LED questions
« on: December 09, 2009, 11:28:21 PM »
1) what is the maximum voltage my LED can take?
2) Why must there be a resistor in series of the LED in a circuit? can we do without one?

just some questions :D

1. You should probably be more concerned about current than voltage. Pretty much any LED you get is going to be able to handle pedal voltages, provided you use an appropriate current limiting resistor.

2. If you don't use a resistor, the full current of your power source passes through the LED, straight to ground. Not desirable.

3. Parallel.

If you're not doing it for yourself, it's not DIY. ;)
