    This has been a lot more than an explanation of the way the NE555 works; it is an introduction to electronics! Very well done, Mr Winter, and many thanks.

    Half an hour of my life well spent! I bought a breadboard set with two 555s on a whim, and this made it very easy to understand what the chip is doing. Thank you!

    Excellent video. Half an hour of my life very well spent. I've spent far greater a time trying to comprehend the operation of the 555NE IC prior to this very well explained and comprehensible tutorial. Thank you for taking your time to compose such a well organized explanation upon a topic I've been seeking to comprehend.

    Finally someone Who explains 555 with detail, I am so happy when I found your video. Who says its booring? It's a splendid tutorial if you ask me, and beside you explain it for free, Only people who doesn't understand this would find it booring, but for me its really helpful and very easy to understand, and the circuit example you provide made me come up of something as my electronics project, Thank you so much and God blessed you!

    You helped me to really understand the 555 timer, thanks so much, because every other video never went in depth about what the functions and jobs of what each pin does. It's all "do this, and this happens" without the why. You explained the why. Absolutely terrific explanation of the chip. Thanks again.

    Wow great video. You have no idea how hard it is to find a clear concise video on the 555. Thanks I now have a firm grasp of both how to hook this chip up and a good general understanding of its theory of operation.

    A super video. What many of us need is a spot welding control circuit. Less than one second on & 2-3 seconds off. Have not found one yet that's simple & actually works. Thanks so much

    this was a brilliant video. i watched one where a guy simply wires up a 555 chip, but didn't explain everything so well. i followed what he did and only got an led that was permanently on.
    thanks for making this clearer. most definitely a good video.

  • @hydrolisk1792
    @hydrolisk1792 8 ปีที่แล้ว

    I have been having some troubles with 30 monostable "one-shot" circuits that I'm making for a really advanced security system. Using all the same value components I'm getting some of them that work properly and some that aren't working until a minute goes by. However by watching your lesson, I learnt that by installing a trimmer pot between Pin (6 and 7 tied together) and pin 8, I can fine tune them into the same timing! Many thanks for this upload mate!!

      @RobWinterTeacher  10 ปีที่แล้ว +8

      Thanks man. That's a nice thing to say! Most of my students call this boring... Hence what I said. I'm just amazed TH-cam has found this video so popular... Wasn't intended for anyone other than my students!

    • @micromed5
      @micromed5 10 ปีที่แล้ว +5

      Rob Winter everything is boring when we don't understand,but when things get clear and specially when you have passion for that thing it will be exciting instead. I'm looking forward for some other videos because I love electronics and i love the way you explain things and you helped me understand it better

  • @shadetreeprops805
    @shadetreeprops805 8 ปีที่แล้ว

    i can tell you how its popular, everyone else just shows how to hook it up. you show the how and why it is doing what its doing. and make it simple enough that anyone could understand what is going on. i thank you, if not for this i do not think i would have ever understood what was going on.

    • @RobWinterTeacher
      @RobWinterTeacher  8 ปีที่แล้ว +1

      thanks! I'm glad some people get what's going on at least! half my students still claim they don't get it from this video hence why I figured it was too complex/boring!

    • @shadetreeprops805
      @shadetreeprops805 8 ปีที่แล้ว

      Long yes, boring no. but i am a self taught person at this, and i am now getting into animating my props, so this stuff is needed. I would like to see a simple break down of PNP and NPN transistors the diffrences between regulars and mosfets, what they are used for why they are used, what are the diffrent things they can be used for. becasue they are the next thing i want to click in my head, and me understand..

  • @xXblueman23Xx
    @xXblueman23Xx 10 ปีที่แล้ว

    I thought you did a great job at explaining monostable and astable configurations. The use of circuit wizard was a great visual as well as the voltmeter and probe for graphing time. This can be pretty dry/boring stuff, but somehow you kept me interested for the entire 30 mins! Thank you for taking the time to make this video.

  • @RakVish
    @RakVish 9 ปีที่แล้ว +1

    Really liked your video. Was a nice, concise explanation with good use of simulations to explain its working. The examples illustrating where they can be used, and its connection to other circuits/chips (like the decoder) helped a lot. Thanks again!

  • @thomasfowler2964
    @thomasfowler2964 11 ปีที่แล้ว +1

    Thanks! Very simple and informative. I think I can work out how to make an Atari Punk synth work on 2x 555's instead of 1x 556 as all the successful schematics I can find online show! Also, a practical use for the photo sensor would be the armed-light for an alarm like you see on the outside of a commercial building. Invert it though: flashes in daylight so it's visible to someone looking for it; constantly on at night so it's less annoying to those nearby.

    • @RobWinterTeacher
      @RobWinterTeacher  11 ปีที่แล้ว +1

      Hi Thom,
      a 556 is basicaly just 2 555 timers on one chip anyway with common power and ground legs... shouldn't be that different to wire up. Glad you're learning and experimenting - That's how you learn.

    Very helpful! Thank you for uploading this. My solid states devices class's book "went out of print" so our teacher just gave us an encyclopedia of information to put on our flash drive which tends to get too in depth and hard to understand the way everything is worded. I got my final exam today so I'm trying to study like a maniac to get everything understood and engraved in my brain. This was a nightmare to understand from my flash drive but you sir have made it 100 times simpler. Thanks a ton, and I hope you have a fantastic day!

    Thank you for the excellent video , and for your time , much appreciated , I am a beginner to electronics only as a hobby , but I find it very interesting , only problem is there is so much information on TH-cam , and the Internet in general that it becomes even more confusing , so my question is , would you know any good BEGINNERS books or VIDEOS I could purchase , or could I source a course at maybe gcse level and hopefully go from there .
    I suppose you could class me as a mature student 54 years mature to be exact lol . But I find electronics fascinating and it's never too late to learn ........ I hope

  • @Hexsyn
    @Hexsyn 5 ปีที่แล้ว

    Suppose I only had the red LED in the monostable-feeding-an-astable circuit seen at 26:00 , in that case there would be nothing wrong with connecting pins 4&8 on the astable 555, then connecting the output from the monostable 555 to pin 8, right? If I'm thinking correctly, that would just mean that the monostable output is acting as the VCC for entire astable 555 timer, right?

    @andygozzo72 6 ปีที่แล้ว

    you can reduce the astable circuit by one resistor, you dont need 2 in the 'timing chain' feed, connect pins 2 and 6, connect resistor from output (3) to pin 2+6 , and capacitor from this junction to ground, with output taken from 3 as usual, this certainly works with the standard 555 or 556, but no idea about the cmos versions as have never used them
