I modified it for my application. See attached.Simulation shows it won't toggle. It would be better to base your circuit on the tim17 bistable you linked to in post #22. That bistable will toggle ok with a ground-going pulse, provided the pulse source has a pull-up to >1V (e.g. to V+).
I've used a 1k resistor in another circuit. LED did not illuminate. I kept change resistor out til LED came on with 330.I have to agree it doesn't toggle. And for LED D2 instead of 330 ohms, maybe 1K.
What MrAI stated, definitely seems to be "lot more circuitry".I have no suggestion for making it toggle without a lot more circuitry.
That is VERY detailed. But, I do not even know where to begin on that drawing. Is there an "Over my Head" emoji for your response.Hi,
I believe what you need would be equivalent to a JK master/slave flip flop.
Check into that and see if you can use that.
I didn't included those resistors in my newer drawing.That one should work. You have wide latitude in resistor values and probably don't need the resistors across the B-E junctions.
Thank you for all your responses. You guys are great help. I did create a newer drawing based in the TIM17 drawing from post #22.
I need it to be GND trigger pulse Push ON/Push OFF. Have GND Out to illuminate 12v Bulb. Drive a LED when circuit is Active. Latch a 12v relay.
