What is Arduino?

What is the primary function of an Arduino board?

• To store large amounts of data like a hard drive.

• To act as the "brains" of an electronics project, controlling components.

• To convert AC power to DC power for household appliances.

• To provide wireless internet connectivity to devices.

What is the name of the main component at the heart of an Arduino board that acts like a mini-computer?

• Transistor

• Resistor

• Microcontroller

• Capacitor

Which type of pins on an Arduino Uno are capable of generating Pulse Width Modulated (PWM) signals for finer control over components like LED brightness or motor speed?

• Analog Input Pins

• Ground Pins

• Digital I/O Pins with a tilde (~)

• Power Pins

What is the resolution of the Analog-to-Digital Converter (ADC) on the Arduino Uno, allowing it to convert continuous voltages into a specific range of digital values?

• 8-bit (0-255)

• 16-bit (0-65535)

• 10-bit (0-1023)

• 12-bit (0-4095)

What is the name of the software used to write code for Arduino, and what programming language does it primarily use?

• Arduino Studio, Python

• Arduino IDE, a modified version of C++

• Arduino Code Editor, Java

• Arduino Workbench, C#

In an Arduino sketch, what is the primary difference between the setup() function and the loop() function?

• setup() defines variables, while loop() executes mathematical operations.

• setup() contains code that runs once at the start, and loop() contains code that runs repeatedly.

• setup() runs repeatedly, while loop() runs only once at the beginning.

• setup() is for input, and loop() is for output.

Which function is used in Arduino to configure a digital pin as an output, for example, to control an LED?

• digitalWrite()

• pinMode()

• analogRead()

• delay()

What are the common tools used to connect external electronic components to an Arduino board for building circuits?

• Soldering iron and solder

• Multimeter and oscilloscope

• Breadboards and jumper wires

• Screwdriver and pliers
