It isn’t always clear what is meant by calling a device or a signal “analog” and “digital”.  This AddOhms tutorial explains the difference between analog and digital by using an analogy to clocks.  Old-school clocks with hands are a great example of “analog” while alarm clocks with digits as their display are an excellent example of “digital”.

Behind the Scenes

With this video, I decided to change the “format” a little bit.  Instead of hand drawing everything in the video, I started using photographs and motion graphics to explain things.  The cycle time is about the same, but I think the mix makes things more visually interesting.

Another change is that I’m no longer licensing the videos under CC.  Why?  Because I decided CC was a bad idea?  No, not at all.  This is the first video where I used stock material (hint:  the clocks).  I’m not sure I understand the license of the material and how it relates to a CC like license.  I need to meet with a lawyer to check my options there.

For the next video, I’m working on an all new introduction animation for the videos.  If you want to see the audio test I ran with some friends, check out this video.  The animation is the same in all 3 examples, only the audio changes.
