Following the example by lady ada here: RGB LED strip tutorial Using the STP16NF06 as suggested, wired properly, with a TLC 5940 driving them commanded by an arduino, nothing happens unless I hold the PCB in my hands. simply touching the pins of the mosfets, while a fade is running, turns them on u…

Logic level mosfets do not turn on, unless I touch them!

So for the OP.
This sounds like the grounds are not connected.
