Thanks!

I'm trying to follow a tutorial to use a RGB strip with a Rasbperry Pi (http://dordnung.de/raspberrypi-ledstrip/). In it, it says I need: Three MOSFET's (e.g IRLZ34N) * Important is a threshold voltage of max. 3.3V (Mostly marked by an 'L' (Logic-Level) in the name) After searching online, I found t...

Why do I need separate resistors? Couldn't I just have the legs of each LED all on the same circuit (ie, all the reds together, all the greens, etc) so controlling sending a light to one GPIO lights all the LEDs?

I've done some simple blinking a led sort of stuff with the Rasbperry Pi, but I want to take it up a notch and maybe make something useful. I was toying with the idea of making a simple RGB "mood lamp." with the pi and some rgb leds in a frosted glass vase that I coudl control what color they glow, ...
