Red Leds Help?
« on: June 13, 2008, 03:21:19 PM »
Hi. Recently i did the trigger mods for the psp...i used a red led and a green led. both leds work (when tested seperately) I.e. with a battery
but when i soldered them to the psp only the red led lights up. (the positive voltage goes through red first then to green)
I tried the other way (Positive voltage goes through green first then red) and Only Green lighted up this time.
[i used a 10ohm resister also]
How can i make Both Green And Red Led Light up at the same time?
(Yes i did use the search button and i couldnt find it)

try not using the resistor if you can risk the leds

what are the specs of your leds
