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. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
