Hello guys,
I am currently trying to run a motor off a chip (PICAXE 08M) and I am using a 2N7000 N-Type Enhancement MOSFET. The gate of the MOSFET is connected to the output of the chip (~5v) while the source is connected to Ground and the Drain to 5v supply. (I have also connected a diode in case of any back emf..)
Every time I try to test if the MOSFET is working it seems like it dies. I dont actually connect a resistor in series with the gate though, but I thought that no current would go into the gate anyway so why would I need to?
Can someone please explain why I must connect a resistor in series and if so what value? (the highest one I have is 400k, is that enough?)
Thanks.
