary signals.

• Both digital and analog pins can only handle binary signals.

What is the function of the 'loop()' function in an Arduino sketch?

• The 'loop()' function runs the main code repeatedly in an Arduino sketch.

• The 'loop()' function stops the execution of the program.

• The 'loop()' function is used to define variables in an Arduino sketch.

• The 'loop()' function initializes the Arduino board.

How can you read the value from a temperature sensor using Arduino?

• Use 'analogRead(pin)' to read the sensor value and convert it to temperature.

• Use 'readTemperature(pin)' to get the temperature value.

• Connect the sensor directly to the power supply without reading.

• Use 'digitalRead(pin)' to read the sensor value.
