Arduino Basics

What is the primary software used for programming Arduino boards?

• Arduino IDE

• Raspberry Pi OS

• Microsoft Word

• Python

Name one common component found on an Arduino board.

• resistor

• capacitor

• LED

• microcontroller

What is the function of a digital input pin on an Arduino board?

• To measure temperature

• To control the brightness of an LED

• To read digital signals from external sensors or devices

• To play music

Explain the difference between analog and digital output on an Arduino board.

• Analog output is binary, digital output is continuous.

• Analog output is used for input, digital output for output.

• Analog output is continuous, digital output is discrete.

• Analog output is faster than digital output.

How can you implement a simple LED blinking project using Arduino?

• Connect an LED to pin 13, write a sketch to blink the LED, and upload it to the Arduino board.

• Connect an LED to pin 13, write a sketch to keep the LED constantly on, and upload it to the Arduino board.

• Use a resistor instead of an LED, write a sketch to blink the resistor, and upload it to the Arduino board.

• Connect an LED to pin 5, write a sketch to blink the LED, and upload it to the Arduino board.

What is the purpose of the setup() function in Arduino programming?

• To set the baud rate for serial communication

• To define the loop() function

• To initialize variables, pin modes, libraries, and other settings before the main code execution begins.

• To print debug messages

Describe the role of a resistor in an Arduino circuit.

• A resistor in an Arduino circuit generates heat but serves no purpose.

• A resistor in an Arduino circuit has no impact on other components.

• A resistor in an Arduino circuit limits current flow, protects components, and helps set voltage levels.

• A resistor in an Arduino circuit amplifies current flow.

How can you read data from a sensor using an Arduino board?

• Shake the sensor, wait for data to magically appear, dance around the Arduino board

• Connect sensor, write code, upload to Arduino, monitor data

What is the purpose of the loop() function in Arduino programming?

• The loop() function is used to declare functions

• The purpose of the loop() function is to continuously execute a block of code.

• The loop() function is used to define variables

• The loop() function is responsible for setting up the board

Give an example of an Arduino project that involves both input and output components.

• Watering system with a soil moisture sensor as input and a servo motor as output.

• Light control system with a light sensor as input and a speaker as output.

• Temperature monitoring system with a temperature sensor as input and an LCD screen as output.

• Motion detection system with a PIR sensor as input and a buzzer as output.
