How can I make a circuit that works like a pushbutton without a pushbutton?
I am trying to make a circuit that would do the job of pushing a pushbutton just once but without a pushbutton in order to make it automatic.
A sensor activates it, and a latching relay circuit gets ...

How does this circuit behave? (cap charge/discharge)
When I pulse, start signal should be at least 50ms HIGH before falling. To do this I must design R and C values to estimate capacitor C1 charge/discharge times. I get the schmidt trigger part, but I'm ...
