Arduino Servo Control Quiz

What components are necessary to control a servo with a potentiometer?

• Potentiometer, servo, LED, resistor, battery

• Arduino, capacitor, LED, resistor, power supply

• Arduino, servo, LED, breadboard, resistor

• Arduino, breadboard, potentiometer, servo, jumper wires, additional power source

What role does the potentiometer play in controlling the servo?

• It functions as a position sensor

• It serves as a signal amplifier

• It acts as a power source

• It provides stability to the servo's motion

What is the primary difference between PWM signals for servos and the analogWrite command?

• There is no difference in the signals

• AnalogWrite uses a digital signal

• Servos use a lower frequency signal

• Servos use a higher frequency signal

What does a duty cycle of 5 to 10 percent represent in servo control?

• The servo's speed

• The servo's power consumption

• The range of motion from 0 to 180 degrees

• The frequency of the PWM signal

How is the servo's position determined by the input signal?

• By the signal's frequency

• Through the signal's amplitude

• Based on the signal's voltage

• Using the signal's duty cycle

What is the purpose of mapping the sensor value from 0 to 1023 to 0 to 180?

• To decrease the servo's power consumption

• To match the servo's range of motion

• To convert digital signal to analog

• To increase the servo's speed

What is the inverse of a 50 Hz frequency used for in the Arduino code?

• To calculate the servo's speed

• To set the PWM signal period

• To adjust the servo's power consumption

• To determine the servo's range of motion

Why might a servo exhibit twitchy motion, and how can it be mitigated?

• By using a higher frequency PWM signal

• By providing power from a separate source

• By using a digital signal instead of PWM

• By increasing the duty cycle

What is the correct pulse width for achieving 0 and 180 degrees of servo motion?

• 1 ms for 0 degrees and 2 ms for 180 degrees

• 0.5 ms for 0 degrees and 2.3 ms for 180 degrees

• 1.5 ms for both 0 and 180 degrees

• 2 ms for 0 degrees and 2.5 ms for 180 degrees

Why is it recommended to power larger servos with an external source?

• To increase the servo's range of motion

• To reduce the servo's response time

• To enhance the PWM signal's clarity

• To prevent overloading the Arduino's power supply
