Arduino

___________ are pre built circuit boards that fit on top of Android.

• Sensor

• Breadboard

• Data Types

• Sheilds

What does this line of code do? counter++;

• Increment counter by an amount that depends on its definition.

• This is not a legal statement in the Arduino language.

• Adds 1 to the variable counter

• None of the above

Is there anything wrong with this line of code, if yes, what? if(myVar = true) Serial.println("The light is ON");

• There needs to be a space after the if keyword.

• The = should be ==

• There is nothing wrong.

• An if statement must use braces.

What is the value of foo when these lines of code are executed? foo = 12; foo = foo % 10;

• 1

• 2

• 1.2

• None of above

What does this line of code do? temp = !temp;

• Sets the variable temp to its logical compliment.

• Converts the variable temp to a boolean value.

• The line is not a legal Arduino statement.

• Preforms a factorial calculation.

What is the range of numbers you can store in a variable of type byte?

• 0 to 65535

• -128 to 127

• 0 to 255

• 0 to 9

To subtract 1 from a variable counter, you can use the following statement(s) (check all that apply)

• counter- = 1;

• counter = counter -1;

• counter--;

• --counter;

• None of above

A program written with the IDE for Arduino is called _________

• IDE source

• Cryptography

• Sketch

• Source code

What is wrong with the following

/*Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain.*/

int led = 13;

VOID setup() {

pinMode(led, INPUT);

}

VOID loop() {

digitalWrite(led, HIGH);

delay(1000);

digitalWrite(led, LOW);

delay(1000);

}

• All the code

• Void

• High and Low

• Low and High

Which statement when executed provides 5V @ the 13th pin on Arduino UNO board in order to turn ON the LED?

• DigitalWrite(13,HIGH);

• DigitalWrite(LED,HIGH);

• DigitalWrite(13,LOW);

• DigitalWrite(LED,LOW);
