Introduction to 555 Timers | Basic Circuits
HTML-код
- Опубликовано: 22 май 2024
- 555 timers are an incredibly popular IC that is useful for timers, switches, LED blinking, and more, using a simple analog circuit and no programming. In this introduction to 555 timers, we discuss the pinout and review the internal circuitry and logic, which both gives it its name and drives its behavior. We explain the different 555 timer configurations, such as the monostable, bistable, and astable configurations though we get into more depth on those particular circuits in later tutorials.
This video tutorial is based on the written tutorial that Jayesh created, so go check out the written portion that Jayesh did here: www.circuitbread.com/tutorial...

This is a very, very valuable lesson. Thank you eternally for sharing
Excellent explanation. Looking forward to the next few tutorials.
Good morning "toaster guy". I am happy to see you have a video on this subject. I really enjoy your videos! With toast and coffee of course.
Great explanation. Well done.
Love your videos!
excellent ty
Nice...cheers.
Very very good sir
Usually SR/RS latches have a priority by design. So SR would be set priority, RS would be reset priority. I don't know if any priority is codified for the 555 or if all manufacturers cook their own stew here. But it should be consistent at least within batches.
Maybe i dig around in my chip collection and whip up a bistable circuit. IIRC i should have at least chips by 3 different manufacturers.
I think it with worth exploring since the 555 is an easy to use flipflop for example in power on reset circuits, or as part of an interlock.
This will be a great thing to comment on and discuss once the bistable video is up as well, as I did a terrible (non-existent) job of explaining where you'd want to use a bistable 555 configuration. 😬
So well explained that even me a third world Neadertal can understand.
