I legit have never learned a thing about reading circuit diagrams and that circuit diagram is what helped me understand how this works with real electronics and not just a logic gate simulation. Thanks a ton
Wow, looking at the circuit it appears to be a symmetrical configuration being the foundation building block. Looks like a astable multivibrator as it lacks capacitors. So when the power turns on and no button pressed yet, which side conducts first?? Would that sided be consistent every time?
well it appears symmetrical, but don't let that fool you. These components are never 100% identical. I haven't tested it and am not an expert but I would guess it would always pick one side.
@@TheFreak111 That is correct. Between doping of the transistor and discrete resistor value differential tends towards saturation, thereby, impact which side is favoured. Circuit modification would "force" an output to ensure specific outcome at power up.
@@TrillShatner By gate, you refer to the pushbutton? Being fully off, you refer to the LED being off? I therefore disagree as by nature of the design it will try to drive one side on at power up. The base resistor of one side connects to the collector of the opposite side disabling forward bias (same as pressing button to short base to ground)
An interesting and instructive video. At last I understand how a flip flop works. But I wish you had shown what would happen if you pushed the same button twice in a row. As I read your circuit, it would not change state. Is that right ? I guess that is why switch bounce is not an issue.
i'm a 9th grader and i'm watching this for the sake of passing our exams tomorrow (we have a special subject for these engineering and techy stuffs... -.-)
I agree that both sides are symmetrically equal in operation, but not sold on the speed if identical valued transistors used. Yes, doping determines the characteristics of any transistor and its application. OK, identical transistor is a lose term unless paired. Realistically, it is the minor doping that determines the race to conduction with consideration to actual resistor values in this circuit which can be controlled to favour a desired state as required by external components.
Not too critical. You just need to "saturate" the transistor, which means get it out of the linear region. 10k is usually sufficient to the base depending on voltage and the type of transistor involved. The transistor might get warm if the current draw is big enough otherwise. 6.8k is much lower than required, but is still a safe value for the base without drawing too much base current. Think of a clutch in a car. You want the pedal all the way up or all the way down or it overheats.
Well explained. Can you explain a situation where if 1 LED (LED1) gets 5V supply (continuously) the 2nd LED (LED2) switches off. But when LED1 does not get a 5V supply the LED2 should switch on. How to do this? Please explain with a circuit diagram.
@CyberNaut : technically, you can't press them at the exact same time. One will be pressed after the other. And even if you wire the two transistors to the same button, the shortest wire will win.
Yes, pressing both at the same time does present issues - agreed. Cannot bridge both transistor base to one button as will defeat flip-flop as both sides will conduct together. So what is the resistivity of the wire use discussed to impact operation??? Having sound knowledge of flip-flops you would understand where I was going with it.
so like, can't you people make a... a.. thing which can send the input signal at the same time, instead of notoriously pushing both buttons at the same time?
Yes, EEPROM (Electrically Erasable Programmable Read-Only Memory) as the binary value remains after power is removed unlike the circuit above. After all, the humble flip-flop is the foundation, is it not?
A Latch or Flip-Flop being same thing as employs a "set" and "reset" sequence like a stop-start station for motors. Back to topic, No - not a NOR latch being simply two inverter's, but can employ NOR gate or Nand gate to create Flip Flop. Using more stages create a "J-K Flip Flop" to move to "D Flip Flop" to move into counters and shift registers
Its original name is Latch circuit which first introduced by british scientist W H Eccles and F W Jordan in 1919 where the electrical state of the output was reversed when an electricals signal was applied to one of its inputs . However in 1940 , the latch circuit came to be known as the flip flop circuit because of the way the output signal flips or flops with each pulse it received.
Regarding the ubiquitous Trump comment found in literally every video, no matter how unrelated to politics; Here's my take. This is not the True Trump circuit, as it requires too much user interaction. Also, once a switch has been pressed, the circuit tends to stick with it's "choice", something Trump would obviously never do. edit:READ MORE CLICK IT DAMMIT I say, remove the switches, put the center resistors where the switches were, and put some capacitors where the resistors were, and THEN you got yourself a trump circuit.. It flips all the time, based on the relation between the swapped resistors and the capacitance. And it's calle an astable multivibrator, so you can all have your chance to get your joke in now. Suck it, Guy De Vos.

loved the education at the end of the original transistor!
i am neither a science student nor a hardware student.
just a programmer who wants to know his computer better...
going down the rabbit hole.
Great.. I also came here like you

I would think with none of the gates closed it would be fully off at first.

Beautifully explained! Thank you very much for this great circuit.

Yes that is right
Actually you dont need the two base resistors if the collector resistors are big enough to protect the base from too much current.

Fantastic video, clear and concise, thanks a lot!
What is the default state when the circuit is powered initially?
Both sides are equal in theory but minimal.differences in the speed of the transistors favor one or the other
I agree that both sides are symmetrically equal in operation, but not sold on the speed if identical valued transistors used. Yes, doping determines the characteristics of any transistor and its application. OK, identical transistor is a lose term unless paired. Realistically, it is the minor doping that determines the race to conduction with consideration to actual resistor values in this circuit which can be controlled to favour a desired state as required by external components.
What prevents the leds to initially turn on both, won’t the current open both gates simultaneously?
THANK YOU FOR THIS AMAZING VIDEO
I first used a 2N2222A116 transistor and the circuit didn't work. But when i used a BC337-40 transistor, it finally worked. Why is that?
Will you please suggest a circuit to use two 9 watt 220 volt LED bulbs in the flip flop circuit uit
You earned a sub.
did you used ac power or dc power 12volt?????
A really nice explanation! Could you share how you calculated the required resistance values?
Not too critical. You just need to "saturate" the transistor, which means get it out of the linear region. 10k is usually sufficient to the base depending on voltage and the type of transistor involved.

Nice video
If the circuit is on 2, and you put the power off, would it go to 1 when you turn it back on the power/electricity?
gonna make a coil gun with this
Hi, nice film and pretty good explained. Thank you. bye Toni
pls I'm asking if you can help me with the transistor circuit diagram of an SR latch using two NOR gates
Well explained.
Can you explain a situation where if 1 LED (LED1) gets 5V supply (continuously) the 2nd LED (LED2) switches off. But when LED1 does not get a 5V supply the LED2 should switch on. How to do this? Please explain with a circuit diagram.

Nicely explain 💚
Pretty good explained, Thank you
Great video and as always really helpful thank you 🏴
are you using PNP transistors or NPN transistors
Can it be made automatic without the push buttons
Now what will happen if the same button was pushed twice...?
Second push does not chamge state
Ludic Science Thanks, and also for replying..., not very much people answer back the comments...
thanks very much!!
can you make this with mosfet transistor
Nice and amazing bro
no eres el de electronica practica paso a paso?
What if you press down the two buttons at the same time ?
Nothing happens second time
What if both buttons press together and release together - can we predict which transistor turns on??
@CyberNaut : technically, you can't press them at the exact same time. One will be pressed after the other. And even if you wire the two transistors to the same button, the shortest wire will win.

thankyou
If we put capicter here it bekm automatic?
friend, please look at my diagram ruclips.net/video/sb7-gBqXJtk/видео.html
Great vid.
I is on 0 is off? So the one is on,than you sens that one over to other side than the off is 0?
Does that mean that for storing a bit, do we have to constantly power it?
In this case - yes to maintain the binary state as not EEPROM :)
CyberNaut WA EEPROM?
Yes, EEPROM (Electrically Erasable Programmable Read-Only Memory) as the binary value remains after power is removed unlike the circuit above. After all, the humble flip-flop is the foundation, is it not?
CyberNaut WA True buddy! Thnx ;)
What about the small red wire ?!!
please make a arc lighter and the hand wound high voltage transformer
Also great vid👍
Tu eres de "Electrónica Practica" a mi no me engañas 😛😁👍
It's also called a Trump circuit...
😂😂😂
Wait, doesn't that apply to most politicians though?
But how much the speed of the trasistors
Check data sheet :)
CyberNaut WA thank that was helpful
Ad a super cap powerbank project

Good
i feel kinda jealous.
Like nice video and nice explain 🤔
Sir make it 3 phase plz
This is sr latch circuit but u said this is flipflop circuit if u apply trigger then it becomes flipflop please xplain

@@MrProgrammerX tq i have done the same project for my btech 2nd year it works nice
But give me small clarity about connections are u grounded emitter or collector
Small confusion plz
i prefer the 555 and 556 timers for all my flip flopping needs.
Transistors are cool if the circuit is configured to run on full auto...
Cool, analogue over digital control :)
It's nice, but the circuit is actually a latch. Flip-flops are clocked.
The circuit clearly is not.
Hi sir request wiring tool direct coil with rpm &frequncy
