- Updated! Derek has this overview of Flip Flops and how they work: • How Flip-Flops Work - ...
Which explanation do you like better? Let us know in the comments.
In the last lesson episode ( • How Flip Flops Work - ... ), Karen explored SR and JK flip flops. In this episode, Karen uses an SR Flip Flop with Preset and Clear to demonstrate how the inputs affect the outputs. Using that circuit and no additional parts, Karen shows how to use that flip flop to create a toggle circuit. The final project shows how the circuit can be used to create a Yes/No, Either/Or sign. This circuit is just the beginning. Adding a 555 timer or sensors instead of a button opens the door to the many different ways this circuit can be useful in an everyday item: bit.ly/2N8o56e

74LS series chips are classic TTL and don't strictly need pull up or down resistors, as they basically have them built in. CMOS variants like 74HC are sensitive to electric fields which can cause erratic behaviour or result in increased power consumption if pull ups/downs aren't used.
Still it's always good practice to pull unused input pins up or down.
Good trick with self clocking. Thanks.
By the way, if you tile video with IC Name, then you'll get more viewers who are interested exactly in this chip, not only subscribers who are watching all your videos. :)
5:33 - did you forget on schematic connecting Data pin 2 to PIN 6?
Sure did! I went back and worked on the graphics for this one a few months after it was shot, so the project wasn't super fresh. Must have missed it. Nice catch!
Your tutorials are very interesting to learn...never stop,go ahead😍
Nice work....well I can make a stop watch through this ...or an auto heat soldering machine
I love this video, keep up the good work guys!!!
Hi love the video can't wait for the 555 timer to be added hope it's soon , All the Best Brian 🤗 Thank
555 timers are next! And there will be 2 lessons and 2 projects about 555s! Double the usual fun, and learning!
@@maker_karen1785 Don't forget opAmps, ADC, DAC, digital POTs, etc.. Logic can be done by microcontrollers, but analog ICs, does what MCUs can't. For hobby usually you're the author of circuit, and it is more likely that you'll get back to your project with upgrades, what can be easily done with MCU. If you use logic gate ICs, technically for any upgrade you need build new PCB setup. I would say today Logic gates are fun, but for hobby has not much use except educational purpose. In production it can save price per IC, but for hobby it doesn't matter. Just saying what I think, but I like your videos anyway, even if it will be about 555 timer :)
Chain a few flip flops together to make a counter or shift registers, then explain some possible uses for them.
Will you consider doing some sound projects? But made with discrete IC’s..?
Thanks. Very excellent channel.
I’d like to request more circuit projects with discrete IC’s. Especially CMOS.
Have tried to build a radio around a 74AC74 and 74HC152 and 2x MC1350 chips which drive a phasing combiner which then drive a speaker via amplifier. if you don't understand what I mean it is a Quadrature Sampling Detector.
Interesting, although a momentary toggle switch with Centre off would be less complicated!!
Help, please, how can I get a screen to show the data, preset and clear …
Here's another video explaining Flip Flops: th-cam.com/video/S28QFe7EdNI/w-d-xo.html
Which explanation do you like better? Let us know in the comments.
for the single switch toggle you omitted the D to /Q from the schematic,also not much in the way of contact de-bounce,D type not SR.
But still a good presentation.
I have a question, every time you power ON the circuit, the output Q will start being HIGH?
yeah yeah nice question , I too need answer for this question
Nice
The 7474N is not an SR Flip Flop, it's a Data Flip Flop (type D)
So you get high quality content, high quality cameras and aaaaand a crappy power supply.
Just use a relay. Or a toggle switch.
It's the journey, not the destination.
@@haku-jin you can get the journey from the simple way too.
@@azimalif266 It's a tutorial on using an SR flip-flop in a simple circuit, not a tutorial on how to wire up a toggle switch to light a lamp. They're completely different journeys and one has many more destinations branching off it than the other.
@@haku-jin add an arduino to a relay.
@@azimalif266 Okay.
