Comparator to Bistable Latch First, undo the reset switch located at the top of the RS component. Then over at the comparator, notice the 100K resistor at the non inverting input- that's my photoresistor. I have the comparator set up to give an output signal which acts as SET, when enough light falls upon the LDR thereby reducing its resistance to approximately 17K ohm. So reduce the 100K down past 18K and you'll see what I mean. Here's my problem: I've got this circuit in a breadboard right now, but it isn't working. I separated the comparator from the RS and tested them both individually- they work great. But when I join them, no joy. As you can see the circuit operates splendidly here in simulation- so why doesn't the real one work? I am perplexed, and would very much appreciate your thoughts...
