Exploring Arduino Basics

What is an Arduino?

• A brand of electronic components for home appliances.

• An Arduino is an open-source electronics platform for building digital devices.

• A type of microcontroller used only for gaming.

• A software application for designing websites.

What programming language is primarily used for Arduino?

• C/C++

• JavaScript

• Java

• Python

What is the purpose of the Arduino IDE?

• To design hardware components for Arduino boards.

• To manage network connections for IoT devices.

• To provide a graphical interface for 3D modeling.

• The purpose of the Arduino IDE is to facilitate programming and uploading code to Arduino boards.

Name one common type of Arduino board.

• Arduino Uno

• Arduino Mega

• Arduino Pro Mini

• Arduino Nano 2560

What is a digital pin on an Arduino?

• A digital pin can only read analog signals.

• A digital pin on an Arduino is a pin that can read or write binary signals (HIGH or LOW).

• A digital pin can store multiple values at once.

• A digital pin is used for power supply only.

How do you upload a sketch to an Arduino?

• Connect Arduino to Wi-Fi, open browser, upload sketch online.

• Write sketch on paper, scan it, send via email to Arduino.

• Use a smartphone app to upload sketch directly to Arduino.

• Connect Arduino to computer, open IDE, select board/port, write/open sketch, click 'Upload'.

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

• The 'setup()' method runs the main loop continuously.

• The 'setup()' method is used to read sensor data.

• The 'setup()' method is for defining variables only.

• The 'setup()' method initializes the Arduino environment before the main loop runs.

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

• The 'loop()' method is used to initialize variables only once.

• The 'loop()' method allows the Arduino to execute code continuously after the initial setup.

• The 'loop()' method runs only when the Arduino is powered on.

• The 'loop()' method is for setting up hardware connections.

What type of sensors can be used with Arduino?

• Temperature, humidity, light, motion, ultrasonic, gas, and pressure sensors.

• Optical sensors

• Magnetic sensors

• Sound sensors

What is the significance of the 'void' keyword in Arduino programming?

• The 'void' keyword is used to declare global variables.

• The 'void' keyword indicates a function that returns an integer.

• The 'void' keyword signifies that a function does not return a value.

• The 'void' keyword is a data type for storing strings.
