In this episode of Electronic Basics I will show you how to use N-channel and P-channel MOSFETs as switches in order to turn on and off your electronic load with a control signal. This way you can, for example, use your Arduino to control loads that require more current than the output of the Arduino can handle.

Thank you for demonstrating at 2:42 how sensitive MOSFETS with floating pins are, I always hear about using a pull-down resistor to fix them but never saw it inaction.
I just don't understand why you don't have at least a million subscribers. These are extremely high quality videos, short and to the point, with tons of information. Love your videos man
Thanks mate, I guess electronics is simply not mainstream.
It should be, screw gaming channels, I mean I actually get to learn something interesting from your videos. They really are inspiring me to go into computer/electrical engineering.
+David Serrano I understand most of what says and goes over in his videos. What other channels produce short, quick , quality clips of information.
Cuz there are not many people like me for example, who don't get a single word of what he says but still watch the video :D
+Dargmuesli His videos are great to watch, especially to see what he makes. it doesn't matter if you don't understand completely, as long as you take an interest in what he's doing.
Took a while, but I managed to make a mosfet driver... And now I understand why I burned a lot of mosfet in this past... Damn internal capacitance
hahahhaha
These are extremely high information videos, Love your videos man.
Thanks
wow such an effort to make those videos, I really appreciate the great quality and passion they were done with, thank you so much for making it way way more fun to all electronics students out there.
Thank you so much for this video! You boiled everything down so eloquently, and the modest, but precise visual aids drove everything home. This is gold for anyone learning MOSFET switching!
I needed this for a project! Thank you so much for explaining it so well!
Love these vids, currently doing a project involving controlling different loads with the electricity sent through nerves, and this vid really helped me understand these "bundles of joy" (especially when it comes to the magical smoke)
Thanks for the straight forward update. You are doing a very appreciated job here!
I had difficulty following this. I'll try rewatching and following along at home and see if that helps. thanks for your videos, even when I am confused, I enjoy learning there is more to things than a couple of steps.
Looking at your style of drawing brings out how greatly organised and clear your mind is....the greatest inspiration for me to keep sticking to the video...
@3:48, P-Channel MOSFET, you say voltage on the gate (VGS) shuts off the MOSFET, but the scope shows the opposite behavior.
Love the electronics basics videos! Keep it up!
me too :)
You have a really good handwriting!
I love watching him draw the diagrams and labels. Even the highlighter is strangely comforting, kind of like an ASMR vid for nerds, lol
i wish i could distinguish his 1 from lambda
I know, by far the best I’ve seen on a lefty
Thanks
Thank you for this. Also, the additional resources you linked are much appreciated. This will help a lot.
I learn all the relevant information very quickly from you sir. It feels like you invented electronics! 😂
Wow greatScott! Your videos are so amazing. You are so knowledgable! Thank you for sharing your knowledge with us!
Thanks a lot for this, you are the only person who explained the circuit of a mosfet completely
I've been searching for half an hour if "n" os "p" type is needed to my project. Thank you for the answer! ;)
This is exactly the information I needed. I wish I could like it twice
These electronics basics videos are awesome, I think this one was really nice especially the way he explains the datasheet !
I'm ready for MOSFETs part 2... drivers! Excellent videos. I have a great time watching them.
Excellent Video / training session / reference material. Thanks a ton !!!
Everytime +GreatScott uploads a video it just feel like Christmas :) the videos are just top notch 👍
The right channel for electronics tutorial
wow, so many information into one simple videos, you are really do a great job man keep it up!
I love the electronics basics videos and I have heard so much about this but never understood it, thanks great scott!
the best explanation till now!
None of these videos make any sense to me but I can't stop watching them. You have a great skill.
Great vid, thanks for uploading :)
Thanks a lot, Brother. Great Work. This kind of work demands a lot of effort, My best wishes for your new projects.
This video came exatly when i needed!
Really great keep on doing the good work
Well, thank you sooo much. I like your style of explanation very much
this is the best electronics channel ever
Joel is right you should have a million subscribers. I was looking for easy way to control heating, and laser circuit with PSoC 4. your video helps me to solve the problem. thank you.
frankly, i didn't understand much when i first saw this video, but after learning this concept in class and then coming back here helped me completely understand mosfets
this learning process of practical after theory works best for me
thank you for creating such video
Another great video from you!!! Thanks!!
props as always great vid
Thank You so much for the videos. Really love it...
Whoa. Somehow noone mentions the internal capacitance and the 70V spikes that it's causing! Thank you for the video!!
You're awesome man, thank you!
great job from great scott
You’re probably The most useful electronics video Channel
love this channel
Scott, you're great.
Спасибо. Очень нужны такие видео!
thx about the tip of the 10k resister you made my day thx so much
As soon as I heard his voice and recognized who it was he got the "thumbs up" Excellent videos all the time from this man!!!!!!!!!!!!!!!!!!!!!!
Sir its a very very informative video for a beginner like me,thank you hope for more videos in this series. 👍👍👍
Keep it up, nice video, thank you for sharing it :)
I've designed MOSFET circuit thanks to this video. If it won't catch on fire I'll give a like :)
It's interesting, never thought so deep about MOSFETs
thx man helped me a lot
Great video! keep doing this!
Thanks for the information
very nice tutorial...you have us rookies , knowing more and more
what an introduction tune
Awesome video.
Thank you very much to all of your teem
Once again I learned something new. :-)
I really like the way you create the Circuits with cut eagle-printouts and a Pen. Very nice to follw :)
Very nice explained
So cool to understand
Another great video!
I really enjoy your videos.
I learned electronic principles years ago, but much of what I learned has regressed to where I only remember how isolated components work, but not necessarily how they affect circuits when combined with other components. I'd really enjoy hearing you walk through the theory of operation for a simple circuit explaining how the current flows and is affected by each segment through the circuit. Just in case you are ever looking for a topic your audience would enjoy... I'd vote for this :-)
Keep up the great work!
Thanks. I put it on my to do list.
Excellent 👍
This is extremely clear.
great video
Heilige Bismarck ! Sehr schoen ausgefuhrte lehrstueck !
love you brother. great videos.☺☺☺☺☺
this elaboration i wish u every succes for
You have the smoothest voice ever. I wish i had money to have you read to me
I didn't come here to get the remedial lecture. Noting your sense of humor, I subbed anyway.
Awesome tutorial!
It helped me get my FETs right!
You should probably do one about winding transformers.
2:23 "But before going too much into the 'teewee' " haha :D.
Your accent is funny and your work is very good!
Keep it up!! Great vid!
It will help a lot 😊
You are the best!
Thanks a lot for your good explained videos. I did not know that you got a peak when Arduino switch off. It is good information and I am impressed about your knowledge. Thanks a lot and have a great weekend. 🇧🇻👍
Hi I love your videos.
Thank you for your helpful video ?
I have a question about the efficient formular at 0:30, where do you take the value of voltage 5.15 and 6 V and the current 3.3A from?
Brilliant video mate!
Keep the up the impeccable work!
Links to the formulas used would also be appreciated (if possible).
Thanks!!
Scott, i am a hobbiest that love electronics, i used to love your inventions, your latest videos are too technical and complex, i hope you can change them to easier subjects, greetings from argentina
This playlist is going backwards.
Loved this series!
I like the cut out pieces of paper, good idea. :D
Hey dude,, I got much knowledge from your videos , much thankful for that ,, I stuck at chosing mosfets at high frequency , I want to use mosfets at 1 MHz ..!
The video is awesome and the time spent is a quality time. Is there a video describing the working of P-Channel MOSFET as a high side switch as well as low side switch?
very nice
Thanks!
thank you for the links. I'm trying to move beyond my 16 channel relay board (that clicks very loud) into using mosfets - just very wary because the supply is high amperage (10A/12v)
You are amazing enough that you (and others) have inspired me to do electrical engineering at Oregon State University. Thanks for being so damn awesome!
So basically it can used as an voltage amplifier
Noiiceee ❤
hello, thanks a lot for a great job. in order to control a load between 1amp to 30amp, what do you suggest to use?
Every video I feel more stupid..
Me too :(
If you don't want to watch basic electronic stuff, you're not obliged ;)
Thats normal, its just because you starting to realize how much there is to know, therefore how litle you know : )
Don't we all...
If you want transistor tutorial stuff, I would watch a channel called Ben Eater. Yet he only explains transistors, logic gates, and complex logic circuits(his 8 bit PC), not other components.
“The more I know, the more I realize I know nothing.” Cit. Socrates
Want a video on making an efficient inverter from GreatScott!
Hi GreatScott! how you feel to use opto-couple/opto-transistor on Arduino pins?? you will get then a complete voltage and a current isolation ( when use 2 separate power source for PCB/Arduino and MOSFET ) from MOSFET + small amount of hfe.
Minus can be opto-couple/opto-transistor frequency of switching.
Many Thx and I wait for other videos.
Human can learn all LIFE and in the end HE realise the he die stupid :)
Learning is never ending story!!!! :)
good video
wow this video taught me how to make touch sensor :D
Nice Video!
I wanted to use an IRFz34N for a simple speed control circuit to my linear actuator (5-8 amps) controlled by my micro-controller.
I ordered the parts and I have the pull down resister, but am I limited as to the switching frequency due to the issues you mention?
Hi Greatscott, very nice video as usual. I have a logic level n-channel mosfet(FQP30N06L) and switchin on-off by appliying 0 and 3.3v Vgs from a gpio pin. Drain side I have a load operates at +5V. After the pc turns off, PC pulls up +5V all GPIO pins(Vgs). As a result after pc turns off it turns on the load again. How can I prevent the gate voltage if more than 5V at the logic level mosfet? Best.
