searching for a reliable circuit
LaserTazerPhaser:
What would be a reliable circuit without the need of programming a micro which would output a signal which is high when the input is high but goes low and stays low after the input goes low once and does not go high again even if the input goes high?
The input signal would be many minutes to hours.
These things can be done easily for short durations but long durations needs practical experience because since components can vary.
Dubbie:
Could use an active low latch and hook up to the q bar output. Just one small component.
soldar:
A simple flip-flop will do that. https://en.wikipedia.org/wiki/Flip-flop_(electronics)
LaserTazerPhaser:
as in a 4013 latch?
IanB:
A single AND gate will do that, or a relay if you want a mechanical solution. A circuit like this is used all the time for the "push to start, push to stop" switching arrangement on machinery. (If you push the red button momentarily the machine will stop, and it won't start again until you push the green button.)
