Understanding Arduino and Servo Control

What is the primary function of a microservo motor?

• To generate linear motion

• The primary function of a microservo motor is to control angular position.

• To increase rotational speed

• To provide power supply

Which component is used to control the direction of the servo in this project?

• Voltage regulator

• PWM signal

• Resistor

• Microcontroller

What is the role of the Arduino board in this project?

• The Arduino board functions as a storage device for project data.

• The Arduino board serves as a display interface for user input.

• The Arduino board is used as a power supply for the project.

• The Arduino board acts as the microcontroller that controls the project components.

In Tinkercad, how do you connect a push-button to a digital pin on the Arduino?

• Connect both terminals of the push-button to 5V directly.

• Connect one terminal to a digital pin and the other to another digital pin.

• Connect the push-button in series with the Arduino power supply.

• Connect one terminal of the push-button to a digital pin and the other terminal to ground, with a pull-up resistor to 5V.

What is the correct way to connect the microservo to the Arduino?

• Connect the power wire to 5V, ground wire to a digital pin, and control wire to GND.

• Connect the power wire to 5V, ground wire to GND, and control wire to a PWM pin (e.g., pin 9).

• Connect the power wire to 3.3V, ground wire to GND, and control wire to an analog pin (e.g., pin A0).

• Connect the power wire to GND, ground wire to 5V, and control wire to a digital pin (e.g., pin 10).

Which command is used to rotate the servo clockwise in the code?

• servo.write(angle) where angle > current position

• servo.turn(angle)

• servo.move(angle)

• servo.rotate(angle)

What is the purpose of using conditional statements in the Arduino code?

• To enable decision-making and control flow based on specific conditions.

• To simplify the code structure without any conditions.

• To increase the execution speed of the program.

• To eliminate the need for loops in the code.

If the servo is not moving, what is the first thing you should check?

• Power supply

• Servo motor type

• Control signal frequency

• Wiring connections

What safety precautions should you take when working with physical Arduino components?

• Always power off before connecting components, use resistors, avoid static discharge, and work in a ventilated area.

• Use only bare wires without resistors

• Work in a humid environment

• Connect components while powered on

Analyze the following code snippet: What will happen if button1 is pressed? (Code: if(digitalRead(button1) == HIGH) { servo.write(180); })

• The servo will move to 90 degrees.

• The button will have no effect on the servo.

• The servo will turn off completely.

• The servo will move to 180 degrees.
