this is one of the best explanations of the inner workings of the 555 timer that I have seen in a long time!

i used them a lot but never looked closely opn how they work, very informative, thx Karen!

Great job Karen! Wonderful job explaining. You are getting very good at quality examples and the discussion of complex items.

This is one of the best presentations for working of the 555. We've used the 556 as astable and monostable together to produce a PWM signal for a Boost Converter, 12v t0 48v DC at St. Joseph's Research, BLR, IN.

First time I've seen an understandable description of this chip. Thank you. By the way, I have a friend who says he's bistable, but practicing as monostable because it's just easier to live that way. All good wishes!

I have seen so many videos about 555 in my native language but somehow they were confusing until i found this video simple and understandable even with a foreign language description

Nice presentation, Karen and thank you for the information on the internal operation of the 555 engine.

I’ve watched four different explanations on the NE555 internal workings and so far this one has made the most sense. A bit fast in places but it’s a video, I can go back and watch it again and try to pick up what I’ve missed. Thank you so much for your time and expertise on the subject matter and for “dumbing it down” in plain words and diagrams so that more people can enjoy electronics.

A good 50 years ago I started in electronics making my first medium wave receiver with an ECC82 valve. A year or two later, in 1972 the 555 was introduced and I've been dabbling with it ever since. Thank you Hans Camenzind ! Nice video BTW 👍.

Fantastic job done! Well defined and explained. She is great!

[davidcross]

Awesome thanks. Very well presented and I’m looking forward to learning more now!!

Very nice tutorial, especially given it can be configured 3 major ways. I am a math guy that hobbies in electronics and studied the 555 a few months back. It was nice that your video mentioned that the integrated flip flop actually used only one of the outputs which is a detail that often is overlooked in other explanations. I ended up building an astable Multivibrator so that I could put out a weak signal in the AM broadcast band spectrum in order to test reception capacity on regenerative radio receivers that I assemble from parts at hand. It worked, barely. By barely I mean that high a frequency was kind of pushing my luck. Without filters it was also broadcasting everywhere much like a skipping stone across a pond.

A little bit fast in places, but a very useful video nevertheless. It certainly helps to demystify what's going on in the chip.

Thank you so much for helping me figure this out!!!! It took me a long time to conceptualize how ICs work

[IFixOldStuff]

Great work here showing how the basic building blocks become more complex circuits

[armincal]

I'm by no means an expert in electronics yet the way you explained it was so good that even I understood everything.you deserve a sub

What an amazing video explaining the workings of the 555 ... So well explained .. Gave me a far better understanding of it, and how to use it, in all 3 forms ... Excellent video .. I also checked out the 2nd video you did as well .. Regards, - Anthony

[spudnickuk]

This has got to be the best video i have seen that explains how to use a 555 chip with proper illustrations of how it works

[sinewave]

Thnx a million for you're videos! I really appreciate them! Alot! 😎

I've never seen a high quality explanation like that. Congrat!
