    And that just highlights the value of an oscilloscope -- you can think you know what's suppose to happen but seeing is believing. A DVM, even a good bench meter is never going to see this so an o'scope is pretty much...

    I looked at the Arduino site and didn't see anything about 256 equaling a digitalWrite versus an analogWrite but I guess I could have missed it. I can understand how variation is PWM frequency and PWM value could...

    Well I just discovered something else here... I've been using a PWM frequency of 75Hz and at 75Hz PWM=255 does not give full ON whereas PWM=256 does. However, if I use the default PWM frequency of about 488Hz it's...

    I've been laboring under the notion that a PWM value of 255 was the maximum value and with the minimum being 0 from 0 to 255 is 256 values in total. So, I was just checking things with my oscilloscope and...
