Camera Programming with Arduino (ShieldBot)

What will the robot do if signature 2 is detected?

Choose all correct answers.

• play a tone

• not play a tone

• drive forward

• loop again and look for signature one

True or False. In order for the robot to detect if the camera sees a matching parking marker, the colors of the markers must first be set up as signatures.

• True

• False

What is the purpose of this code:

while(whiskerLeft == released) {

delay(10);

}

• It slows down the code execution for the entire program.

• It keeps the code execution in one place, until the left whisker is pressed.

• It keeps the code execution in one place, until the left whisker is released.

• It keeps the void loop() section from running more than once.

What is the purpose of this code:

storedColor = pixy.ccc.blocks[0]. M_signature;

• It stores the name of the color signature in the variable

• It stores the numerical index of the color signature in the variable.

• It compares the value stored in the variable with the color signature.

The PixyCam can be configured to store up to 7 colors as:

• color names

• color arrays

• color signatures

• color bytes

What type of variable is best suited to store a whole number?

• boolean

• string

• float

• integer

When does the following piece of code evaluate as true?

if (pixy.ccc.blocks[0].m_signature == storedColor)

• When there are 0 colored blocks/blobs visible by the camera

• Never

• When the signature of the largest block/blob matches the value in storedColor

• When the signature of the smallest block/blob matches the value in storedColor

True or False. A red cube should register as a different color signature than a red ball. 

• True

• False

True or False. "Red" must be stored as color signature 1.

• True

• False

How long will the robot stay at this line of code in the program before moving on?

delay(10);

• 10 seconds

• 10 milliseconds

• 10 microseconds

• 10 minutes
