Which type of sensor is commonly used for measuring distance in an Arduino project?
What are the typical pin names used to connect an ultrasonic sensor to an Arduino?
SDA and SCL
TRIG and ECHO
DATA and CLK
VCC and GND
Which function is used to measure the time taken for the echo to return to the ultrasonic sensor?
What is the typical formula used to calculate distance using an ultrasonic sensor?
Distance = (Speed of Light × Time) / 2
Distance = (Speed of Sound × Time)
Distance = (Speed of Light × Time)
Distance = (Speed of Sound × Time) / 2
How is the duration of the pulse measured in an ultrasonic sensor calculated in Arduino code?
duration = pulseIn(echoPin, HIGH);
duration = millis();
duration = digitalRead(echoPin)
duration = analogRead(echoPin);
What is the speed of sound used in the calculation of distance in air (in cm/us)?
3.31
0.034
0.21
2.43
What is the primary function of the TRIG pin in an ultrasonic sensor setup with Arduino?
To receive the reflected ultrasonic signal
To send the initial ultrasonic pulse
To provide power to the sensor
To ground the sensor
What is the main purpose of the ECHO pin in an ultrasonic sensor setup?
To provide power
To send the initial ultrasonic pulse
To provide power to the sensoR
To receive the reflected ultrasonic signal and measure the time duration
