Dude, this course is helping me through my engineering PhD. I'm a chemical engineering but now utilising electronics. Thanks you :D
I've been cruising through this series, and just wanted to thank you for doing these - you've done a fine job of breaking down electronics into simple "building blocks" for beginners. But even for those of us who have experience in electronic repairs, it's kind of nice to go through as a refresher or reinforcement of concepts. Specifically for me, I went from doing repairs into management about 25 years ago and haven't had to personally touch electronics for much of that time. I recently decided to start "tinkering" again and have a goal of getting back into the repair side both as a hobby and supplemental income. I'm frankly surprised at how much I've "forgotten" and need to be reminded of, and your tutorials have been just what I needed to "trigger" my memory. Some of the more advanced videos I've been watching up until now had me feeling intimidated or ashamed at how much I "don't know anymore", but your videos are giving me back my confidence and empowering me. Thanks again!!
so happy to see you back in action!!
I really enjoy it a lot when you include the visual practical work. It really helps me to concentrate and remember easily. I do say that you create one of the best educational videos on TH-cam and I find them really enjoyable to watch them :)
Thank you so much for this amazing series! I can't wait for the next episodes! 😀
So glad you are doing the videos again, all the other tutors seem to have patches on their jackets and send me to sleep!
i am glad that you come back on line mate ,
looking forward to follow you mate
so far, you sir had my upvote for best electronics for beginners tutorial series. Can't wait to watch the next one (transistors!!!)
I'm glad you like them, thanks for the support!
Really to see you back: I am retired and getting into electronics I have a couple of books and am following a couple of on-line tutorials - yours is by far the clearest (in my opinion) I was sad when I finished #20 and found no more - delighted to find #21 yesterday - Thanks!!!!
Glad you are enjoying them! More to come soon!
Glad to see your active again! Your channel has gotten me into electronics as a hobby. Thank you.
Glad you like them, thanks for the support!
Very glad to see that these are back!
LOVE this series!!! Thank you!
Thanks for posting this installment in this series.
Excellent simple description of the capacotor
As usual a great educational video. Thanks so much. I'm learning a lot.
This is the best relay explanation. Initially I thought these are not useful as much, but judging by your explanation they can be super useful for controlling a single circuit via another circuit / power source that can have its own separate logic and can be distant. This kinda expands the list of tools you can use while designing your circuits in other words uses your imagination :)
Nc you're updating again XD can't wait to see more of your videos!
i love this series! plz keep it up man
I love ur channel. It's extremely fabulous. Ur explanation is fantastic. May god bless u a more more knowledge that u can share with us.keep it up.
This is amazing thank you SO MUCH; the only video that made me properly understand relays.
Loved the series (get it: 🤔🙄) watched it all in one day. Eager for the next!
thanks for making this series man this is awsm... i m learning a lot now
Thanks for all the help
thank you so much for giving a good lesson in Electronics...
Luv it!! you tutoring is patient and simple. However, your breadboard arrangement relates to electron flow and not conventional positive to negative ?
we are waiting for ur next 22nd class video. it will be a glad if u upload as soon as possible.
thanks for the video looking forward to future videos
Vehicles have relays with the ignition switch (used to be a push button on older cars,) . When the ignition key turns on, it supplies power from the battery to the vehicle elements. When the key or push-button is activated, this sends the charge to the relay some on the inner side of the fender, to make the electromagnets live and connect the contacts to supply the power to the starter. This then activates the starter, UNTIL, the key or push-button is released.
Kept up so far. Not too too complicated, thanks.
Sir make more video in this series
This are very very useful
I am making my own circuit
Thanks for this
*Summary:*
- a relay is an electronically operated switch
- instead of a human flipping the switch, we have it so that electrical flow closes the switch ("think long range switch")
- relays also have limits, so be sure to read the data sheet!
Thanks, I've always been confused but also fascinated by them. Explained perfectly
We are waiting anxiously for the next episode of the java game! :D
Are you doing a video about inductors?
cant wait for more videos
Bro greetings from Germany you are awesome!
Nice work.. provide good knowledge
If you are making this or not, please do videos on ICs, transistors, and more that you can find, but just if you have time. thnx
don't wait a year to make another video :(
Don't worry, every Wednesday morning (and occasional Saturday nights) there is a video planned, and hopefully it will stay that way!
CodeNMore Please be as early as you can
Jesus did your voice drop since the last video
The camera cannot see, although you did say, the negative terminal on the switch side of the relay is connected to the negative rail on the breadboard.
Hi i dont get it on the dpdt relay lets named the lead 1 2 3 4 starting from the right one as the first ( the electromagnet)
So the 2 and 3 are normally connected when no current. When there are current 3 and 4 are connected is that right ? Or when there is current 2 and 4 are connect ?
The pointing make it hard to see. I wonder when the electromagnet is on it should attracted the switch to be on its side but why 2 and 4 are connected then?
The hardest part is number 1 ( the first pole is connected to the capacitor ) but the 2 ,3 and 4 how do i know which one to connect to ? In the video the resistor is connected to the second one and the 4 is connected to negative. Why is it has to be like that can we connect it to number 3 instead ? Or swap 2 and 4 .
Thank you and thank you so much
I really wanna know the answer.
And the video 23 confused too !
I will leave comment at the end so you can quickly find .
Thank you again
wheres the rest of the videos bro?? these have been some of the most helpful videos for gettting into electronics. weve gotten past all the basic boring stuff come back plz. i wanna see more fun circuts to build and i wanna fol,ow to the end goal of this 8bit pc!! plz dont give up on this series man!!
They will be coming, at least 1 video a week. Better consistent than waiting 4 months between videos!
Hell yea. I'm loving them. I took a computer / electronics Tech at the local votech back in school around 2010 and just recently got back into soldering and working with circuts and shit so I know alot of the basics was just rusty. These videos been a great refresher and I'm ready for some more hands on circut building etc. Thanks for the reply
Nice video thank you!
Hey I have doubt that, the resistor is to be connect on either ends of the load , or... But in these vedio you showed two of them is it possible ??....
Please give the reply
I understand now. It also goes to the negative of the battery in order to also give power to the led.
what's the black wire on the far left of the circuit connected to?
second, I would like the next java video game tut video :D
Best tut on relays. Just started with relays myself. I just dont get the second ground wire in the circuit. Does anybody know? Im bad with circuits, damn!
Where is the best place to buy all of these components ?
Hi, and thank you for your great videos ! I have just one question.
You pointed out that a relay does work independently without human interaction, i.e pushing a button.
How do you hook up the relay to actually do that, for example an indicator on a car?
it's done by another circuit (a logic circuit, or programmable circuit )
@@truthseeker5796 Thank you. That makes sense.
trying to find part! yours says its a "HK19F" which is rather expensive at $8,50 an "HK4100F" is $3.50 the 19 does match what you have and the 4100 simply says its a mini power relay. what does the "hk19f" mean? whats the difference between the two?
So wants the point in having a relay if youre going to use a button ? And vice versa ?
I don't know if you're still making these videos, but I have a question: The relay you are using says 2A 30V, but you are only using 9V. Does it matter that the voltage is less than the relay's rating? I read somewhere else that if the voltage is lower it won't power the relay. Great vids, I'm working my way through them building as I go. Thanks.
It is the highest voltage rating for relay it mean it can't handle for than 2A and 30v (AC or DC it have been written)
@@rekhasaini672 that does not answer the question...
Are relays just inductors?
So if I have a regular magnet aside a relay... will it screw it up??!?
if it is powerful, yes
come on waiting for episode 22
Best on relay
What source did you use to get 5 Volts. Are you combining batteries of different volts?
The output of the switch is only five volts
It says so on top of the relay.
And do you still make videos
Did anyone notice that the electricity flow from the negative terminal of the battery (or the generator)?
I want to meet you where do You live bro
what is that ground wire for?
The ground wire completes the circuit , off camera it is plugged into the ground rail on the switch side of the circuit.
why is the resistor connected to the cathode of the led, isn’t suppose to be on the anode side? how is even possible that the led light it up!? Tesla magik !!!
are you a dumbass it works either way
When is next new beginner 2D java episode?
February 15th, 8:00 AM EST it'll be out ;)
When would you use a relay rather than a normal switch? Electronics dummy here!
can you make other videos fast please.
Unfortunately my uploads will not be very fast...I would much rather them be consistent rather than me stop making videos for 4 months again. But you can expect videos to come at least once a week now!
+CodeNMore Thanks
+CodeNMore Thanks
If I wasn't wacthing your videos all at once (marathon) your explanation of the current flow through the diods would be really confusing!
honestly... I expected the LED to be connected to the negative lead and not the positive lead... Now my head feels scrambled. lol.
first to watch this vid
sounds a lot like a solenoid
I dont get the point of the relay. Cant you just make this with just the button?
Yes but a person doesn’t have to use it and electricity does it all. Also i don’t know much about eletronics but I believe this can be used as a timer. And it can hold the charge until it loses it’s charge or is halted.
Give us a Java Tutorial! I want to know how to add music to my game! (plus sound effects if you don't mind.)
Like if you agree.
Next Wednesday there will be one!
THANK YOU! I can't wait!
Me too!!
hehe 3:40
Exactly my doubt
second
Why do you say "to" twice every time you say it? Lol
Does he? Where?
why bother using a relay, why not just use a swith. did i miss something?
