Link to the Joe knows electronics that I got my 2N7000 are in the page above and added to my amazon store front down lower on this list.

N channel enhancement mode MOSFETs, like the 2N7000 can be used as a replacement for the NPN BJT as a switch when you don't want to depend on current from the signal.

Source being ground and Drain being high voltage has messed me up before I re-watched your video.
I had mine set up backwards apparently.
Thank you so much!

[@danialdunson]

thanks for the video. the data-sheet is reversed on page 1, but is consistent with your diagram on page 8. wow

[@spudnickuk]

Very well explained
Maybe one day you could do a video of two MOSFETs driven by a chip

[@SDesigns3D]

Still watching all your vids! Your channel is such a goldmine! That dang face still scares me though...trippy man lol

[@Electronzap]

Ha! He's meant to look determined lol. Glad you enjoy the videos!

[@sparkden]

perfect explaining!

Can i use it with control circuit with finger print without direct touch

[@Electronzap]

I haven't worked with any finger print readers, but there's got to be some way to use them to control a transistor if that is desirable.

Thank you.

Should the driver be a processor pin or an I/O pin (e.g. from a MCP23017 I/O expander) instead of a switch, would there be a need for a series resistor, say 100 ohm, between the I/O pin and the gate of the mosfet? This to avoid excessive current flow during switching moments?

[@jontech9978]

Awesome job. Great IC to work with

[@Electronzap]

Thanks!

[@sudheerkumar5966]

Very good

[@johnmoor8839]

i thought that was the symbol for a p channel J fet ?

[@Electronzap]

JFETs usually have the arrow at the gate.

[@paulf1071]

@@Electronzap Yeah, the symbol used in the schematic on the left of the printout looks wrong to me. Is that not the symbol for a PMOS depletion-mode FET?? (The Drain-to-Source line is drawn as solid instead of broken, and the arrow is facing out, instead of in).

[@PerspectiveEngineer]

Clean...

[@Electronzap]

Thanks!

[@sliderulelover]

There is current flow. Current flows from drain to source called ID. I think you mean there's no current flow from gate to source or gate to drain.
