Unit 7 – Week 5 Quiz Answer
Assignment 5
Question 1)
Why interoperability is required in Internet of Things?
- Different control models
- Different programming languagesย
- Heterogeneous wireless communication protocolsย
- All of the above
Question 2)
Unique identification codes associated with device interoperability are:</b >
- Universal Product Code (UPC)ย
- Electronic Product Code (EPC)ย
- Uniform Resource Identifier (URI)ย
- All of these
Question 3)
The interoperability between devices and device users in terms of syntax is termed as:</b >
- Synthetic interoperability
- Syntactic interoperabilityย
- Both a and bย
- None of these
Question 4)
The UMB-A adaptor:
- Convert physical devices into virtually abstracted onesย
- converts local middleware’s message into global metadata’s messageย
- both a and bย
- none of these
Question 5)
Arduino UNO supports output supply voltage of:
- 5Vย
- 9V
- 3.3 V
- 5V, 3.3V
Question 6)
What is the servo library command to move the shaft of Servo motor back and forth?</b >
- Knob
- detach
- Sweepย
- writeย
Question 7)
An Arduino UNO has following number of analog inputs:
- 2
- 4
- 6
- 8
Question 8)
What is the functionality of the following code?
void setup() {ย
Serial.begin(9600);
}
void loop( {ย
int sensor Value = analogRead(A0);ย </i >
Serial.println(sensorValue);ย </i >
delay(1);
}
- Reads analog values from A0 only.
- Reads analog values from A0 and prints on the serial port/terminal only.
- Reads analog values from A0 and prints on the serial port over and over again after delay of 1 millisec.</span >
- None of these.
Question 9)
What is the functionality of the following code?
#include <Servo.h>
Servo myservo;ย
int potpin = 0; // potentiometer value initializationย </i >
int val;ย
void setup() {ย
myservo.attach(9);
}
void loop( {ย
val = analogRead(potpin);ย </i >
myservo.write(val);ย
delay(15);
}
- Writes values to servo motors only.
- Reads potentiometer values on A0 only.ย
- Reads potentiometer values on A0 and writes to servo controller in a loop after a delay 15 milliseconds.</span >
- None of these
