What three sections of code did you have in the Arduino project sketch?

• Comment block, variable definitions, and run section.

• Comment block, if section, and loop function.

• Variable definitions, loop function, and finalize function.

• Variable definitions, setup function, and loop function.

How long is the LED on?

digitalWrite(13, HIGH);   
delay(1000);   
digitalWrite(13, LOW);   
delay(1000); 

• 1000 seconds
• 100 seconds
• 1 second
• 100 milliseconds

Which statement do you change to alter the time?
void setup()
{  
pinMode(13, OUTPUT);
}
void loop()
{  
digitalWrite(13, HIGH);    delay(1000);   
digitalWrite(13, LOW);    delay(1000); 
}

• delay
• void loop
• digitalWrite
• pinMode

Which means keep going forever?
void setup()
{  
pinMode(13, OUTPUT);
}
void loop()
{  
digitalWrite(13, HIGH);    delay(1000);   
digitalWrite(13, LOW);    delay(1000); 
}

• OUTPUT
• void setup
• void loop
• digitalWrite
