Oh my, don't be sorry, I do appreciate the help!

My background is electronics, 100% analog. I remember learning about binary & hex back in school ... nineteen seventy something *grin* and that's about the only place that I've ever used it. I do understand it, but relating it to electronics has me scratching my head. Old Dog New Trick Syndrome?

Now, if we need to take a single D cell battery and light up 3 white LEDs in series, I'm your man! I'd just as well like to leave that world behind though and learn digital. It's making my life easier, even though I've just begun.
