Which of the following DOES NOT describe how serial monitor works?

• It receives data from Arduino and display data on screen.

• It sends data (command) from PC to Arduino.

• In order to use serial monitor, we must connect Arduino and PC via USB cable.

• It can receive data and display it, but cannot send data to Arduino.

• The text Hello will appear on the serial monitor page repeatedly.

• The text Hello will appear on the serial monitor page twice.

• The text Hello will appear on the serial monitor page once only.

• The text Hello will not appear on the serial monitor page.

How will you describe the result of the statement Serial.println ("Hello"); on the serial monitor which is written under the void loop?

• The text Hello will appear on the serial monitor page repeatedly.

• The text Hello will appear on the serial monitor page twice.

• The text Hello will appear on the serial monitor page once only.

Daphne encountered an error in uploading her codes. What do you think is missing in her codes?

• There is no opening curly bracket right after the void setup.

• There is no semicolon ; in statement in line number 2.

• Closing curly bracket in line 3 must be removed.

• Wrong spelling of command print line.

Vince wants the texts "Good Morning" to display on the serial monitor repeatedly. What must he do in his sketch?

• Remove Serial.begin(9600); in the void setup and transfer it in the void loop.

• Remove Serial.println("Good Morning"); in the void setup and transfer it in the void loop.

• Transfer both Serial.begin(9600); and Serial.println("Good Morning"); in the void loop.

• His sketch is correct and no need to edit the codes.
