What is the purpose of a sensor in an Arduino project?

• To detect and measure physical properties for interaction with the environment.

• To display information on a screen.

• To store data for future use.

• To power the Arduino board.

How do you connect a temperature sensor to an Arduino?

• Connect VCC to 3.3V, GND to 5V, and signal to an analog pin.

• Connect VCC to 5V, GND to GND, and signal to an analog pin (e.g., A0).

• Connect VCC to GND, GND to 5V, and signal to digital pin.

• Connect VCC to 5V, GND to analog pin, and signal to GND.

What is the function of a stepper motor in robotics?

• To generate random movements in robotics.

• To store energy for robotic operations.

• To increase the speed of robotic components.

• To provide precise control of movement and positioning in robotics.

Describe the basic wiring for a stepper motor with an Arduino.

• Connect stepper motor to driver, driver to Arduino pins, and power appropriately.

• Power the motor with a standard 9V battery without a driver.

• Use only one wire to connect the motor to the Arduino.

• Connect stepper motor directly to Arduino without a driver.

How do you control the position of a servo motor using Arduino?

• Write a program in Python to control the servo motor.

• Use the Servo library to control the position of a servo motor by writing angles to it.

• Connect the servo directly to the power supply without using Arduino.

• Use a potentiometer to control the servo position manually.

What is the difference between a continuous and a standard servo motor?

• Continuous servos are used only in robotics, while standard servos are used in all applications.

• The main difference is that continuous servos allow for full rotation, while standard servos have a limited range of motion.

• Continuous servos are more powerful than standard servos.

• Standard servos can rotate continuously while continuous servos cannot.

What is a relay module and how is it used with Arduino?

• A relay module is used with Arduino to control high-power devices using low-power signals.

• A relay module is used to connect multiple Arduinos together.

• A relay module is a type of sensor for measuring temperature.

• A relay module is used to increase the power of Arduino signals.

Explain how to control a high voltage device using a relay module.

• Control the device using a smartphone app without any hardware.

• Use a relay module to switch the high voltage device on and off safely.

• Connect the high voltage device directly to the power source.

• Use a fuse instead of a relay module for control.

What programming language is primarily used for Arduino development?

• Java

• Python

• JavaScript

• C/C++

What is the purpose of the setup() and loop() functions in Arduino programming?

• The setup() function initializes settings, and the loop() function runs the main code continuously.

• The setup() function is optional, and the loop() function only runs once.

• The setup() function is used for debugging, and the loop() function handles user input.

• The setup() function runs the main code, and the loop() function initializes settings.
