    Vout = Vsource*R2/R1+R2 simple as that!

    at 16:30 minutes you said "2" to the power of ten. were did you get the two from?

    could i also use an op amp with negative gain?

    Good video, but did you mix your responses to the other comments up?

      Hi! Thanks! I don't know what you mean about mixing responses up. :-/

      Well youpattube1 said your video was "Pure crap" and you said "Hey, thanks for your comment! I'm glad you liked the video!" and Mark Flint said "Good tutorial - thanks!" and you replied "Thanks, this is one of my very old ones. :(" is all?

    • @AntonyCartwright
      @AntonyCartwright  7 лет назад

      Haha! I see! youpattube1 written a very negative comment without any reasons why, so I just made it positive for him. Mark Flint said thanks, and that's good, but this is one of my very old videos, and I've learnt so much more since then. The quality of the video isn't very good. :-)

    sir what is exactly that you mean 13.5Volt/3 = 4.5... and 4.5 that you divide by 1023?.please reply me.

      Hi, this video has been superseded by this one: ruclips.net/video/lec7kPv3VS8/видео.html :-)

    • @zawirzahid6506
      @zawirzahid6506 6 лет назад

      did you meant that this video is incorrect for the voltage divider method for arduino to read the value?.

    • @AntonyCartwright
      @AntonyCartwright  6 лет назад

      It's not incorrect, it's just old.

    • @zawirzahid6506
      @zawirzahid6506 6 лет назад

      Antony Cartwright sir i still dont understand that from where did you get 13.5volt and then you devide it by 3?.can you explained this.. In the video you did not mention about it.. the value of 13.5volt from where..

    • @AntonyCartwright
      @AntonyCartwright  6 лет назад

      Zawir Zahid I dont know... You'd have to watch the video. I can't remember what it was for.
