555 Timers, Button Presses and a little bit more

  1. Jul 10, 2006 #1
    I am trying to set up some 555 timers to either:
    1 - open a valve for a short period of time and then close it
    2 - activate some sort of switch that will push a button to open the valve

    it will be much more simple for me if I could find something that will push a button when triggered by a single 555 timer.

    also, with that situation the pulse would just have to be run once and a simple monostable circuit could be built.

    to have it push the button again all I would have to do is ground the reset leg, right? thanks PF
