What is a loop?

• A type of storage for us to store information we use in a code

• Allows us to run the code many times

• The type of information we store in a code

What is the variable of the following statement:

int count = 3;

• int

• count

• 3

• ;

What does this function does?

digitalWrite ()

• writes output value to either HIGH or LOW

• writes output value using PWM sequence

• sets a pin to either INPUT or OUTPUT

• pauses the program

What does this function does?

pinMode ()

• writes output value to either HIGH or LOW

• writes output value using PWM sequence

• sets a pin to either INPUT or OUTPUT

• pauses the program

What happens when you run this code:

digitalWrite (red, HIGH);

delay (5000);

• The red LED lights up for 5000 seconds

• The red LED turns off for 5000 seconds

• The red LED turns on for 5 seconds

Why is a resistor important?

• It isn't important
• It increases the power of a circuit
• It controls the flow of electricity by lessening it to a certain amount

What is an LED?
