In this schematic I made I'm trying to light up a a series of LED's but not in sequence "not yet" what I want is to raise the start of with the lowest voltage a LED can operate on which will be sorta dim but this is ok and expected "im counting on that" and as you raise the voltage the second LED will light up BUT (here is where my question coming in!) not light up the first one so on and so on, maybe I want to turn LED #6 and NOT LED's 1 through 5 ?!
And yes I know I'm using a voltage divider and thats because I dont want all LED's to light up with a the same wavelength or same intensity
Using this schematic I'm not sure how to incorporate the photo-resistor so I cant include it in there but the idea is that when a particular LED lights up above a threshold the photo-diode will help meet the condition in a algorithm
Before anyone starts to yell at me talking about that there are other "conventional ways" I KNOW and while practical they might be doing it the conventional way is only practical for that application not mines specially where the objective is to use less I/O pins on the given MCU. So if there is and I know theres gotta be a way to make this happen given the fact that we introduce the right components I know is possible, I can do this software wise but not hardware wise and this is why I'm here looking for help.
