accent led on nano biscotte

[whitmers]

I'm looking to to use the 3.3 accent pad on the nano biscotte, and frankly I have no idea to begin. What sort of LED can I easily mount on there since this is the first time i'm playing with this? I'd like to use it to try to make a crystal chamber. Any help or advise is welcomed.

You can attach a 3mm or 5mm LED to it (via wires), you would have to run the negative back to the battery(-). You might need a resistor depending on which color you decide to use.

is there a list somewhere for accent led resistances? ideally I want to do one without a resistor, something less for me to screw up.

Look up Ohm's law. It's how resistance values are calculated. The formulas are in the NB manual as well. It's been covered several times on the forums. I know I've demonstrated it several times here. *Waves hand* Use the search button, it is your friend.

Accent LEDs are pretty much gonna need a resistor. It's exceedingly hard to build around that requirement. Wiring in a resistor isn't hard. You just add it to either the positive OR the negative wire for the accent LED.

http://led.linear1.org/1led.wiz is what I use to figure out resistor values. You can also choose to do the math as well. Both are valid options.

Keep in mind that if you run an accent LED on the 3.3v pad that you will need a recharge port. Even in deep sleep mode, the accent LED would remain on and drain your battery, I have just wired it in parallel with the main LED, like you would do on a stunt saber, and it won't come on until you power on the saber.
