The LED circuit is used to simulate power restoration at the moon base. This is achieved by placing the al-foil balls over 2 al-foil sheets to complete the wire circuit. | The LED circuit is used to simulate power restoration at the moon base.

- | A resistor is required to ensure that the LED does not burn out from the battery, or the battery does not provide too much voltage to the LED. You can use this [[http://led.linear1.org/ | + | A resistor is required to ensure that the LED does not burn out from the battery, or the battery does not provide too much voltage to the LED. You can use this [[http://ledcalculator.net|resistor calculator]] to find out what resistor you require based on the LED you have and what battery you are using. |

+ | As an example, you can see the following LED has a forward voltage (or voltage drop) of 5V and a forward current (or current rating) of 20mA. | ||

+ | This calculation shows we would need a 200 Ohm 1/8 watt resistor. When shopping for resistors, make sure you get a resistor that is 200 Ohm, the wattage is the minimum required so if you cannnot find a 200 Ohm 1/8 watt resistor, a 200 Ohm 1/2 or 1 watt resistor would be fine. | ||
