From the circuit attached this post, we have the first Circuit working fine at the output of the comparator, but once you connect a Transistor to the output logic, the two led,( HIGH and LOW) will glow simultaneously, not withstanding the current state of the logic.
We have tried using both PNP and NPN to the output of the comparator, and the results on the Circuit 2,as we presented still have both led glow at the same time...
