Hey guys, i want to replicate the logic detection circuit used in the logic labs that i use in college. I want to be able to feed a digital level into the output and the level will be represented by either the red led turning on (for logic high) or the green led turning on (logic low.) its easy to do this by putting two leds in series with each other and feeding the output between these so that the output is either sinking or sourcing current to one or the other of the leds. Want i cant figure out how to make it such that the leds dont light when there is now output feeding them? Any ideas?
thanks,
Greg
