Arduino Ultrasonic Sensor and Parking System Quiz

What is the primary function of the ultrasonic sensor in this project?

• To detect temperature changes

• To control the Arduino board

• To measure the distance of an object

• To emit light waves

Which component is NOT included in the basic starter kit?

• Ultrasonic sensor

• Arduino board

• Breadboard

• USB cable

What is the role of the RGB LED in the circuit?

• To emit sound

• To indicate distance with colors

• To power the circuit

• To measure distance

Which pin on the Arduino is used for the trigger signal of the ultrasonic sensor?

• Pin 5

• Pin 7

• Pin 8

• Pin 6

What happens when an object is detected closer than 10 cm to the sensor?

• The circuit powers off

• The buzzer beeps slowly

• The LED glows red

• The LED glows green

In the parking sensor system, what color does the RGB LED glow when the object is further than 30 cm?

• Red

• Green

• Blue

• Yellow

What is the purpose of creating a custom 'beep' block in the code?

• To power the Arduino board

• To change the LED color

• To simplify the code for repeated beeps

• To adjust the sensor's sensitivity

How does the buzzer behave when the object is between 10 cm and 30 cm?

• It beeps very fast

• It does not beep

• It beeps slowly

• It beeps at a moderate speed

What additional feature can be added to improve the parking sensor system?

• A larger breadboard

• A temperature sensor

• A push button

• A second ultrasonic sensor

What is the significance of the PWM pins in this project?

• They are not used in this project

• They connect the ultrasonic sensor

• They control the RGB LED colors

• They power the Arduino board
