  4. Include a photo of your circuit with your LED turned on using VOUT. Based on the forward voltage in your LED and the resistance in your circuit, what is the voltage drop across the resistor and current through the LED? Assuming your LED acted like a resistor, what would the resistance of your LED be? - 10%
