FLIP FLOP LED Flasher Circuit Using Transistor BC547 (Breadboard Tutorial)

[@rejithnair4754]

Hi.. Thanks for the circuit.. It's really great circuit.. In the video you told connecting two emmiters of the transistors and you actually connected the emitter with collector of the second transistor.

[@IdeasTv]

Yes there's a mistake in caption 3:06 . connect Emitter with Collector. comment pinned.

[@frederickbrown9631]

Cap

[@checkerface5710]

to be honest 3:06 to 5:58 are all wrong to be honest (the first capacitor connected to collector ) when it is connected to emitter.

[@clicksandbeeps61]

I cannot follow it’s so confusing. Which is the 2nd transistor? All of the video from 3:06 is wrong :(

You said connect both emmiters and you connected the emitter to the collector of the second transistor that's why mine does not work. Now is this do as I do or do as I say?

If you take note of where the connections are or go, and ignore the captions which tell or give the wrong information, you should be able to get it to work as I have.

[@chudionuigbo5952]

Nice tune! Where did you get it from?

[@PrajeshNSG]

Would this work if I use a 220 k instead of 470 ????

[@richardl6751]

The 470 ohm resistor is to limit LED current. 220,000 ohms might be too much.

[@KaustavMajumder]

3:38 - Are you connecting to the Transistor Collector or Emitter? Is it just me or are you referencing collector as emitter and vise versa? The order from left to right of a BC547 NPN Transistor is Collector, Base, Emitter considering the flat side is facing you. If I'm wrong then please correct me.

[@IdeasTv]

[@sphynxink]

I'd be lying if I said I didn't nearly cry when I got this to work. Time to figure out how to string a whole whack of these instead of just two

[@NotAnotherFucking]

Dude you’re crazy you might as well make a microprocessor instead. You could wire billions of these togethers and you’d have a real microprocessor with real programmable computer logic but you’d need an understanding of registry’s, memory, etc. By then what would be the point. Just use a CAD program and design a chip and check out Sam Zoloof’s channel for photolithography.

[@sphynxink]

Lol when I did this two years ago, this was the first time I’d ever even seen a breadboard. I don’t know if I even know what a microprocessor was 😂 It was for an assignment I had in college. But good to know!

[@hectordionisio7303]

im confused when you connect both emitter but each of them are in the opposite side of the transistor?

[@Compuscience-Python-Prog-Exps]

My capacitors are too small. They are tiny compared to yours here. Only one led blinks really fast; the other just stays on. I need the ones you are using. Drag.

[@IdeasTv]

select capacitors by value, not by size

[@Compuscience-Python-Prog-Exps]

@@IdeasTv Hi, I've been into computer programming, since I ever knew what a computer was, but now, I'm a much older man, and I'm doing Breadboard Electronics with the Raspberry Pi and Python programming with it. You're video showed me how capacitors work, in conjunction with the Two Transistors. You explained it perfect. My two capacitors were very small in size, but the same style yours were, but ten times smaller. Only one light would blink very fast, because of the natural timing of the capacitor dumping back into the other light, so it couldn't blink at all, because even yours had a bit of a difference in the back and forth blinks of the two lights, one blinked a bit faster than the other, when viewing them going back and forth. But you taught me what the capacitors do, and I had also learned that transistors block out noise, like a switch. I don't have enough of them to make my 24 bit binary Led dance, so I'm going to see noise from the other LEDs, but I'm going to show beginner Pi users how to create a Binary Beat program with Python and a Breadboard with lots of whatever colour LEDS one wants to use tok go right nuts on the RPi 4 with me. Check out some of my videos on it, I show all my progress on how I learned to make things with it and show others, how it's not that hard to learn. I'm teaching it, while I'm still learning it myself. I've only been into it for about 7 months now. I have much to learn with electronics in full general, I'm not anywhere close to your Genius yet, but I'm 57, I've been soaking the RPi up pretty heavy though. Please take a look at my latest video on Fun with three 74HC595 shift registers. I learned everything from you BRIGHT PEOPLE. Everything is from you guys helping us all. YOU!!!! xox Thank YOU xox
