Hello
I was hoping that someone would be able to give me some pointers on how to wire up a LED and a headphone jack to a switch.
I'm pretty sure that I can follow http://www.instructables.com/id/How-to-Construct-a-35mm-Switch-diy/step6/null/ to wire up the jacks, and I know that I will need a 560 Ohm, 1/8w resistor to power my LED (don't have the exact specs, but I think it's 3.65vF, 10mA) on a 9V battery power supply, but what I'm not sure of is how to wire it up. I obviously only want the LED to light up when the corresponding jack is selected.
As a follow up to this, is it possible to put a higher value resistor in the circuit to decrease the light output from the LED? I don't want it to be blinding.
