7 Arduino: Servo Control

What is the primary function of a servo motor in robotics?

• To provide linear motion

• To provide precise angular motion

• To generate electrical power

• To convert AC to DC

Which Arduino library is commonly used for controlling servo motors?

• Wire.h

• Servo.h

• LiquidCrystal.h

• SPI.h

What is the typical range of motion for a standard hobby servo motor?

• 0 to 90 degrees

• 0 to 180 degrees

• 0 to 360 degrees

• 0 to 270 degrees

In the Arduino Servo library, which function is used to attach a servo to a pin?

• .attachPin()

• .connect()

• .attach()

• .bind()

How do you specify the angle to which a servo should move using the Arduino Servo library?

• .setAngle()

• .moveTo()

• .write()

• .rotate()

Which of the following is a correct way to declare a Servo object in Arduino?

• Servo myServo;

• servo myServo;

• Servo: myServo;

• servo: myServo;

When controlling multiple servos, what is a common issue that might arise?

• Increased power consumption

• Decreased signal strength

• Reduced servo speed

• Limited range of motion

In a C++ program using the Arduino Servo library, how do you initialize a servo to pin 9?

• myServo.attach(9);

• myServo.connect(9);

• myServo.bind(9);

• myServo.link(9);

What is the effect of calling `myServo.write(90);` in an Arduino sketch?

• The servo moves to 90 degrees

• The servo stops moving

• The servo detaches from the pin

• The servo moves to 180 degrees

Which of the following is a potential solution to power issues when controlling multiple servos?

• Use a higher voltage power supply

• Use a separate power supply for the servos

• Reduce the number of servos

• Increase the delay between servo movements
