I created a simulation of two LEDs using a breadboard and and using the 47K Ohm resistor approach it work, I could sense which LED was on or if neither were on.

However, sometimes it seems to get confused and misread, it is as if there is some interference or noise being picked up. I check all the connections and tried varying the resistors but it still happens.

Any thought?

I'm also going to pick up some lm78L05 to92 and give that approach a try as well.

Thanks again for the help and continued education
