Introduction to Arduino ( Part -II )

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

• digitalRead( ledPin, HIGH);

• analogWrite( ledPin, HIGH) ;

• digitalWrite( ledPin, LOW) ;

• analogRead( ledPin, LOW) ;

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

• "Serial.print" prints two line

• "Serial.println()" adds a new line

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

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

What will be the output of the above code ?

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

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

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

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

What will be output of the given Arduino program?

• LED will blink once in every 1 sec

• LED will blink once in every 0.5 sec

• LED will blink twice in every 1 sec

• LED will blink only one time then remain OFF

What will be output of the given Arduino program?

• LED will blink with increasing delay of 0.01 sec

• LED will blink with decreasing delay of 1 sec

• LED will blink with increasing delay of 0.1 sec

• LED will blink with delay of 3 sec

What is the value of “val” in the following program if the pin 12 is given 5V 3 times?

• NULL

• 3

• 2

• 1

What will the output for the code given , if executed on an Arduino UNO?

• 1

• 2

• 3

• 8

What will be the output of the following code given ?

• 8

• 12

• NULL

• 20

A current ratio of IC/IE is usually less than one and is called:

• omega

• beta

• theta

• alpha

Given that Ic = 2 mA and VCE= 10 V, determine R1 for the network of the fig.

• 85.23kΩ

• 86.52kΩ

• 75.62kΩ

• 80.62kΩ
