Hi there, I have a series of LEDs that I need to get running. i plan to use this series in my car as a cutom LED gauge cluster (you know, speedometer, fuel, engine heat). Anyhow, I've got 17 white LEDs
Specs:
Voltage Supply = Unkown
17 LEDs
3.1 Voltage
20 - 30 mA
I was wondering if anyone may know the amount off voltage needed to power something like this and also the best way to wire them (i was thinking series).
Using a resistor calculator I've been told that I need 100 oHm resitistors. (this was with a 12V example) which doesn't make sense as the 12V's couldn't posibly illuminate this seires.
Thanks in advance
Darryl
