RGB Mosfet control. Which leg to pull to the hround
-
There are different schematics on the net. One pull the signal to the ground
Others the load.
So which one is better?

@moskovskiy82 theoretical difference: http://www.learningaboutelectronics.com/Articles/Difference-between-a-NPN-and-a-PNP-transistor
Practical difference: not much in the Arduino home automation world. But I prefer NPN since that's what the MySensors examples use.

Imo in all cases the pulldown should be on the controlling pin (gate). Otherwise listen to @mfalkvidd

@moskovskiy82 Have a look at my Fire pit RGB striplight controller, The Mosfets in that project run very cool (can't detect any heat rise at all) with 10m of rgb strip lighting connected.
