Some professional clock kits use 3 x 2n7000 MOSFETs to drive 6 rgb leds. 
The gates are connected directly to the microcontroller pins. I tried that 
and it works fine. My problem is that the controller and the MOSFETs are 
not on the same PCB. 

If I power up the two boards without the wires between microcontroller pins 
and MOSFET gates, there is a good chance to destroy the MOSFETs, I killed a 
lot of them :-)

Unfortunately, I’m not an electronic engineer, so my question is how can I 
protect the MOSFETs. I have tried several things on the breadboard. 
Connecting a 1M resistor between gate and ground and a diode between 
connector and gate seams to do the job, but I’m not sure if that is the 
correct solution.
