Finally, a presentation format I understand. Thank you.
Put the fear of God into heart
Great
hi everyone ,if anyone else wants to discover introduction to electronics courses try Letza Easy Electronics Lessons (do a google search ) ? Ive heard some unbelievable things about it and my m8 got great results with it.
Incredible! One of the best overall explanations to logic and chips. I can't believe you packed it into 13 minutes.
I got struck onto this for many weeks and I had no idea what's going on . But , joining onto this channel really gave me a Clear understanding what's been really going on .
This is what we need to really learn. Probably the Best Tutorial I've ever watched! WOW WOW WOW!
Holy crap, you managed to explain this concept miles better than my professor! Thank you so much!!
VERY well done and clearly explained for laymen, on a fairly complex subject. Thank you for your efforts.
Thanks for this helpful video. I understand it better now than when my professor explained it.
Passed my midterm thanks to this!
I never saw this video before, but This was soo much better than any other video and self study I did before. I have done in Ece322 introduction to logic gate, but this one sure is the most comprehensive video I have Watched thank you!
I love the epic intro and then something extremely nerdy xD love this explanation!
This helps a lot! Big thanks to you guys!
Finally, a very easy to understand video for beginners
Thaaaank you soo much you helped me doing my universty homework 😊😃
Dude, subscribing for the intro alone. Shits dope.
Excellent visual presentation!
When I was messing around on a logic simulator app on my phone I found something interesting. if you ignore something called gate propagation delay, and you connect the output of the not gate back to its input, you get an infinitely fast square wave, as if you feed the output of an inverter back to its input you get an infinite recursion.
Wow, great animation and best knowledge
helped a lot(in correct time)
thanks...
Thanks a lot! I've been waiting for a tutorial of this sort...
Wow, this was an excellent presentation. Thank you!
so fu***** helpful, I can't even! I love the experiment part shows exactly how I can use them in my project thanks!! thumbs way up!!
If you're a noobie, it takes about 15 mins. to understand, which is great! :)
Thanks for this.
Very detail the actual demo of how to make it is especially helpful,
it helped a lot as missed my college practicals ...!!!😉
Most excellent tutorial. Thank you.
I have spent months researching into circuits and found a fantastic website at Gregs Electro Blog (google it if you're interested)
Great demonstration, I indeed understood it, I appreciated it. Thanks 😎✌️
hi guys, the best results that i've had was by using the Gregs Electro Blog (i found it on google) definately the most useful info i've followed.
Well explained!
Its really a useful and very good video. Thanks
Most excellent tutorial. Thank you
8:43 - WRONG: the two left LEDs are connected directly with the power source, there is no interference of the IC.
Comprehensive excellent explanation , Thank you Professor :)
Very well explained, thank you!
thax..this video is very helpful n easily explain..to form all basic gates
Is there microprocessor videos? Or micro controller is the same ? I going to major in EE and i have learned this and I'm moving on to microprocessor and more but I wants get a head start so i won't struggle in class. The video is great and it refresh my memories a lots. Thanks
Can I buy this kit with all the components your using in this video together or do they have to purchased separately. I’m very green to this and want to get a head start before we are doing this in school? Thanks for the video 😎
Great stuff. I'm doing course on this without a maths background, we had the intro to Boolean logic today and our first labs tomorrow morning! This has helped clarify the connection between logical and circuitry and helped prepare me :) thanks!
What is the difference between pull-up and pull-down resistors again?
pull-up resistor creates high voltage if there's no other voltage source connected, pull-down resistor creates low voltage (ground) in the same case
Brilliant tutorial, thanks !!!
This helped a lot for trouble shooting
In general, is it a good idea to use HC family for similar circuits with LEDs? The specs are saying "±4 mA Output Drive at 5V".
how to provide electricity for each ELD independently in this circuit?
I have a 7905 regulator instead of 7805 i.e. a -5v regulator. Can I just replace grnd by this regulator and give the grnd connection to the +5v pin of IC? In that way the +5v pin will still have a higher voltage.
Nice explanation!
Omg i actually understand it now...very good tutorial.
Thanks for your video, i really like it. i tried to set up the not gate, when the input is zero, the light is on, but when the input is one, the light is still on but a lot dimmer, not off. Is there anything wrong with the gate ? i only used 5 V, pls help. Million thanks!
how could i know if the ic is AND gate or not?
Very nice video for study....
How are you getting the lights to turn on to see if the logic gate is correct?
how is the input and output changed?
Very good tutorial learnt alot
how do you switch on/off the led's ? how come all three leds are connected to ground for the and gate ?
Very Helpful Video Sir,
Thank You!
I always say it and gotta say it again, that intro is damn mad
Would you show the calculations for current and voltage?
i set the circuit up identically, but i always seem to get zero as an output, regardless if the input is high or low
Jesus bless you for helping out. Amazing explanation
This is really fantastic!
easy to understand, thank you!!!!
Really superb man
Could you show how to build these gates using transistors instead of IC´s?
very well explained
Make some also basic practical video like this with breadboard 😊
Best tutorial thanks i understood everything
They teach us in Australia that X and Y would be represented as X ∧ Y
Which software you will use in drawing schematics diagram of circuit.
please reply sir
BRO..USE "MULTI SIM"...which was useful for connections
Why you don';t need a pull down resistor for the inputs? If I don't use a
pulldown resistor for the inputs, the output has unexpected results.
Thank you.
Hey everyone, the greatest results that ive had was by following the Gregs Electro Blog (just google it) definately the most helpful course i've tried.
Thanks from Swedan.
Thank u sooooooooooooooo much for this explanation
Can you make a video on schmitt triggers & flip flops please
What is a bus line? 6:50
What is "not" 1+1= 1 implying , over current ot voltage is reducing current power / watt and increasing heat? Stall not gates from compu of mine
simple and effective...thanks
thanks a lot for uploading this amazing video....
So how can you tell the difference between an AND, OR, or NOT chip just by looking at it?
Are you supposed to remember it by its number?
Yikes!
A *simple solution* would be that the manufacturers write "AND", "OR", or "NOT" on the circuit to make it clear what it does without the need to memorize a table or series of circuit numbers. :)
An *improvized solution* would be me sticking tape on the circuit and labelling it myself. :D
Don't mind me. This is a personal pet-peeve of mine lol.
That would be a solution if only a few types of those IC exist, but the coding is needed as we have a LOT of different chips
I can imagine. Too bad they didn't implement the word "AND", "OR", or "NOT" into the ID.
Instead of calling it a "7402", they could call it an "AND-7402".
That way you know what it is at a glance, and then the number tells you what type of AND chip it is, so the number could actually be shortened. :D
thank you very much i understood many things
QUESTION! Why do we need the resistors as part of the circuit? I don't think you talked much on those?
To stable the electricity or the current in the circuit
very excellent video.thank u sir...
If the 7805 regulator is only for 5v, why does it have a heatsink mounting hole?
Because of the 7805's low efficiency, if you are regulating 9v to 5v at 100 mA, the power lost is 400 mW, which is a LOT
Really useful thanks man
Wow now I understand, thank you
So 1+1=1 means two ways electric current charged of same watt ?
Еasily and clearly.
Where can i buy
Why is the regulator necessary? Why not use a resistor to drop the 9v to 5v?
Well, only a single resistor can not create a voltage drop. So for that purpose we'll need a resistive voltage divider. But there is some problem. As other components in the circuit have their own resistance they also work as loads which ultimately creates a different voltage than we need. A 5V zener diode could be used but it may not handle huge loads or cannot supply sufficient current as a series resistor must be used before the zener, which will limit the current. Whereas using a simple linear voltage regulator makes everything simple, it can even handle upto approx 1.5 Amps of current.
awesome video
Neat presentation
Really helpful
Sorry for the question spam, but 1+1=2 (base ten), or 10 (base 2) not 1. How does that work with the OR gate?
+Matthew Ferrie I had the same question when I watched this just now, but I think i understand why: There is only bit. (base 2:) 01+01=10 because there is room to store both bits. but with only 1 bit, 1+1=1.
Actually, this is a good intro into how a finite number of bits causes imprecision in computing. If your interested, look up floating point representation, machine epsilon, rounding error, or simply floating point imprecision.
+iamtweety90 Interesting! Thanks.
Thank you
Amazing video
very good explan...
I have some ICs but none of them have a notch at the top corner. They have notches, but they're in the top center. And none of them have that exact string of numbers yours has. Are they supposed to? I don't know how to tell these ICs apart.
If you are looking at the IC from above and the notch is on the left hand side, pin 1 will be below the notch. For more reference do a google image search of 'standard ic pinout' and you will find other pictures people have taken with the center notch and the pin numbers labeled. As for the numbers. All you really need to find on the IC is the 74 and the 00/02/37 or whichever you are looking for. All manufacturers label theirs differently, but those two numbers will be on all chips.
The only notch is on the top center. It's not on a left or right hand side, but in the center.
en.wikipedia.org/wiki/Pinout Yes, that's normal. Please check that link, it should clear up your question.
PyroElectro Alright, thanks.
PyroElectro thanks bro, your lessons are really helpful !
my output(led) always turn on when im moving or switching my inputs to high/low . it will only close when 1 or both of my inputs are on ground help
Aye fellow dota2 player! these vids should help you lol. I had the same problem.
