LED

• Light Exposing Diode

• Light Exposing Device

• Light Emitting Device

• Light Emitting Diode

An electrical component that opposes or limits the passage of electricity. The amount of ohms offered is displayed as color-bands using a color code.

• Capacitor

• Resistor

• Inductor

• Transistor

Each line of code in Arduino requires a ____ at the end.

• ;

• :

• { }

• //

The longer lead of a light-emitting diode is known as what?

• Longpin

• The Anode (positive)

• The Cathode (negative)

The schematic symbol represents...

• a capacitor

• a transistor

• a light-emitting diode

• a resistor

digitalWrite(13, LOW); turns the light

What does pressing the check-mark do when working with your code?

• Saves your work.
• Downloads your code onto the arduino board.
• Checks your code for mistakes.
• Checks to see if the arduino is connected to the computer.
