Quizz 2

You can write a digital output to a specific pin on the Arduino board with the help of:

• analogWrite( ledPin, HIGH) ;

• analogRead( ledPin, LOW) ;

• digitalWrite( ledPin, LOW) ;

• digitalRead( ledPin, HIGH);

What is the difference between Serial.print() and Serial.println() in Arduino

programming?

• "Serial.println()" don't add a new line

• "Serial.print" prints two line

• "Serial.println()" adds a new line

• "Serial.print" prints the output in multiple lines

What will be the output of the above code ?

• LED connected at pin 13 will blink with delay of 1 sec

• LED connected at pin 13 will blink with delay of 0.5 sec

• LED connected at pin 13 will remain in OFF state always

• LED connected at pin 13 will remain in ON state always

Arduino Codes are referred to as ________ in the Arduino IDE.

• drawings

• sketches

• connection

• links

What is the difference between an IDE and a compiler?

• The compiler and the IDE are the same

  thing

• The compiler links the code to the respective files and the IDE takes it from there

• The IDE executes the code while the compiler gives a graphical environment for writing the code

• The compiler executes the code while the IDE gives a graphical environment for writing the code

Is the Arduino code an Object-Oriented programming language or a Procedural

programming language?
