I am building a PC 2.0 saber with a tri-rebel BBW. The saber will also have 2 accent LEDs, one green and one red. I will have two blue momentary switches, one ring and one dot.
I've read the pc 2.0 manual and I understood a lot of things I wasn't sure, about the whole saber building, but the resistors are still something I'm not quite sure.
The green LED is 2.2v 25mAh and the red one 2v 20mAh. If I understood correctly, the user decides what he wants. So let's say I want to green one at arround 13mAh and the red one a little bit brighter, about 15mAh. 82 ohm would be about it, meaning I have to get http://www.thecustomsabershop.com/82ohm-14w-resistor-P23.aspx good so far?
If the resistor is correct, do I need two? or just one? I did not understand how the wiring for the accent LEDs resistors work, with the resistor footprint pads. Are they in serie or in parrallel? I'd like some info on how the accent LEDs are wired. Thank you.
For the rest, if I understand correctly, the main LED doesn't need a resistor, only the FoC LED? I recall the white LED is 3.1v and can be driven up to 1A. The resistor would be something like 4.3 ohm. Good so far?
Would I be better with a 4.7ohm 5w http://www.thecustomsabershop.com/47ohm-5w-resistor-P492.aspx or a 3.9 ohm 5w http://www.thecustomsabershop.com/39ohm-5w-resistor-P17.aspx ?
Now for the switches, they are wired to the 3.3v pad, right? They are both already 3.3v and 20mAh. If the max mAh from the pad is 18, do I still need a resistor?
I think this covers pretty much my questions. I want to be sure to buy the right stuff and to be sure I understand.
Thanks a lot
