Electronics - Using an NPN Transistor as a Switch 

this is perfect. i've wasted about an hour watching so many videos explaining this in such depth, when all i needed was a simple demonstration. thank you!

I've been trying to wrap my head around transistors for a long time. You connected all of the dots for me in 6 minutes. Really useful viewing for the concepts.

This was by far the best explanation about transistors I ever found. Very well done Michael.

Not to pile on the following comments, but this 6 minute video/example explained more to me about transistors than 2 hours of other videos explaing what Transistors are. I now know exactly how to use Transistors in my project. Thank you for making this video.

Thank you for this tutorial. It was very to the point, which most seem to lack.

The same thing is getting explained in 20 min videos, but at the end I got nothing. Your video is super simple and to the point. Thanks a lot!!

thank you.. As many times as I have used them.. i learned more in a min with you then years.. thanks for the video...

this is the BEST practical demonstration of using a transistor as a switch. Def this one for practical and "great Scott" for theory. please do more!

the Scorched Earth breadboard absolutely made my morning!!!

Thanks so much for the dumbed down explanation of what NPN is. Makes it easier to understand that emitter, base, collector

Good vid, no filler, all info, good job!

Great vid. After watching a 90 year old explain this in about 3 hours. I still didn't understand. You did it perfectly in about 6 minutes

nice video. I couldn't find a transistor tutorial dealing with practical application for beginners. this gave me exactly the information I needed to have. Thanks!

Short and to the point. Thanks. I must've watched about five videos before I found this one.

This Is the first transistor video that I have seen that actually explains how it works, All you need is a good camera man and you are set!

Great video, straight to the point and useful. 2 things: First of all, the name transistor has nothing to do with the number of pins, 3. The prefix you're thinking of is "tri" not "trans". Anyway, the second item is that NPN does not stand for negative, positive, negative; that is, the "layers" of silicon are not called "negative" or "positive". Instead, they stand for "n-type" and "p-type" doped silicon. If you would like to learn about doped silicon and what these letters stand for, I'd recommend searching "how do transistors work" and instead of finding a video on how to use them, find one that explains how they function. Have a great day!

from the other transistor vids yours was the most straight forward and simple one so i finally got it "subbed"

Thanks, this helped a lot, all the other tutorials are confusing and don't make sense.

Thanks mate. I was trying to use a transistor for my 5v motor. You just solved the issue.

Nicely done, you explained the functions of NPN transistors and showed simplistically how to wire them in. That's what I wanted, thank you :)

Thanks buddy, I'm new to electronics and this video made it easy to digest the workings of a transistor.

This is a great video. It explains how transistor works in the simplest form. Keep up the good work.

Very well explained and demonstrated.

Thanks for a simple and informative video.

Very useful and easy to understand video!

Simple. The best explanation so far! Thanks Sir!

thanx michael - at long last an easy to understand tutorial about the switching option of a transistor. great to watch - thank you for sharing. yayyyyy

This video completely delivers on its promise. I can see how this would solve a problem with integrating Arduino and the Adafruit fx board. Thank you so much.

Simple and instructive explanation, thanks!

Thanks for the video. Was going to use one in place of a switch on a laser pointer, this answered some questions I had!

very concise and informative video. Thank You!

thank you for the vid, I was trying to figure something out with a project and this helped a lot!

I've watched 10+ videos and yours was the best!! hats off to you

Thanks for posting this, great example and explanation

Very instructive and easy to understand. Thank you very much!

Hi, I'm student from korea, and I really thank you for your explaining.

Thank you Michael! Very easy to follow.

I finally understand how they work i m new on this and you are the firth on youtube explaining the way i can understand tanks

Very well explained. Thank you

thank you for the video. was looking for the basic working of transistor

This explained it very well, thanks.

Thanks Michael, this was very helpful!

Michael, Thank You for this very elementary explanation of a NPN Transistor. I have searched, read and watch so many poor examples that I was total confused about the proper wiring of the NPN. This video was exactly what I needed. Thanks Again

Thanks, I needed this. I'm using it to set off a reed switch. It uses very little currant.

Fabulous tutorial by you

bro! thx for this vid understood everything i needed to, thanks again man!

awesome demo

Well I must say after watching this video and your other video on how to tell the difference with the pnp and npn you have made me fully understand how these work which in turn I can now start to complete a project that just kept failing. the NPN cures the problem. Thanks a million and I have subscribed to your channel

Thank you so very much for clear demonstration...please keep up the great job....Isam

thanks dude, couldn't get mine to work until I watched this

Thank you so much for your video, that's what i needed to know to figure out the circuit im working on.

Thank you! finally a good explanation fo a transistor.

finally, I understand how it works. I watched many videos about transistors and didn't really get it. Your video showed the transistor by example. THANKS man! :)

good video. very clear explanation

Thanks, I finally understand how they work!

great video i look forward to learning more about these i am thinking of getting an arduino

Thanks man , any info is great those are clear instructions.

I love the demonstration 👍🏻

Excellent tutorial, Michael! A simple topic, to be sure, but many noobs (we ALL were, once) will find it helpful. I was also surprised at the pin out designations for the NPN. I'm gonna' have to look closer at the datasheets. Well done! joe

Thank you Michale judge, it's very informative and clear explanation of NPN transistor, good job dude..

This was very helpful. Thanks!

Great demonstration use of NPN, it is best for basic thanks alot

fantastic explanation. Thank you!

Thanks Michael awesome and clean tut. thanks!

Thank you, it was very helpful

Great job man , thanks for the help .

michael, thanking you for your video. It has some time made, and i was searching some to explain. Your demo is the most easy to understand and a great way to show it. I always had thinked that, analogic electronics is more stable than digital. I've been seen nowadays youtube shorts, and there's proyects using this. But the most important, is expain how they works.

truly helpful video....for new beginners

Nice and simple -- thanks!

Thanks this was very helpful

very very nice explanation... i already know all of this but i like looking at new explanations and yours are awesome... congrats and thank you mate

Thanks a lot bro you explain is so perfect

Thanks for this video. It helped a lot for my hobby project :)

Thanks miki!! I love ur explanation!

Michael I am going to learn a lot from you! thanks for your videos

"Good"; Thank You, thank you very much... Do you have ANY additional videos on transistors or transistor technology? Let me know...

This was good explained. For it is possible to online simulate transistor some transistor circuits in simulate section of cirvirlab

Thank you. Beautiful video.

Thanks Michael. Good one mate.

good video great information well done

Thanks, I got this to work.

your video is informative keep up the good work

Thank you very much for this video! It's very informative, and helped me a lot understanding how NPN transistors work, even in english which isn't my native language! :) Thanks again!

Good stuff ! Thank you for this.

Thank you, could you please do other videos regarding use as an amplifier and also for a pnp?

this is awesome!!!! simple very clear...

U are good, hope all is well

Thanks for the video michael! Thanks for contributing

Generally the resistor that you should use for an LED is that which would result in the current passing through the LED to be 15mA. So if you're using a 5v battery, and the LED drops the voltage by 2v down to 3v over the resistor, then in order to get 15mA you'll need 3v/0.015mA = 200Ohm. It's good to know so don't forget that ;-).

thanx....best information about transistor

very instructive video

thanks a lot! as a starter in electronics this was really helpfull. thnx!
