Digital or Analog

Post by RocketRod »

Could someone please tell me what the difference is of digital or analog? Some I/O cards state that the are capable of digital and analog inputs. I am not totally sure, but are LEDS digital, and switches digital, and then what would analog be? Or point me to a good web discussion. I did a search here and did not find anything definitave. Thanks in advance.

As far as I get it, digital is a switch (input) or a LED (output), analog is a variable input..ie throttle, brakes etc or a variable output like a servo.
Probably you will get more sophisticated answers...

That's what I am finding out too. Hit most of the I/O board sites, and I guess they expect everyone to be born with an electrical degree. I did see that what you said is right in line with what I found. If it's varible, then its analog. So my best guess is; Toggles, momentary, micro switches and 45 degree are digital, pots & servos are analog. Hope I'm at least a little correct. I'm not sure how they would relate to voltage, watts or amps though. I'm a wrench, not a spark chaser. Thanks Jack!

Jack & Rodney got it right, but here is a slightly more technical explanation. I've posted a link to this site before, but you may want to look at this particular page on the site:
